Fungicolous discomycete on Merulius tremellosus
Alex Akulov, 23-10-2011 12:56
Alex AkulovDear Friends
Can you advise me about mysterious fungicolous discomycete sample, which I have collected recently? It is sligthly immature, but some important for identification structures already was formed.

Grateful before,
Alex

Re : Fungicolous discomycete on Merulius tremellosus
Hi Alex

the fungus looks mature! But the free spores you show look like Chalara conidia.

I remember to have seen such spores but not where. You don't have it fresh? The contents of the living paraphyses could help. Are there any hairs?

Thank you, Zotto
I see not any hairs. The sample was collected 2 weeks ago and is a little dry.
I'll try to make additional preparations of this fungus.

Re : Fungicolous discomycete on Merulius tremellosus
maybe you succeed with a section? Excipular structure is always important.

Re : Fungicolous discomycete on Merulius tremellosus
Dear Zotto
You are right. Ascospores really widely fusiform, with two large drops;
in the average 5.8 - 6.0 x 2.8-2.9 (within asci - much smaller: 4,9-5,2 x 2,8).

I find no any characteristic hairs. If they are present, morphologically indistinguishable from paraphyses.

Re : Fungicolous discomycete on Merulius tremellosus
I have one idea: Look on the DVD for Calycina (Svrcek used Calycellina) guttulifera Svrc., especially 5177a, or the type 7107. The species is not easy, and I have seen only 2 fresh collections which probably belong to 2 different species. But your fungus could well be guttulifera, though the apical ring is a bit different in your fungus (broader and stronger blue).

In the living parapghyses is a distinct refractive vacuole, and towards the base densely septate.
