Bonjour à nouveau, Voici une trouvaille d'hier.
Pleospora? on mosses
Marja Pennanen,
25-11-2012 17:50
these black spots are about 0,2 mm wide and seems to have some hair-like structures.
The spores are about 26-34x9-10.
Asci had allready been broken and when I tried another, they were immature, about 70x15.
I suppose, this is a Pleospora, but failed to find any fitting species.
Any good ideas?
Marja

Re : Pleospora? on mosses
Try Epibryon, that genus is similar to Capronia, and your fungus reminds me of Capronia.

Re : Pleospora? on mosses
Thanks Zotto!
I would try. Just have absolutely no descriptions of Epibryon.
Dannish pyrenomycetes don't seem to know that genus and internet is very quiet about that, too...
Still happy, this seems to represent a genus which is new for me :)
Best wishes from Marja

Re : Pleospora? on mosses
I remember the genus is treated in Döbbeler 1978
Mitt. Bot. Staatssammlung München 14: 1-360
I have only a few copied pages and not digital. Perhaps someone has it?
I suggest to send your images to Peter Döbbeler. His Email I will send to your private address.

Re : Pleospora? on mosses
Hi Zotto, Alain,
I contacted P. Döbbeler and he answered:
"there are several bryophilous species with dark brown
muriform spores described in the genera Pleospora, Pleosphaeria,
Teichospora. But the species circumsciption is unclear."
Alain, thank you for the interesting link. There is lot of reading to do, if I come to the conclusion, that I have time to try to read that ;)

Re : Pleospora? on mosses
But Peter Döbbeler did not utter an opinion of the possible genus of your fungus? The phrase "described in the genera" does not necessarily mean that these taxa today still belong there.
What you can do is to test with IKI, and/or with KOH+IKI (remove KOH with water before adding IKI). Epibryon has a hemiamyloid reaction of the hymenial gelatine (nicely blue in KOH+IKI), unlike Pleospora etc.

Re : Pleospora? on mosses
I am currently calling collections of these kinds of fungi from liverworts Pleostigma (Teichospora) jungermannicola as per Marsh et al. (2010). It seems like species described as Pleospora haploziae Racov., P. lophoziae Racov., P. hepaticola Watson are all very similar. My collections lack hairs on the fruitbodies but have often grown beside Bryosphaeria spp. which have hairs. What the natural classification is, I don't know. Stenroos et al. (2010) included one Pleostigma jungermannicola in their analysis.

OMG,
thank you again.
This collection I do not remember. Must dig it out from my herbarium.
