Re : Is this a primitive ascomycete?
Hi Oluna & Adolph..
Perhaps it is a basidiomycete. Cystofilobasidium species are similar but bear their basidiospores on a swollen cyst. Maybe your species has a reduced cyst. The spores look like basidiospores to me. The attached picture is an isolate from a hibernating bat in a cave. It looks something like yours, although it has a large cyst and round spores.
