Cheilymenia ?
Nivalys Sylvain, 03-03-2018 07:52
Nivalys SylvainBonjour à tous !

Voici un asco observé l'été dernier dans les Pyérénées sur bouse de vache, pour lequel j'aurai bien besoin de votre aide...

Observés sur bouse en prairie, à Quérigut (09), le 30 juillet 2017. Altitude 1.500 m.

Spores : 14,5-17,2 x 6,9-7,6 µm.

Amicalement
Sylvain

Re : Cheilymenia ?
Hello Sylvain,

although I have no experience beyond C. vitellina with this genus, for determining Cheilymenia it would be necessary to know if there is any spore ornamentation and how it looks like (longitudinally striate, verrucose, ...), the length of the marginal hairs, probably also how the hair bases look like and if there are any stellate hairs present (stellate hairs = two or more hairs originating from the same basal cell). Spore ornamentation needs to be checked under oil immersion (it's very fine) and on spores that turn yellowish inside in cotton blue (those stained blue inside are immature).
