Enrique Rubio, 03-10-2009 21:56
Enrique RubioDear friends:
I'd like to know your opinion about this Calycellina (?) species that grows on indeterminate hardwood (Corylus, Betula?) at 1200 m of altitude.
Apothecia up to 1 mm of diam., shortly stipitate, hymenium deep yellow, golden yellow at maturity, excipulum whitish.

Asci IKI bb. Apical apparatus apically enlarged. I hesitate about their croziers. I think they are negative, but sometimes it seems to have them.

Re:Calycellina (?) on hardwood
Asci are surely with croziers. The excipulum has thick-walled cells, which is not so obvious here because the cells are alive. In section the texture should be steeply oriented on the lower flanks. I don't hesitate to say Bisporella citrina, but I must admit that this species is misplaced in Bisporella and has actually affinities with Calycellina.

Dear Zotto:
I should have known so common species!!
I'm sorry

Re:Calycellina (?) on hardwood
No problem, common species are also interesting and often rarely documented :-) And who knows, perhaps someone has a different opinion?
