Could the specimens of interest…

been the recipients of Gymnopus spores?

I did actually have one but put it in the Gymnopus folder. I’ve uploaded it here too.

people are going to assume it’s just specimen contamination.

Gonna have to pass on that.

Much easier to just get G. semihirtipes specimens sequenced.

you need to go through all the MO observations of G. semihirtipes & kin to find photos with this in the background.

For the record, I doubt that that paper I mentioned will ever be published

Pulk. Here’s a copy of my message to Danny Newman on this observation.

“I recently got some sequencing results back from Stephen Russell and I thought you might be interested to find out that my “mystery paintbrush” (MO#280425) find is actually a Gymnopus species. It was growing next to Gymnopus semihirtipes so I’m thinking it’s pretty likely that that my mystery paintbrushes are the “saprobic cords” of Gymnopus semihirtipes. I will get the specimens that were adjacent to these sequenced at some point as well. There was a 100% BLAST match for an “unidentified basidiomycete” from New Jersey that will be included in an upcoming paper on the “Diversity and distributions of saprobic cord-forming basidiomycetes in two small patches of forest litter”. The next closest matches were unidentified Gymnopus species followed by Gymnopus dichrous."
