Gernot FriebesHi,found on a decorticated Picea abies branch stil
Hello,I found this species between mosses that where growing on concrete. Size 2mm. I first thought of Octospora musci-muralis but I only found spores with 1 large drop and several smaller ones. Spores measure 21/23x9/10µm. Q>2. Paraphyses with swollen apex up to 8µm. J-
Can anybody tell me which species this is...
PS I don't know much about mosses so I don't know the name of the host
Thx
Ralph

IMG-2403-0001.JPGO. leucoloma would be my guess.
See red arrows pointing on Bryum argenteum (apart from this O. leucoloma fools around with other Bryums too).
Cheers,
Marcel
Problem is that my Q>2 (21/23x9/10µm) and for O Leucoloma Q<2 ...

Best,
Marcel
it looks like O. gemmicola. This species has somewhat narrower spores than O. leucoloma (19-23 x 8.5-10.5 vs. 20-24 x 10-12 µm. Host probably is Bryum dichotomum (rhizoid gemmae should be absent).
with best wishes

Cheers,

Thanks for your reactions. i think indeed it is it must be O. gemmicola
