Bonjour Bernard,

The Fruitbodies look a bit gelatineous, could it be Cyathicula calathicola which is growing on Cirsium inflorescenses.

Amitiés,

Stip

Hi Stip,

Many thanks for your message. Indeed, the fruitbodies looks gelatineous. I don't have any information on Crocicreas/Cyathicula calathicola and don't know if the microscopy matches. On the web, the macro photos don't seem to correspond to my mushroom.

Best regards,

Bernard

Hallo Bernard,

spores should be (5)6-7(9)×2-2,5(3) Asci 55-63×4-5 but Zotto has a folder with spores 7-12×3-3,7

Yours are in between
there is nothing about septation but your collection appears to be overmature, calathicola is a original a spring-species

Amitiés,

Stip

OK Stip, big thank you for your new informations !

I imagine that the altitude affects the phenology of this normally spring species and that it is therefore possible to encounter it here in early autumn, at an altitude of 2500 meters.

Best regards,

Bernard
