bonsoir Hermine,
je t'envoie ça par email. Si c'est bien cette espèce je serai très intéressé de la voir de plus près. Merci de m'en garder un peu! De toutes façons, toutes les espèces de Xylaria fimicoles sont assez mal connues et méritent d'être réétudiées.
Amitiés,
jacques

Liebe Hermine,

das ist meine Strecke, aber von der Art habe ich noch nie etwas gehört. Ich arbeite an Xylariales auf Dung und bin natürlich sehr an eine Beleg interessiert (Artikel in 2-3 Jahren). Grundsätzlich dürfte aber keine Art der Gattung Xylaria auf Dung vorkommen. Wawelia, Poronia, Podosordaria und Hypocopra sind die Xylariales auf Dung.

Ich denke es dürfte Podosodaria tulasnei sein. Ist oberhalb der anhängenden Perithecien eine kleine Spitze vorhanden? Siehe Foto (N.Heine)


MfG Peter

Cher Jacques, merci beaucoup, ton support est fantastique. On verra, ce que mes connaissants en peuvent faire. Je leurs ai raconté de ton interet.

Bonne soirée

Hermine

Hallo Peter,

schau in pilzepilze wegen des Fotos. Und schau in Deinen Briefkasten.

Viele Grüße Hermine

hello,

The material I have studied of X. guepini incl. X. scotica (type material and other collections) were said to be radicating in soil previously manured. But I have not seen any stroma directly attached to dung (I have never seen living material). The spores lack a gel sheath, unlike most dung pyrenos. San Martin et al. (1998) decribed Xylaria equina on dung.

cheers

Thomas

Hi Thomas,

I know the article, but I think the man (San Martini) has made everything to Xylaria. So also Poronia pileiformis. A rich beautiful species with 25 cm height. Have we in Panama (See photo ,N. Heine) . Not all Xylariceae on dung have a gel sheath, for Wawelia has none. I also believe that X. equina is a Wawelia, or do you have a class with so attached perithecia? X. guepini is perhaps only accidentally grown through manure. What X. is coprophila by Wehmeyer I can not say because I lack the literature. X. cf inaequalis I know not, but who knows it on dung, only Rogers. In the original Berk. & Cur. is on dead wood.

Conclusion: The genus Xylaria on manure does not exist for me. But it could be possible that, in very rare cases, to find a lignicole and gramicole species in the dung.

Best regards Peter

I basically agree with you but am not convinced the San Martín taxon is a Wavelia. It is true that X. guepini could have been associated with dung by coincidence but it is strange that all well annotated collections mention manure of some kind. I will mail a scan of Wehmeyer´s description of X. coprophila. I have not studied the type.
cheers

Thomas

Dear Peter

I need your email address to forward the description

Hi Thomas,

Thanks for your opinion and your willingness to help. What speaks against Wawelia?

The e-mail address is always under the profile. Here again peterwelt@gmx.de
