Hyaloscyphaceae on Rubus canes
Enrique Rubio, 20-07-2010 14:30
Enrique RubioHi to all:
I need your help about this small (up to 0.25 mm), white, sessile, cupulate, densely gregarious and hairy ascomata that grows with no subiculum on Rubus fruticosus canes.

Hairs septate, apex acute or obtuse, not granulate, not basally inflated, very difficult to dissociate

Ectal excipulum prismatica.
I don't know the apropiate genus for this fungus. The hairs seems not to be typical for Hyaloscypha. Perhaps Psilachnum or Psilocistella are better for it?
Many thanks again

Re:Hyaloscyphaceae on Rubus canes
Hello,
if this is a Hyaloscypha then H. fuckelii var alniseda is one option. The spores are though too wide. Should be in these limits: 6.1-10 (-12)x2.0-2.9 (-3.2) (from Karstenia vol 29 no.2).

Thank you Marja, but the hairs are no typical for Hyaloscypha (see my card of Hyaloscypha fuckelii var. alniseda in Ascofrance).

Hola Enrique
The spores remind to those of Hyaloscypha albohyalina var. spiralis. Huhtinen talks about a 3% of populations with smooth hairs or inconspicuously warted hairs. Maybe this is one? But wait to other opinions...

Hello Raúl.
Perhaps you are right, but I think the hairs have not the typical appearance of the Hyaloscypha species.

Re:Hyaloscyphaceae on Rubus canes
Hi Enrique,
i think Raúl is right, for me the hairs are not so untypical in Hyaloscypha and all the rest fits well.
In Psilocistella there is no fitting species to my knowing.
