Jacques FournierMinute yellow things on dead stromata of Eutypella caricae. I gave this one a try because of the small globose ascospores.
Apos yellow, 80-120 µm diam, obconical with a very short whitish stipe.
Asci tightly packed under a refractive pelicle, cylindrical with croziers at base, 25-30 x 4.5 µm, 8-pored, IKI-. Paraphyses cylindric to slightly apically swollen.
Ascospores subglobose, 1.8-2.5 µm diam, with a slightly eccentric droplet.
Zotto, with your key I arrived to Hyalorbilia erythrostigma. Is it plausible?
Thanks,
Jacques

Dear Jacques

yeah, exactly! This will be a new substrate. Could you please tell me the collection data? The species is surely not rare but easily overlooked.

You didn't see T-shaped conidia? They are rarely there, but would help in clarifying whether those finds in which the species grows on Orbilia apothecia are identical.

Re:Hyalorbilia
Hi Zotto and Stip,
thanks for your comments. The key worked well!
I found the fungus when pruning the dead branches of a Ficus.
France, Ariège, Rimont, Las Muros, 470m, on old stromata of Eutypella caricae on a dead decorticated branch of Ficus carica, 25 Apr. 2010, JF 10019. Eutypa lata was also present next to Eutypella.
I searched for the T-shaped conidia but I did not fing them. Instead I found clusters of large, elongated distoseptate pale brown conidia that also inhabit the old stromata, very different from those of anamorphs in Hyalorbilia.
Have a nice evening,
jacques
