Bryoscyphus?
Georges Greiff, 06-01-2021 14:22
Hi All,

I found a whitish species on sandy soil with Bryum capillare and Ceratodon purpureus. I believed it was Bryoscyphus dicrani in the field but the (unliberated) ascospores do not seem to fit that taxon and the paraphyses appear to lack the distinctive vacuolar bodies present in many fresh collections of Bryoscyphus spp. I wonder if it fits Bryoscyphus "rhombispora" nom prov. Baral. I do not have enough good material for a good quantitative analysis but the ascospore dimensions are approx. 17-20 x 8-10, which seems too large. Found in South England.

Any thoughts or resources would be greatly appreciated. I can't seem to find Zotto's image gallery, which I recall has excellent images of Bryoscyphus spp.

Thanks,

Georges

Re : Bryoscyphus?
Ah, I think it is Mniaecia nivea...

Re : Bryoscyphus?
Yes, this seems more likely (or a related form). The paraphyses are not multiguttulate as they should be in Bryoscyphus.
Best, Lothar
