Incrupila sp. ?
Stefan Blaser, 05-09-2021 20:27
Hello everybody,

I hope somebody can help me with this one:

Substrate: decayed Wood (likely coniferous)

Macro: Apothecia 0.2-0.3 (-0.4) mm. With a slightly translucent, white disc and long, stiff, white hairs.

Micro: Hairs up to 100 µm long and 5-6 µm broad in basal part, tapering to a rounded to rather pointed apex, covered with coarse cristals. Asci 32-36x 5-6 µm, IKI+, with croziers. Paraphyses thread-like, about 1 µm in diameter. Spores 6.5-7.2 x 2.0-2.7 µm with two oil-drops.

It might come in the vicinity of Incrupila lignicola, but I find not much Information on this species. Maybe I am all wrong...

Many thanks for any help,

Stefan

Re : Incrupila sp. ?
I lignicola is a good choice! My first idea was a Lachnella parasitized by a Helicogonium. But Helicogonium with amyloid asci?

Did you compare Raitviir's description? That is not too bad. Maybe the statement of thin-walled hairs is wrong.

Did you verify the excipulum (thin-walled globulosa)? The substrate you could probably verify, in case the wood is not completely decayed. Type was on Alnus.

Re : Incrupila sp. ?
Danke Zotto,

Here are two pictures with excipular cells. Definitely thin-walled.

Spores are slightly too broad for I. lignicola.

Otherwise it seems to fit well.

I can double check the wood species when I return to the forest,

but I am pretty positive about coniferous wood.

However, there do not seem to be many collections of this species, thus substrate preferences are not sufficiently known.

Lieber Gruss,

Stefan

Re : Incrupila sp. ?
Yes, quite an unknown species. The more important is a trustable host identification.
