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.

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
