Setose pyrenomycete
Gernot Friebes, 07-07-2015 13:30
Hi,

here is the second fungus. Again a short description:

On decorticated parts of a branch of presumably Fagus. The ascomata have long, dark setae that are slightly bent upwards. The asci are biseriate, negativ in IKI and very delicate. They measure about 80-100 x 12-15 µm. The ascospores are oval, filled with one big and a few smaller drops and measure about 14-16 x 6-7 µm. They are again rather delicate and tend to collapse quickly when observed in water. The paraphyses are filiform.

Thanks and best wishes,
Gernot

Re : Setose pyrenomycete
Hi Gernot,

quite interesting, Zaca (portugal) postet a rather similar species in April, I have studied it. But Ascus tips react blue in IKI. Are you sure not to have seen any reaction?

I have identified the collection as Lasiobertia sp, but there was no described species fitting. Without ascus porus reaction, I think your one belongs to Coronophorales.

regards,
björn

Re : Setose pyrenomycete
Hi Björn,

thanks for sharing your opinion. It is really quite a peculiar fungus! In the meantime Martina Réblová wrote to me that she believes that this species is Phaeotrichosphaeria britannica. For illustrations and a description see http://www.cybertruffle.org.uk/cyberliber/59351/0081/002/0320.htm. I will check the material to see if the ascospores are indeed finely echinulate.

Best wishes,
Gernot

Re : Setose pyrenomycete
I can confirm that mature ascospores are light brown and have a finely verrucous surface. Overmature and germinatíng ascospores develop a middle septum. Really happy to have a name for this nice fungus!

Best wishes,
Gernot
