Observation 147541: Tricholoma (Fr.) Staude
When: 2013-10-05

Notes: I lifted this from the table of the MAW Fall Mushroom Fair at Brookside Gardens, so I don’t know where it came from, the substrate, or possible host.

Cap (nearly flat when fresh) and stipe are entirely white; stipe is smooth, without a ring, and has a particularly pointed base. Smell is distinctly unpleasant, possibly with strong chlorine overtone. Both cap and stipe have become a bit more yellow or tan in the 24 hours since the Fair. Margin is a bit striate on one side only due to the pressure from the table while the mushroom laid on its’ side. Margin has thin band of sterile tissue which is not strongly rolled inward. Margin is not wavy.
KOH caused pale yellow stain this morning which quickly became tan.

Gills are distinctly notched at stipe and appear almost free in cross section.

2 records of T. sulphurescens in GenBank, both from Venice Museum Fungal Collection

This one is not really in the key, is it?
