Small fruitbodys on old burned sandy soil with Ceratodon
Enrique Rubio, 16-03-2017 17:18
Enrique RubioHi to everybody
I'd like to know your opinion on these scattered, small (0.2-0.5 mm), subturbinate, very shortly stipitate, semitranslucent, not gelatinous, glabrous apothecia, growing on sandy, old burned soil, among the moss Ceratodon purpureus, together with apothecia of Octospora rustica..
The hymenium and the excipulum are covered by a thin gelatinous, colorless layer making an epithecium. Asci 8-spored, IKI negative, with open, big, croziers as in many Orbilia species. Paraphyses with a small, roudish vacuole that does not stain in Crb. SCBs seem to be also present. Excipulum of hyaline, pyriform to roundish cells elongated towards the margo. Perhaps the free ascospores make narrowly ellipsoid microconidia.
I don't know what genus could be good for this fungus. Maybe it belongs to the Epiglia-Mniaecia complex?
Thanks again for your help

Re : Small fruitbodys on old burned sandy soil with Ceratodon
Hi Enrique
could you please send me the pics in higher resolution? I have no idea except that it shows some orbiliaceous features. The ascus base is typical of Orbilia (withoiut croziers, H-/h-shaped), also the paraphyses with their SCBs, but spores and ascus apex not.

A further candidate for molecular study....
