Species List: Gymnopilus Species Demonstrating Green To Blue Spectrum Hues – P1 of 2 – Recommended For Study - (1356)
When: 2019-01-05
Observations: 34

Notes:

A present day, state-of-the-art test for the presence or absence of Psilocybin, Psilocin, Cyanescin (Baeocystin)※, Nor-Cyanescin (Nor-Baeocystin), and Aeruginascin – at a minimum – is needed. Undiscovered pre-cursors and post-cursors to Psilocybin should also be selected for testing, as well as an undiscovered MAOI (Mono-Amine Oxidase Inhibitor).

The following Gymnopilus species may all generate Psilocybin, Psilocin, Cyanescin (Beaocystin), Nor-Cyanescin (Nor-Baeocystin), and other mind-altering chemicals. A new study is strongly recommended to chemically investigate these species using the very best methods and the most contemporary equipment possible. Additional testing for the following is also needed: Bis-Trimethyl-Silyl-Psilocybin, Bis-Trimethyl-Silyl-Psilocin, Tryptophan, Tryptamine, Seratonin, Gymnopilin, Gymnopilin K, Gymnoprenal, Hispidin (a pre-cursor to Luciferin), Oligoisoprenoids, and Bisnoryangonin. The species list provided below is an investigative list.

Additional Recommendations:

🍄 Full genome DNA phylogeny is published. Sequences are uploaded to Genbank.
🍄 Atleast three (3) distinguishing features are provided to assist in future identification of each listed species. Emphasis is placed not upon microscopic characters, but on macroscopic characters – for in situ identifications. If necessary, additional taxonomic characters may be expandable (s.l.) by including observations made using a hand lens or loupe (10x, 20x). This can also be achieved and reproduced photographically. See collections with squamulose pilei demonstrating cyan to black scales.
🍄 Synonyms are determined and genus sections are updated.
🍄 Complete, improved taxonomic descriptions are published using all names listed above.
🍄 Paper is provided in 5-7 languages (English, French, Italian, Spanish, Arabic, Chinese, Russian).
🍄 All chemicals analyzed to determine chirality using Atomic Force Microscopy.
🍄 Paper is provided as a courtesy to the public.
🍄 Gymnopilus is carefully compared to – and distinguished from – the genus Galerina to prevent accidental poisoning.
🍄 Chemical transcience and lifespan are discussed and observed in lab myceliums, freshly harvested wild collections, and in herbarium collections.
🍄 A worldwide themed distribution map is shown (and intregated into) a month-to-month cycle showing the electromagnetic light spectrum changing throughout the year. This is important.
🍄 Taxonomically useful color photos are aesthetically published for each species.
🍄 Mating studies are performed. Compatability or non-comptability is determined when synonyms require additional evidence. In addition, Pholiota myceliums are selected for mating studies with Gymnopilus species to observe the possibility for cryptic cross breeds. Proof to conclude sympatric speciation or a lack of sympatric speciation is provided.
🍄 A careful comparison is made showing similarities and differences in symptoms after consuming Psilocybin solely, Alpha-Amanitin solely, and Grayanotoxin I solely. Antidotes to conclude the effects of each chemical should be published. A careful analysis of the effects from Amatoxins occurring in the look-alike genus Galerina is included.
🍄 Myceliums are observed in an experiment in which electromagnetic light (320-400 nanometers) is aimed using slightly nuanced distances and time durations. In contrast, (blue light 440 – 490 nm) and green light (490 – 570 nm) (see nanometer graph elsewhere) tests should be conducted with great patience in separate groups. Dextrose is added to antibiotic agar petri dishes in a separate test group (Test Group 4) in which the myceliums fully colonize, followed by repetitive exposures to light in the 320-400 nm wavelength in Test Group 1, blue light in Test Group 2, then green light in Test Group 3. Additionally, some colonized dishes are selected for cold-shocking to assist in primordia formation (Test Group 5). See the following speech and fast forward to 7 minutes in: https://m.youtube.com/watch?v=M9joL8spvS8#fauxfullscreen
🍄 Techniques of growing Gymnopilus species in mycelial culture and methods for fruitbody production are published, including growth parameters. A present-day, economic-scientific terrarium design is included to further increase the number of genera that can be studied outside their wild type habitats.
🍄 Quantification of blue-to-green collections are made, with emphasis on where (on the basidiocarps) this color spectrum most frequently occurs and why.
🍄 Every mycelium achieving luxuriant mycelium status is cloned and placed into standard, sterilized malt agar ALONG WITH several common bacteria species (individually) that negatively impact humans via gastronomy-related conditions. These myceliums will be tested as winning adveraries with anti-bacterial properties just as Alexander Fleming performed with a Penicillium species. Fleming was able to defeat a Staphylococcus species. Additionally, see the following test: https://www.researchgate.net/...
🍄 Detection of light-emitting or light-reactive bacteria on the stipitipellis, hymenium, and pileipellis is performed using a system like: https://www.hygiena.com/...
🍄 A contemporary world-wide monograph for the genus Gymnopilus should now be considered for publication with emphasis on how to discern between species using macroscopic features – whenever possible. When providing at least three (3) macroscopic differences, it is recommended that they be listed strategically as follows: Primary, Secondary, Tertiary.
🍄 Formally try to define words associated with olive color(s) as defined by mycologists over history. (e.g. Olivaceous, Olive-Gray, Green Olive, Black Olive, Etc.).
🍄 Names are updated on Mycobank, Index Fungorum, Species Fungorum, and Mushroom Observer.
🍄 Species names are proposed for all unidentified observations in this genus on www.mushroomobserver.org
🍄 Organize some photography sessions of species into gif files and add them to the digital publication(s).
🍄 Discuss the type species of the genus, Gymnopilus liquiritae (Pers.) P. Karst. 1879, versus the newly proposed type species by Gymnopilus picreus (Pers.) P. Karst. (1879). See https://www.researchgate.net/...

Preface: The traditional bluing seen in species in the genus Psilocybe is not paralleled in the genus Gymnopilus. Instead a nuanced color spectrum is exhibited ranging from bluish gray-green, aeruginous, variegated green and yellow, tinged greenish, dull bluish green, green or green-spotted, olivaceous (“darkolive”), greenish, very slightly bluish, and greenish-yellow.
An intuitive chemical investigation is now needed in order to better describe the related colors observed in this genus and their preceding, corresponding chemical reactions. Note that not all individual specimens in a Psilocybin-positive collection will exhibit these colors, and yet those same specimens can test positive for Psilocybin. Not all Psilocybin-positive collections will display these colors either. The “blue bruising” reaction which occurs quite often when handling species in the genus Psilocybe does not commonly occur in the vast majority (=nearly all) of Gymnopilus species. Important, too, is the chemical investigation of any toxins capable of harming humans or which interact with Psilocybin in any manner.

Discussion
Both specimens collected in northern Thailand were initially identified as G. dilepis based on descriptions by Guzmán-Dávalos (2003) and Thomas et al. (2003). This species is easily distinguished from G. penetrans, which produces a gray-brown to dark brown pileus with a white to grayish-white tomentose-arachnoid velum covering the whole surface (Holec 2005). The smaller basidiospores (4.0-6.0 × 3.5-5.0 μm) of G. punctifolius and the longer basidiospores (8.0-10.5 × 5.5-7.2 μm) of G. junonius clearly distinguish these two species from G. dilepis (Singer 1951; Holec 2005).
Gymnopilus dilepis is closely related to G. purpuratus (Cooke & Massee) Singer and G. norfolkensis B.J. Rees & Lepp, from which it is distinguished by differences in spore size: basidiospores of G. purpuratus differs are longer (7.5-8.7 × 4.8-5.7 μm; Rees et al. 2004) while those of G. norfolkensis are narrower (6.4-7.2 × 4.0-5.2 μm; Rees and Lepp 2000). Gymnopilus dilepis also resembles G. lepidotus Hesler, but the two species differ in the form of the cheilocystidia; additionally G. lepidotus is known only from Mexico and the United States (Hesler 1969, Guzmán-Dávalos 2003, Guzmán-Dávalos et al. 2003).
Our molecular analysis also confirmed the two Thai specimens as representing G. dilepis. The combination of morphological and molecular characters confirms G. dilepis as a new record for Thailand.

Gymnopilus junonius (Fr.) P.D. Orton, Trans. Br. mycol. Soc. 43(2): 176 (1960)
(Description From The genus Gymnopilus in Norway): Cap 4-15 cm broad, convex, fibrillose to somewhat scaly with appressed squamules, bright orange yellow to orange. Gills adnexed to adnate, first orange yellow then red brown. Stie sturdy, tapering towards the base and usually rooted, fibrillose, orange to yellow brown, with an ample, firm ring. Flesh yellow to pale orange; with an intensely bitter taste.

Cystidia 22-30 × 5-7 (broadest part) 2-3.5 (narrowestpart) um, ventricose-rostrate with a clavate, rounded or globose apex. Hyphae of epicutis ≤ 10 um. (Basidia, cystidia, and hyphae measuredin G004).
Ecology and Distribution: Of 24 Norwegian collections examined, all were found on dead or dying deciduous wood. Four collections wre made on Betula, 2 on Fagus, 2 on Quercus, and 1 on Tilia. The hosts for the remaining material could not be determined. The species grows solitary or gregariously, either directly on trunks of living, weakened trees or on dead stumps or logs. Sometimes it is found on buried wood or timber used in constructions as, e.g., railway tracks. It prefers old trees or coarse wood in or near man made habitats as parks, gardens, or countryside forests. Due to increasing cutting of old, weakened trees and removal of old, dead wood from the cultural landscape, the species is probably declining. Its main season is in September, but relatively many finds are from August and October. Gymnopilus junonius has a lowland coastal distribution from Bergen in Hordaland to Ostfold, and north to Oslo. The species is previously recorded from Norway by Blytt (1905), Lund (1957), and eckblad (1975).

MATERIAL STUDIED. MEXICO: STATE OF JALISCO, Municipalily or Mazamilla, Monteverde, Guzman-Davalos 4132 (IBUG, XAL, ENCB, MICH). U.S.A: Nuevo Mexico, Santa Fe Co., around Santa Fe, Barrows 618 (MICH).
OBSERVATIONS. This species is recognized by the color or the basidiocarp, glabrous pileus and tufled caulocystidia. According to Hesler (1969) and Moser (1983), this species has a yellow or light orange context, however in the Mexican specimens the context was whitish to yellowish. Furthermore, Hesler mentioned that this species has pileocystidia, however they were not observed in the material from Jalisco and, likewise, were not found in the material from U.S.A that was determined by Hesler. Horak (1968) also described Ibis species as lacking pileocystidia. G. liquiritiae has been cited from U.S.A, Europe and Japan by !mal (1938), Kuhner and Romagnesi (1953), Hesler (1969), imazeki and Hongo (1969), Moser (1983) and Smith-Weber and Smith (1985). This is the first record of its presence in Mexico.

Habit, Habit, And Distribution: On decaying wood, logs, and trunks of trees, New York and Tennessee, August – September.
Observations: This species has been thought to be related to, or even the same as, G. spectabilis, G. armillatus, G. magnus, and G. ventricosus. But, all these entities can be distinguished (see key to species). In G. spectabilis the pileus trama is interwoven, and caulocystidia are present in tufts or palisades (see also comments on page 23). In G. armillatus the spores are non-dextrinoid. In G. magnus the veil is fugacious and the pileus trama is interwoven. In G. ventricosus the lamellae are pale-brown becoming dark-cinnamon, the stipe is pale-brown, and the pileus trama interwoven.

Gymnopilus purpuratus var. purpuratus
(Description From Type studies on Basidiomycetes VIII): Spores 8—9 x 4.8—5.5 um, with a rather conspicuous warty exosporial ornamentation, without plage, well pigmented; basidia 21.3 × 7.3 um, 4-spored; cheilocystidia ventricose below, with a cylindrical neck and capitate apex, 20—25 x 3.8—6.5 um, neck 1—2.8 um, in diameter, capitulum 4.5—5.8 um in diameter; hyphae with clamp connections.
The type, on fern stems in England (Kevv), as preserved at K, is a naucorioid species of Gymnopilus, with characteristic macro- scopial characters, bitter taste, and should be known as Gymnopilus purpuratus (Cooke & Mass.) Sing. It is close to but different from Gymnopilus luteofolius (Peck) Sing. (cf. Revue de Myc. 18: 19. 1953).
(Description From PMOTW): Cap: 1-5 cm broad. Cap convex at first with an incurved margin, expanding with age to broadly convex to plane. Reddish purplish brown to purplish red with tinges of yellow and green. Surface covered with scattered fibrillose/floccose patches. Gills: Attachment sinuate, waxy yellow, becoming a brownish cinnamon yellow with spore maturity. Stem: 20-40 mm long by 2-4 mm thick, stout, narrowing upwards, with fine parallel striations and covered with fine, fragile fibrils. Yellowish brown overall, with greenish and yellowish overtones.
Microscopic Features: Spores bright rusty orange in deposit, 6.5-8.5 by 4.5-5.2 um, ellipsoid, lacks cystidia.
Habit, Habitat, and Distribution: Grows on rotting wood. In Europe, reported from pig dung mixed with wood chips. ALso sighted in south Australia in May.
Comments: Weakly to moderately active. Gartz (1993) reported that dried, cultivated specimens yielded .23% psilocybin, .21% psilocin, and .05% baeocystin. Later, Gartz (1994) found roughly similar amounts – .25 % psilocybin, .33% psilocin, and .03% baeocystin – also from cultivated specimens. This distinctive mushroom can be cultivated on wood chips or logs using techniques outlined by Gartz (1992). The full range of this Gymnopilus purpuratus is not well documented. I would expect it to become more common throughout temperate regions of the world as strains acclimate. Cultivators play a key role in its expansion. Gymnopilus sapineus, a closely related species, my also be active but has not yet been analyzed.

Ecology: In the Czech Republic, G. spectabilis is mostly found as a saprophyte on dead wood of broadleaved trees, especially on stumps, fallen trunks and wood in soil (roots etc.). Less frequently it grows as a parasite on roots or on the base of living trees. Most finds are from Quercus spp. (Q. robur if the tree species was noted). Other known hosts from the CR: Malus domestica, Pyrus communis, Acer pseu- doplatanus, Populus alba, Salix caprea, Carpinus betulus, Tilia, Betula, Ulmus, Corylus. Finds from conifers (Pinus) are known from Southern Bohemia.

Gymnopilus subpurpuratus Guzm.-Dáv. & Guzmán, Mycotaxon 41(1): 50 (1991)
Pileus 18-53 mm broad, convex, plano convex to plane, finally uplifted, dry, squarrose to apprcsed-squamulose, especially on the disc, small scales or fibrilles reddish brown to purple, back-ground color to orange yellowish, tight reddish yeUow or purple-yellow, scales sometimes evanescent with age, margin entire, with ferruginous-brown arachnoid remains of the partial veil; pileus surface staining green when bruising. Lamellae adnate with or without a decurrent tooth to subdecurrent. close, broad to subventricose, yelow to ferruginous orange or ferruginous brown when mature, edge entire to subfarinaceous, yellowish. Stipe 10-30 × 2-6 (-9) mm, central to execntric, equa slightly broader at the base, folded like an ‘L’ or suberect, fibrillose, grayish white with purple or reddish stains, solid to hollow. Veil arachnoid, ferruginous brown, forming an inconspicuous apical fibrillose annulus. Context whitish to yellow-whitish. Odor farinaceous and sweet, taste bitter. KOH staining pileus with otivaceous-green spots with purple margins; on the lamellae yellowish brown; on the stipe purple brown to almost black and on the context greenish yellow.
Spores ferruginous brown in mass, 6-8 × 4-4.8 um, ellipsoid, verrucuJose, germ pore absent, yellowish-orange-brown, with refringent content, dextrinoid. Basidia 19.2-24 × 5.6-7.2 um, bi-ortetrasporic, clavate or subcylindric, somewith central constriction, with granulose, yellowish gray content. sterigmata 1.64 um long. Pleurocystidia absent Cheilocystidia 16.8-28 × 5.6-7.6 um, apex 3.2-6.4 um in diam., flask-shaped, subcapitatc or capitate, some with a long neck, with granulose, yellowish gray contents. Gill trama subparalleL Pileus trama interwoven, hyphae 4-24 um broad, septate, with thin waiL Cuticle with hyphae 4-14.4 um broad, postrate, yellowish, except for fibrills, wich are yellowish-orange-brown, some with distinct incrustations. Pileocystidia absent caulocystidia 24-68 X 3.6-12 um. apex 4.8-8 um broad, cylindric, ventricose-cylindric subcapitate or capitate, some flask shaped or clavate, hyaline or rarely yellowish gray or yellowish range, present only in the stipe apex, in tufts, very common. Clamp connections present Laticiferous hyphae present A yellowish pigment is disolvcd when mounted in KOH.
HABITAT. Gregarious to eespitose in a garden on pine-wood of unknown origin.
OBSERVATIONS: G. subpurpuratus is characterized by the small fibrillose scales on the disc, the greenish stains and the veil forming an anular zone. The green staining suggests a relationship with G. aeruginosus (Peck) Sing., however, this latter species is greenish with yellow and reddish spots, more scaly, has pleurocystidia and has a different type of caulocystidia (Hesler, 1969; lmazeki & Hongo, 1971 and Valenzuela et al., 1981). It is also close to G. peliolepis (Speg.) Sing., but it has reddish-purple scales, does not stain green and the cbeilocystidia are rusoid or ampultaceous, non-capitate. It also is related to G. lureofolius (Peck) Sing. but is distinguished by the reddish to vinacous context, discoloring to yellowish (Singer, 1951-A & 1951-B; Hesler, 1969). G. luteoviridis Thiers stains green, but has pleurocystidia and no caulocystidia (Thiers, 1959). Macroscopically, it resembles to G. purpurarus (Cooke et Mass.) Sing., but that species has larger spores (Singer, 1969; Lazo,1984). The material Guzrnan-Davalos also has spores 8-12 × 4~.4um, that are ellipsoid-elongate in addition to the typical spores.
