Collection location: Lafayette, Louisiana, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

The first 5 photos were taken by the person who found these mushrooms, in Lafayette LA.

From the person who found them, “Growing on a live willow tree. The oysters I usually find in this area do not have stems like the ones pictured. May not even be a Pleurotus species. Spore printing in the process. I’ll post tomorrow morning. All mushrooms were growing on the same tree within 5-6 feet from one another. Smallest one is 2 inches across, biggest one was 6-7 inches across”.

First photo appears to show remnants of a partial veil clinging to the cap margin.

Spore print was white, and quite heavy. Guesses so far include Pleurotus, Neolentinus, Hypsizygus. Upon request, the collector mailed me spores scraped from a print. The spores don’t seem to match any species from the proposed genera. Spores non-amyloid, globose to subglobose and large, with diameters/lengths up to about 22 mu.

Just saw your proposal.

Nice little trans continetal group effort here. Mushroom collected/photographed in Louisiana, spores examined in Pennsylvania, genus proposed from California, and section proposed from Maine.

I thought those spores reminded me of something… what I have called Xerula/Hymenopellis, and may soon need to get used to calling Oudemansiella. I’m guessing the “Xerula” types will be placed into a different section than the mushrooms seen in this observation.

Thanks Jacob.

The spores look a lot like some seen in photos of Oude online. Also, I didn’t make the connection… spores look a lot like ones I’ve examined from Hymenopellis/Xerula species, which are reportedly headed to genus O.
