Hymenoscyphus on Picea cone
Juuso Äikäs, 10-01-2021 12:59
These I photographed last September. They were growing on the core of a fallen Picea abies cone. 

The appearance and microscpy are similar to H. fructigenus, but maybe the substrate would be a bit weird? Or could this still be that?

The asci didn't seem to have croziers. I think the paraphyses on the pic might be dead. Spores: 20.1 - 22 × 4.3 - 4.7 micrometers.

Re : Hymenoscyphus on Picea cone
Yes, asci without croziers and paraphyses dead.

This is quite impossible to tell, because there is no study on the H. fructigenus complex with modern methods. There are many sequences in GenBank, which form a good clade but several subclades, and there is some relation to the substrate indeed.
