Unknown blue-violet asco
Ralf Dahlheuser, 19-06-2016 22:32
Ralf DahlheuserI´ve found this nice asco on soil, together with Trichophaea gregaria.
Unusually they have two different spore-sizes. Those of 26,9-28,6 x 8,7-9,5 µm and, fewer, some of 31,8-33,3 - 9,5 x 10,3 µm.

For evidence , I am grateful

Re : Unknown blue-violet asco
I would say Peziza gerardii.
My measurements are 26 - 31 x 8,6 - 10,4 µm (28,5 x 9,7 µm).

Re : Unknown blue-violet asco
Regarding the spore size of P. gerardii there's an article by Nicolas:

Van Vooren N. 2010. Description de Peziza gerardii (Ascomycota, Pezizales) et présentation d'une récolte à petites spores. Mycologia Montenegrina, 12: 33-40.

Best wishes,
Gernot

Re : Unknown blue-violet asco

Hallo Ralf,


Tanja and me have presented this nice species in one of the last issues of "Boletus" and we have also observed a quite big spore range, measuring 24-28,5-31 x 8-9,3-10,5 µm, but may be we have included some immature spores too.


BÖHNING, T. & GMINDER, A. (2015): Einige seltene oder gefährdete operculate Ascomyceten in Thüringen. - Boletus 36(2): 101-116.


best regards,


Andreas

Hello all,

thanks a lot, of course Peziza gerardii. I was off the track. Sorry.

@Andreas: Danke für die Literatur !
