Psilocybin Fungi Of Venezuela
(Setas, Champiñones)

A Desarrollar (Ingles = To Be Developed).

Venezuela will likely reveal several species in the genus Gymnopilus which produce Psilocybin. Gymnopilus species grow on wood (wood chip trails, fallen logs/branches, tree stumps, clear-cut debris, logging road wood debris, and at the bases of living trees). More photographs are needed to understand the current biodiversity emerging from this country. Please see:

Venezuela may have more Panaeolus species waiting to be found in fertilized garden soils, fertilized lawns (especially newly laid lawns with sod), and in fields with animal dung. This includes cow-grazing fields, horse stables and horse racing courses, equestrian trails, and possibly other large animal localities – like sites known for elk, buffalo, sheep, and/or elephants. Please see:

Panaeolus cinctulus

Panaeolus cyanescens

Panaeolus venezolanus
(Images Needed)
Pileus 20-35 mm in diam, subcampanulate to campanulate, smooth to irregularly rimose, dry, brownish gray to ashy gray. Lamellae sinuate, blackish-gray but mottled. Stipe 45-50 × 2-3 mm, cylindric but sub-bulbous, hollow, brownish gray to reddish, pruinose toward the base . Annulus membranaceous, thin, whitish to blackish from spores deposited. Context thin, grayish at pileus, brownish at stipe, with taste and odor slightly farinaceous. Spores (11-) 12-14.8 × 8.8-9.9 × 7.7-8.5 um, limoniform to subovate, with broad germ pore and thick wall, brownish to dark brown or blackish (KOH). Basidia 21.7-30 × 9-11.2 um, two- or four-spored, subcylindric or subpyriform, hyaline. Pleurocysti-dia none. Cheilocystidia 24.7-34.5 × 6-9 um, hyaline, subcylindric or vesiculose-elongated, abundant. Subhyme- nium and trama hyaline. Epicutis dry, formed by brownish (KOH) vesiculose-cylindric elements emerging from the surface. Hypodermium hyaline. Clamp connections present but scarce.
Habitat and distribution. Gregarious on cow dung or on rich soils: In meadows of the subtropical forests.
Known from Venezuela and possibly also present in subtropical and tropical regions of Mexico.
Studied material. VENEZUELA, N of Merida, San Javier del Yalle, July 27, 1971, Guzman 9177 (Type, MER; Isotype, ENCB).
- Mycotaxon 7(2): 221 (1978)

The genus Pluteus requires profoundly more amplified attention by mycologists in Venezuela. It is likely that several Psilocybin-producing species are currently growing on fallen branches, decaying logs, tree stumps, tree bases, logging roads, and on clear-cut debris in the forests. Excellent photography is now needed throughout this nation. Please also see:

Pluteus nigrolineatus

Venezuela may possess more species in the genus Psilocybe than what is listed below. This diverse genus exhibits species capable of growing from dung, wood, soil, and intermediate substrates. If you or someone you know locates a collection, please thoroughly photograph the species, dry it out completely, and save it (properly) for microscopy and DNA sequencing.

Host-Substratum/Locality: On soil in subtropical forest: Venezuela
Section: Zapotecorum
Description Page 103 Supplement To The Genus Psilocybe
Description: Pileus (10-)15-30 mm diam, conical to convex or subcampanulate, subpapillate or subumbonate, lubricous, even, slightly striate at the margin,yellowish brown or reddish brown, becoming paler towards the margin,readily turning blue-green to blackish when bruised or old.- Lamellaeadnate or sinuate, yellowish gray to brownish violet or dark brown sepia,edges whitish and subfloccoses; turning blue-green to blackish when bruised. Stipe 40-80 × 3-5 mm, equally cylindrical or slightly thickened at the base,somewhat flexuous, hollow, whitish to irregularly reddish brown or blackish,readily turning blue-green when injured, covered by whitish floccose littlescales, mainly toward the base. Veil well developed, cortinate and white,forming a complex subfibrillose or submembranous annulus, frequentlydouble. Context pallid yellow in the pileus and stipe, whitish toward thepileus surface, readily turning blue-green to blackish when cut. Dried basidiomata are completly blackish to black.- Odor something special butfungus-like, not farinaceous. Taste slightly fungal, subfarinaceous topungent. Spore print violaceous brown.
Spores (5.5-)6-7(-8) x 3-4 x3-3.5(-4) µm, subellipsoid or subovoid both in face and side view, brownish yellow, thin-walled, with a broad germ pore at one end and an acute shortappendage at the other.- Basidia (16-) 17.5-24 x (4-)5-6 µm, 4-spored, clavate ventricose, hyaline.- Pleurocystidia (16-)17.5-27(-28) x (4—)5-8(-9) µm, common, hyaline, subfusoid with acute apex or sublageniform witha short neck.- Cheilocystidia (14.5-)16-28(-31) x (4-)5-6.5 µm, abundant, hyaline, ventricose sublageniform, frequently with a middle middleconstriction with a short or long neck, sometimes bifurcate.-Subhymenium not well differentiated.- Gill tram a regular, formed byhyaline to pale yellow hyphae, thin-walled, 2.5-13 µm wide.- Epicutissubgelatinized, formed by 2.5-4 µm hyaline to pde yellow parallel hyphae.-Hypoder mium with hyaline or pale yellow hyphae or subglobose elements,5-17 µm wide, thin to thick-walled.- Clamp connections present.
Habitat: Gregarious on soil, in a subtropical forest (“bosque ombrofilomontano siempre verde”) with Cyathea and Blechnum, at 2400 m of elevation. Known only from the type locality.
- Supplement To The Genus Psilocybe

Psilocybe yungensis

Psilocybe zapotecorum (On boggy ground)
My Notes On Habitat/Substrate: Fairly common in cloud forests upon the highest 700 feet of mountain terrain. (A gully-like area where rainfall gathers and travels downward). Among living, woody small plant-life and decaying twigs/branches and leaves, but mostly clay-rich soil with sand. Well shaded area, and difficult to hike. Moist sand mixed with clay or clay-like deposits attached well to the stipe bases. Growing spread-out, but close-by as individuals, with a couple of specimens joined together strongly.

¡Hola! Pregunta importante: ¿Quién puede realizar de manera asequible (o libre) la secuenciación de ADN dentro de Venezuela para las colecciones Gymnopilus, Panaeolus, Panaeolopsis, Pholiotina, Psilocybe, Pluteus, Oudemansiella, Conocybe, Inosperma, Mycena, Galerina, e Inocybe?

Notas: Mushroom Observer necesita una fotografía más excelente de las especies mencionadas anteriormente. Por favor, siempre haga todo lo posible para fotografiar las tapas, branquias, tallos, sustratos y hábitats. Las fotografías en primer plano también deben incluirse siempre que sea posible. ¡Gracias!
