Re : A Poronia sp. from Panama
Hi Eduardo,
a long stalked species of Poronia is P. oedipus.
it is recorded from Panama: http://www.pnwfungi.org/pdf_files/manuscripts_volume_4/naf20093.pdf?

Re : A Poronia sp. from Panama
As I see now, you triggered a discussion about your find already here: http://mushroomobserver.org/98358?user_locale=es-ES?
However, here is the protologue of P. oedipus by Montagne (1840) attached.

Re : A Poronia sp. from Panama
The above-depicted fungus is a species of Poronia. Poronia can be put apart from Podosordaria by its anamorph which produce disarticulating conidiogenous cells now assignable to the form-genus Lindquistia.
And see:Mycol. Res. 104 (12). 2000. Pag. 1417.

Re : A Poronia sp. from Panama
Yes, is my original post in Mushroom Observer,There is a great discussion on this specimen, but there are different opinions. By the way, Montagne mentions "bulbous" base, but as we see in this specimen the base is a large ovoid sclerotia, and this feature is not mentioned in the P. oedipus reported by Piepenbring in Panama.

Re : A Poronia sp. from Panama
This could Xylaria pileiformis (Berk.) Curr. (Poronia pileiformis) be.
http://www.ascofrance.com/forum/11959/xylaria-guepini
Poronia oedipus (Mont.) Mont is smaller and has no bulb.
We have received a record from Panama Mrs Piepenbring.

Re : A Poronia sp. from Panama
Amigo: a juzgar por la parte fértil madura, se trata de una especie de Poronia. Cuál es el tamaño de las ascosporas? Como es la línea germinal? Las ascosporas están rodeadeas de una envoltura hialina diferente al perisporio (en caso de que éste sea visible al poner la ascospora en contacto con KOH al 5%)? Presentan las ascosporas uno o dos apéndices globulares en los extremos?
Saludos.

Re : A Poronia sp. from Panama
Hello Felipe,
of course I also know that for the determination of the type many factors are important. However, there are to my knowledge only such a great kind to manure, which I would describe as Poronia pileiformis . You got yourself but Xylaria (Acta Botanica Mexicana 42, 1998) called. Do you now have a another opinion?

Re : A Poronia sp. from Panama
Hi,
I attach the description by Montagne on Poronia oedipus (little more extended as in the protologue) as he gave it in de la Sagras volumes on the natural history of Cuba (for quotation I add the title too). I only have a poor copy of the figures to it. (who has a higher resolution copy of the "Atlas" ?). This one is from the New York Public Library site: http://tiny.cc/pxazlw?
My impression is that what he describes as the bulbous base of the stipe is merely the sclerotium. What do you think?
Regards
Martin

Re : A Poronia sp. from Panama
Las ascosporas miden 25 - 30 x 12 - 15 micras, ovales, oscuras, no se observa linea geminal, ni envoltura hialina ni apendices. Incluyo un detalle del esclerocio.

Re : A Poronia sp. from Panama
Dear Peter: My concepts of Poronia erici, P. oedipus and P. punctata are in Acta Botánica Mexicana (1998). 42:15-23. There, I left Xylaria pileiformis sensu Paden because (as I wrote elsewhere) I was, and still do, not acquainted with its anamorph, even though I had the strong feeling it is a Poronia (less plausible Podosordaria), judging its gross morphology, softness, habitat, and ascospore type.
Greetings!

Re : A Poronia sp. from Panama
Estimado Eduardo: El tamaño de las ascosporas cae en el rango de las de Poronia oedipus, aunque la presencia de esa estructura tipo esclerocio en tu colección es desconcertante pues no la he visto ni en mis ejemplares de P. oedipus ni en la literatura referida a dicha especie. En mi experiencia P. oedipus posee una base bulbosa y nunca (quizás por su ausencia o por error al colectarla) he presenciado tal rizomorfo esclerótico.
Saludos!!!
