Orbilia xanthoguttulata?
Juuso Äikäs, 03-04-2020 20:45
Yesterday I found some Orbilias growing on a fallen branch of Populus tremula. The part they were growing on was raised above the ground, maybe 30cm or so. The color of the apos ranged from yellow to blood red and they grew both on bark and directly on wood. 

The spores measure 11.6-12.9 x 1.3-1.7 microns and the paraphyses have many bright yellow guttules. Am I right or could this be something else?

Re : Orbilia xanthoguttulata?
Yes of course it is. Could you please tell me the collection data? Populus is one of the many substrates.

Thanks for the conformation! I'll mail you the data a bit later.
