Used references: Field Guide to North American Truffles; How to Know the Non-Gilled Mushrooms; Mushrooms Demystified. Similar to Pyrenogaster and Radiigera, but lignicolous. Also has some similarities to Lycoperdon. I think Geatraceae has more features than Agaricales.

Recognized by sight: lignicolous, carbonacious, young FBs encased in conidia, darkening at maturity (though perithecia not discernible from photographs provided), somewhat Phylacia-like in cross section.

Splendid sequence!

This is an incredible sequence of photos, Eduardo! I don’t think I’ve ever seen a complete Phylacia developmental sequence before, and the shape/dimensions of the asci are not published anywhere that I have seen: that they are not monoserrate is incredibly interesting! Thank you for these; I’m really sorry I missed them when they went up in 2012.

Comentario de la Dra. Meike Piepenbring sobre este especimen:

“sin duda encontro una especie de Phylacia. Se trata de especies “gasteroides” de Xylariales. Normalmente, en especies de Xylariales, los espacios dentro de los cuales se forman los ascos son peritecios, cavidades con forma de botella, con un poro (ostiolo) en la punta que se ve como un poro en la superficie del cuerpo fructifero. En el caso de especies gasteroides, no hay ostiolo, los peritecios son cerrados (no son peritecios en el sentido escricto) y las ascosporas se liberan cuando el cuerpo fructifero se rompe.

En la foto …463, los gusanitos gelatinosos translucidos son los paquetes de ascos que salen de los peritecios cortados.

Nunca he visto esta especie de Phylacia. Gracias por las fotos! "

We would be pleased to have a specimen of the fungus here in the herbarium! The fotos of the new collection are really beautiful.

those sacks of free-floating spores are the asci.

Recolecte nuevos especimenes de este hongo, en diversos estados de desarrollo, y en los que se observa la estructura columnar de la gleba, pude encontrar los ascos, que son de forma globosa irregular. Estos ascos son muy efimeros y fragiles, por lo que no se encuentran en los ascocarpos desarrollados.

Aunque hay muy poca informacion tecnica, pienso que si es una especie nueva para Panama, ya que las tres Phylacias reportadas tienen ascocarpos mamilados, y esta no lo tiene, ademas su ascocarpo es mucho mayor que las otras Phylacias. 2 a 3 veces mayor. Si quieres enviare unos especimenes al herbario de la UNACHI.

si es P. bomba, sería entonces un nuevo reporte para Panamá!

Truly a fascinating fungus!

Glad to be a part of the discussion. That’s a great blue color on the sectioned sporocarp.

Las esporas son bastante grandes miden de 10 – 20 × 8 – 10 micras, pero estas no son hialinas, ovaladas a globosas, lisas, no tipicas de Xylariaceae. No he podido observar ascos, y veo que en la literatura no se mencionan ni hay fotografias. Definitivamente no es P. poculiformis, ya que la peritecia no es mamillada, ademas las peritecias maduras no son negras sino marron claro.
Y este genero, a pesar de ser ascomiceto si desarrolla una gleba.

Nice …

just after i submitted my answer, i saw Eduardos message below. Eduardo have you spore measurements?

Phylacia sp.
By: Tina Hofmann
2012-08-18 20:06:33 MDT (-0600)

Dear Eduardo and mushroom observers, this fungus looks like a species of Phylacia (Xylariales, Ascomycota). The genus is caracterized by peritecia that lack ostioles, during maturity asci and ascoma walls disintegrate and the masses of ascospores accumulate in the upper part of the fruiting body. The spores are liberated when the outer walls of the fruitingbody are destroyed. Ascospores of Phylacia lack germ slits. For Panama 3 species are reported, P. sagrana, P. poculiformis and P. surinamense.

Bueno, al final parece que es una especie de Phylacia, aunque aun no he encontrado ascos, voy a examinar nuevos especimenes. Ver: http://mycology.sinica.edu.tw/...

I can think of several people
By: Daniel B. Wheeler (Tuberale)
2012-08-16 21:43:42 MDT (-0600)

who would be interested in seeing this obs. I’d suggest emailing trappem@gmail.com your photos first, Eduardo. He likes to look at the photos before asking for a dried herbarium collection, just to be sure he can’t identify this before hand. Additionally, his father, Dr. James Trappe, professor emeritus at Oregon State University, might have a better handle on what this might be than I. You might ask Matt at the above email address for Dr. Jim’s email address.

seem to show a portion of a capitate columella with radiating lnes in the white layer. Very curious. While I agree that Pyrenogaster is similar, it should have peridioles present. I see no peridioles here. I do see capillitia.

Tal vez alguien conozca a algun experto al que se le pueda enviar algunos especimenes…

re: new microphotos
By: Danny Newman (myxomop)
2012-08-16 19:05:29 MDT (-0600)

odd. those do look like capillitia, which is consistent with a gasteromycete (and not at all consistent with xylariacious fungi), but the macro (and reported durability) is thoroughly pyrenomycete-like.

but not posted. You might be referring to this observation:


which now belongs to the HNB.UMSA account.

Here is another from the same location:


If no asci or basidia or clamps were visible, placement in either Ascomycota or Basidiomycota is equally uncertain. To quote Sammy Jackson, the absence of evidence is not the evidence of absence.

no ascii visible. Sordariomycetes not possible without ascii, right? Interesting obs. though. I was looking through the Internet for similar obs. though, and found some posted by Larry Evans of Phylacia in Bolivia that look similar. No photos of interior structures, though. No microscopy either.

By: Eduardo A. Esquivel Rios (Eduardo27)
2012-08-16 16:43:48 MDT (-0600)

No he encontrado ascosporos en ninguna de las observaciones, las esporas se parecen originar en un tejido parecido a agallas aciculares. Ademas es poco probable que las enormes masas de esporos producidas se originen en ascos.

find spore bearing structures

i suspect that asci are responsible for the (seemingly mixed) spores in your micrograph.

Might be capitate columella
By: Daniel B. Wheeler (Tuberale)
2012-08-16 12:28:43 MDT (-0600)

just under the gleba. Can you see the hollow area on both sides between the outer peridium and the inner columella (white area)?

Not really similar to anything I’ve seen before.
By: Daniel B. Wheeler (Tuberale)

But it has many of the features of Lycoperdales: sterile base, outer covering (crustacea? like a crab-shell? or more like a clam shell?) glebal mass, etc. This may have a different strategy for liberating spores than merely an open slit or crack in the top. It might need to be predated on by slugs or other arthropods in order to liberate the spores. Or perhaps there is an odor produced that attracts a certain animal to eat it. Much like truffles exude pheromone-like chemicals to attract animals for mycophagy. Too early to tell at this point.

By: Eduardo A. Esquivel Rios (Eduardo27)
2012-08-15 19:52:44 MDT (-0600)

Hay Lycoperdales de consistencia crustacea.. ? es como una cascara de huevo. Ademas parece ser que estos no tienen ninguna abertura para liberar las esporas. Las fotos de los cortes transversales muestran las masas de esporas debido a que se rompio la parte superior al hacer el corte.

Need cross-section
By: Daniel B. Wheeler (Tuberale)
2012-08-15 19:19:37 MDT (-0600)

of younger material if possible, Eduardo. This looks sort of Lycoperdon-like. Need to be sure spores not produced in peridioles when young, like Pisolithus and Pyrenogaster. Seems somewhat similar to Geaster/Geastrum.

By: Eduardo A. Esquivel Rios (Eduardo27)
2012-08-15 18:59:20 MDT (-0600)

No creo que sea Daldina, no es un ascomicota, los esporos no son de Xylariaceae. Los esporos son producidos en la parte superior en masas de color marron, como en gasteromycete.

By: Eduardo A. Esquivel Rios (Eduardo27)

Algunos esporocarpos llegan a 2 cm. de diametro
