Yellow anamorph on Urtica
Juuso Äikäs, 11-03-2022 17:29
This is a finding from early 2020, found growing together with the anamorph of Calloria neglecta.

I have only a few macrophotos and one microphoto of this left, showing some hairs and a blue reaction. I didn't find any asci.

Any ideas what this might be?

Re : Yellow anamorph on Urtica
Hi Juuso,

Where the nights still frosty? Maybe there were no asci and spores, because they have been frozen and broken.  Looks like  belonging  to Nectriaceae.

Re : Yellow anamorph on Urtica
It was February, so it's quite possible, even though it was an unusually warm one...

Re : Yellow anamorph on Urtica
Looks like the common Calloria neglecta in a conidial state, conidia string cells can be seen in your micropic.

Re : Yellow anamorph on Urtica
But this was actually growing mixed with the anamorph of C. neglecta (the orange ones in this pic).

Here's a micropic of the normal orange anamorph.

Re : Yellow anamorph on Urtica
Hi Sorry, didn't see the second conidia. Nectriaceae tend not to have hairs. Being small than Calloria, I can only suggest Cistella acuum, yellow with hairs and smaller. No evidence!
Bestw Cistella grevillei is better.
