Bonjour, En regardant un Mollisia sur une Cupule
Ascodesmis nigricans?

Bonjour tous
Although I have yet to spot the ascomata I have found three groups of eight spores in a mount. The substrate is the small droppings of young sheep in neutral grassland.
The distinctive ornamented ascospores led me to Ascodesmis, and, after consulting Le Gal and Doveri, I think almost certainly Ascodesmis nigricans based on:
Ascospore size - 10.9-12 x 8.9-9.4µm
Broadly elliptical ascospores - Qe = 1.2-1.3
Ascospore ornamentation - not forming a reticulum but formed of irregular warts often capitate/flat topped
As I have not collected an Ascodesmis to date, and as there are few UK records I would welcome any comments.
Amitiés
Chris

Re : Ascodesmis nigricans?
Altough the size is in the low range, the shape and ornamentation lead to A. nigricans.

Re : Ascodesmis nigricans?
Merci Beaucoup Nicolas et Michel
Je viens de localiser la monographie de van Brummelen dans Persoonia 11: https://www.repository.naturalis.nl/document/569775 et ses images sont très utiles. Il est toujours bon de trouver quelque chose pour la première fois - surtout quand on ne s'y attend pas.
Cordialement
Chris
