Spiny anamorph
Nicolas VAN VOOREN, 16-09-2019 19:56
Nicolas VAN VOORENHere is a asexual stage of a pyrenomycete, collected on decorticated branch (hardwood), in a subalpine forest. The perithecia are very spiny.
Conidia measure 22-27 x 1-1.2 µm, with small lipid bodies.
Any idea?

Re : Spiny anamorph
Hi Nicolas,

the pycnidia are collapsed. Did you try to rehydrate them?

Martin

Re : Spiny anamorph
Yes, I did. They become spherical and looks like "sea ??urchin".
The microphotograph was made on rehydrated material.

Re : Spiny anamorph
my idea was, they could open like Pseudolachnea, obviously not. Conidia have no setulae/appendages? Seemingly not by your micrograph, but you never know... ;-)
