Hypocreaceae ?
Pavol Palo, 06-02-2014 20:54
Hi everybody,

I found this one on bark of death twig Salix sp.The apothecia diam. max 2 mm. Paraphyses cylindrical diam. max. 3 µm. The asci are ??? spores 80-110 x 8-10 µm. Ascospores Ascokonidia diam. max 8 µm. When I put 10% KOH turns weakly orange. The scospores 13-19 x (3)4-5(5,5) µm


Thanks


Palo

Re : Hypocreaceae ?
Looks like a Claussenomyces. The ?8 round "spores" are balls of ascoconidia. Probably you can find submature asci in which the possibly septate ascospores are still visible that produce these ascoconidia.

Possibly Clasasenomyces atrovirens.

Re : Hypocreaceae ?
Is it an apothecium or a stroma containing perithecia? If it is an apothecium, then it is not Hypocreaceae. From the image it looks like an apothecium, but not clear.

Re : Hypocreaceae ?
Hello in the round,
these similar fungus we have determinate than Tympanis xylophila P. Karst. (Claussenomyces xylophilus comb.nov. Baral ?). The micros are not the best, but its to see, how the muriform septate ascospores (in the left pictures) decay and unite to the balls of ascoconidia. In our opinion its difficult, to see the both in good condition in the same time.
Greetings Peter.

Re : Hypocreaceae ?
Yes it could be xylophilus, Peter. But you must verify the shape of the ascoconidia, very narrow and allantoid in that species. Here is a find photo by Ingo Wagner.

The fungus of Pavol has apparently rather small asci, not really sure what it is. And the free 3-septate spores you showed us, do they come from the`se asci?

Re : Hypocreaceae ?
Hello  Zotto,
with "we" in my last post were I. W. and I believed. He was my "pupil" and just with this photo if it could have been that we would have done this finding together and would have determined.
The collage is also no accurate documentation, but should show Pavol towards only the unusual development in this type.
Greetings Peter.
