see: https://svampe.databasen.org/observations/10094757

Tiny ascocarps with tiny asci (23,5-26 µm long with fairly long stipes; sp.p. 18,5-19,3 µm). Partspores 3,4 x 2,8 µm. Spores 3 (or 4celled?).

cheers

Re : Micro-Preussia on goose dung (Branta?) - Denmark
Have a look at Westerdykella (syn. Pycnidiophora). This looks like what we called W. dispersa at IMI (if it had pycnidia as well as ascomata in culture) or W. multispora (if there were only ascomata).

Best wishes

Paul

Re : Micro-Preussia on goose dung (Branta?) - Denmark
yes, clearly a Westerdykella but I am not sure of the species. Keys to nigra but ....

thanks

Re : Micro-Preussia on goose dung (Branta?) - Denmark
Hello Paul!

I do not know these genres, having never met them; are there species with a different number of spores per ascus? Is there a determination key?


Thank you and have a nice day.


Michel.

Re : Micro-Preussia on goose dung (Branta?) - Denmark

They may well have spores that are initially 4-celled like Preussia and Sporormiella, but if so they fragment inside the ascus, and the asci always appear multispored. They are usually only found in cultural studies.

Best wishes

Paul
