Hyaloscypha
Stefan Blaser, 29-11-2013 10:00
Hello everybody

I would like to have your opinion to this Hyaloscypha(?) species. Could it be H. fuckelii ssp. fuckelii?


Substrate: Deciduous wood, probably Fraxinus


Macroscopic description:


Apothecia mostly 0.6-0.8 mm in diameter. Color whiteish translucent to somewhat yellowish/ochre. Margin with conspicuous hairs.


Microscopic description:


Asci 35-45 x 6-7 µm, pleurorhynch, pore amyloid. Paraphyses filiform with 2-2.5 µm diameter and sometimes slightly broder at apex. Spores variable in size and shape, mostly ellipsoid with two small drops, 6-9 x 2-2.5. Hairs straight or slightly sinuous, I measured up to 90 µm in length, basal cells slightly brownish (see photos).

Thank you for any help
Stefan

Re : Hyaloscypha
Hi Stefan

that is Protounguicularia barbata (= Olla transiens). 

The partially present glassy tips of the hairs are typical, also the spores and their droplets. The asci should be simple-septae but with basal protuberances.

Re : Hyaloscypha
Hi Zotto

Thanks a lot for your identification! Is this glassy tip the only character to separate Olla/Protounguicularia from Hyaloscypha species?

Re : Hyaloscypha
Dificult question. The hairs are wider, and the excipulum may be brownish, although we have included also brown taxa in Hyaloscypha in the meantime (hepaticola).

Maybe it is genetically clearly different. I thought the species should belong in Olla, but that was also not the best idea, the differences are too great...

Re : Hyaloscypha
Thanks a lot for the Answer. If taxonomy was easy it would be boring :)
