Mollisia (?) on wood
Lepista Zacarias, 16-03-2017 23:55
Hi everyone,
Recently I posted here a topic with a Mollisia species:
http://www.ascofrance.fr/search_forum/47719
After some hints of the participants (my acknowledge to them), I could recognize that it refers to a species with septated spores, which is usually called "Mollisia atlantica", name that seems to be not yet published. This time the observation was from a very faraway place (~100 Km), but the general features are identical except that, being alert for the possibility of the existence of septated spores, I could not found any evidence of them. Some details:
-Growing on decaying wood of (probably) Castanea sativa;
- Ascospores:
(8.3) 8.9 - 10.8 (11.3) × (2.7) 3 - 3.29 (3.3) µm
Q = (2.5) 2.9 - 3.4 (3.7) ; N = 24
Me = 9.8 × 3.1 µm ; Qe = 3.1
- K- on hymenium;
- IKI+ blue on the apices of asci; this result was obtained with IKI at a high concentration, since the low concentrated one gave dubious results;
- bottom of the apothecia (excipulum) with textura globulosa;
- the paraphyses seem to be more discrete than the specimen of the other topic and I have
doubts about its vacuolar content (not sufficient detailed photos).
Any hint about it will be welcome.
Thanks in advance,
zaca

Re : Mollisia (?) on wood
Hmm, your photos seem to me detailed enough but only the spores are alive. The vacuolar contents would be well visibe in the fresh state. I am sure it is a Mollisia, but more I cannot say. The spores are rather wide. Important is to check the KOH reaction of the VBs, but don't expect that a name can be found.

Re : Mollisia (?) on wood
Thanks, Zotto,
for your message. These Mollisia a really difficult to analyze and classify.
Best regards,
