Observation 1633: Neolentinus lepideus (Fr.) Redhead & Ginns
When: 2006-12-17
Herbarium specimen reported

Notes: The oyster mushroom-like fruiting bodies were found growing out of the top of a pine stump in the Aptos hills between Aptos and Watsonville. The caps are yellowish and covered with a dense tomentose layer that clumps into dark brown tipped scale-like clusters. The gills and spores are white. The gill edges are broadly wavy but not serrate. The gills are quite wide and thick. The entire caps are dense, thick (up to 3�? at the lateral stipe attach point) with very thick, firm, white flesh. The taste and odor are mild. The caps are large – up to 9�? across. I am drying some chunks of this in case it turns out to be something interesting. It certainly appears to be an aberrant oyster mushroom except it does not fit the usual characteristics at all. Besides the growth habitat on pine and the tomentose/scaly cap, the fruiting bodies are much more robust and thick-fleshed than other oysters I’ve seen, even ones of the same size. Hopefully, someone will recognize this thing and be able to name it.

This sure looks like Neolentinus lepideus to me. It almost certainly belongs to either Neolentinus (brown rot) or Lentinus (white rot)

Combined ‘observations’

I (Nathan) took the liberty of combining the three separate observations Phil created into one. Multiple pictures of the same specimen should go into one observation. This is normally done by hitting ‘Add Image’ multiple times rather than ‘New Observation’ for each photo.

Phil called me yesterday about this collection. From the phone conversation, Phil said looks like a Pleurotus, but the cap has tomentose scales and the hairs are pigmented. I also asked if the gills were serrated, which they aren’t. He also mentioned that it was growing on pine. Over the phone the only suggestion I could come up with was Panus tigrinus from Fungi of Japan. Looking at the photo, I don’t think that’s a great match. However, the photo is familiar. I’m pretty sure I’ve seen specimens like this before. They were also older like this one appears to be. I think I just assumed the black spots were a secondary mold on an old oyster mushroom. However, looking at these shots, I think the fresher brown scales are a real feature of the specimen. I don’t have any good idea what these are.
