I was just playing the devils advocate. I always like to go back and see if any one had found spices I have found and did not recognize it. Too bad is in a vault over there.

that for this to have been Hydnochaete, or anything else in the Hymenochaetaceae for that matter, some pretty obvious setae would have had to have been present, which neither do these micrographs show nor did I indicate in the notes all those years ago…

it’s in an unaccessioned area of the SFSU herbarium. i won’t have a chance to check for a long time, and there’s no one who can really look on my behalf and have any decent chance of finding it. :(

Do you still have the specimen? Did you see any encrusted cystidia when you did micro? The spores look like close to Mycoacia nothofagi, The basidia with four sterigmata fit the description and this specimen looks similar to one Gerhard put up here in 2011.
