Hi,
here I have a small, greyish discomycete that grows on resin on a living trunk of Larix decidua (soc. anamorph of Bisporella resinicola). No real idea where to place it... Ascospores have up to 9 septa and measure up to 41 x 2 µm. Asci are IKI bb and up to 65 µm long. Paraphyses are hyaline, without content, sometimes irregularly branched and/or conspicuously inflated. Excipulum consists of roundish, hyaline, slightly thick-walled cells. The description is based on rehydrated material, photos are not mine.
Best wishes,
Gernot
photos: apos dry - apos rehydrated - ascus - ascus in IKI - asci and paraphyses - paraphyses with inflated parts - ascospore - asci in IKI - ascospore in IKI.
It would be easier to have the living features, for instance, did the paraphyses contain VBs, especially in their inflated part?
The only idea I have is Pseudohelotium, but that is only a guess.

collapsing is usually not a problem, in KOH the cells generally swell and look nice, especially in CR when hyaline. But I sections are not easy with dead material, especially when the apothecia sit on such crumbled substrate like old resin.
