Ascomycete on crust
Dieter Slos, 26-12-2012 10:24
Hi all,

I found this small ascomycete on a corticoid fungus. I have totally no idea where to start. Any ideas would be welcome. The spores are about 23 x 13 µm. I only found one fruitbody.

Regards,
Dieter

Re : Ascomycete on crust
Thanks Zotto,

Any idea of usable keys in this order? And I suspect this is the theleomorph because it produces asci?

Re : Ascomycete on crust
I hope someone else in this forum can help here. The hairs are surely important for an identification.

Re : Ascomycete on crust
I agree with Zotto about Erysiphales; always a challenge when you don't know the original host; to start with you need good details of the hairs (length, number and whether they have terminal ornamentation), plus how many asci are in the chasmothecium and how many spores per ascus . . .

Re : Ascomycete on crust
Oké, thx for the confirmation. It seems that I have to find more material before I can continue this quest.

Re : Ascomycete on crust
Hello Dieter
try and discover which host plant this came from - that is by far the easiest way to begin to identify members of the Erysiphales
best wishes
