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).
