Black setose on Polypore
Marja Pennanen, 13-01-2021 22:05
Hello forum,

I found some tiny black and setose ones on Trichaptum abietinum on Picea abies bark accidently in an old collection of Trichia botrytis (myxomycete) from year 2011.

These are so tiny (0,1-0,2 mm), that I do not even try a macrophoto.

The setas are brown, septate, up to 120x4-5.

The spores are also septate having normally 3 septas (few only 2) and the sells at the middle are brown with hyaline end cells, 12-16x4-5.

Thought, that it would be easier to ask for help here than to try to determine something completely unfamiliar myself. Ideas?

Re : Black setose on Polypore
check this one Ascocodinaea polyporicola Samuels, Cand. & Magni, Mycologia 89(1): 159 (1997)

a possibility

cheers

Re : Black setose on Polypore
Dear Thomas,

thank you very much!

I tried to find something about this new-for-me-genus from net and found a view of a page with the description of A. stereicola, which seems to fit well. I did not find the description of A. polyporicola at all... So A. stereicola until proven something else ;)

What a luck to ask here, I suppose, that Munk would not have given me an answer evenif I would have been reading it for days...

Marja

PS: Does someone hapen to have Mycologia 89(1), 1997 sides 156-162 as a PDF?

Re : Black setose on Polypore
I vaguely remember that Unto S. had something like this (polyporicola?) on Trichaptum - in Finland! :-)

Re : Black setose on Polypore
Ooh yes, I checked the finnish list of species and suprisingly  found Ascocodinaea polyporicola there and thought that Unto must have found it (described 1989). I know very few persons (Unto) here, who are interested in pyrenomycetes.

Yes, they don't know what they are missing :-)
