spores attached to hyphae

would tell you which spores are worth looking at. I don’t know if basidia morphology will be important. If there are clamp connections and there are spores, there would be basidia. Unless… this is an anamorphic stage, in which the spores are conidia. Either way, you’d want to see how the spores are attached.

Check for:
“Should have large, conical, encrusted cystidia and fairly large spores.”
which would point to Porostereum crassum

Clamp connections are large and abundant

I am seeing a few types of spores. Some of them may have landed on the specimen while in the dehydrator, however two types are pretty common in several slides and are likely to be coming from this fungi. I will update the notes and add micrographs.

at least to see if there are clamp connections, if not more characters.
