Re:Small blackish-brown Asco on rooten wood

Hi,
I think this is most likely a Capronia sp, ascospores dimensions would help but it is a poorly known genus.
Best wishes,
Jacques

Perz Piotr, 27-04-2007 20:34

Re:Small blackish-brown Asco on rooten wood

Spores 12-17um x 5,0-6,5um

Yes, spores-shape looks Capronia-like, you are right.

Re:Small blackish-brown Asco on rooten wood

Peut-être Capronia nigerrima ? Les périthèces ne seraient-ils pas sur vieux pyrénomycète et forment-ils un stroma ou sont-ils isolés ?

Re:Small blackish-brown Asco on rooten wood

Hi Guy,

Perithecies are isolated, on wood.

Re:Small blackish-brown Asco on rooten wood

Yesterday I was microscoping a small pseudothecium close to Mollisia sp., and I think it is C.pilosella.
In Ellis & Ellis is description: "short setae forming a compact ring around the ostiole and a few other scattered ober the surface" (p.29, fig. 107) and this is exactly my fungus:

Re:Small blackish-brown Asco on rooten wood

a.8spored, sp. brown spores brown, 3-celled, 16-18,5 x 4,9-5,8 (a little too thick).

Perz Piotr, 21-05-2009 21:50

Re:Small blackish-brown Asco on rooten wood

spores in IKI

Perz Piotr, 21-05-2009 21:51

Re:Small blackish-brown Asco on rooten wood

but if C.pilosella has only short spores around the ostiole, so is my first fungus the same species ?

best wishes
Piotr

Perz Piotr, 21-05-2009 21:53

Re:Small blackish-brown Asco on rooten wood

please note, that the spores in my first fungus are MURIFORME (C.pilosella has 3-celled sp.)
