T. moseri in Oregon

1. I edited the Notes to correct the Collector and Determiner.
2. Sava Krstic informs me that when this was collected, Steve Trudell suggested the name T. moseri on the spot. For whatever reason, we chose not to write it down on the slip, probably because we intended to look at it in some detail.
3. A.E. Bessette, A.R. Bessette, W. Roody, S. Trudell Tricholomas of North America (Univ. of Texas Press 2013), says that this species “appears to be widespread in the western mountains”, and there are plenty of herbarium specimens and MO Observations from California and Washington. But there’s little from Oregon — probably just a coincidence. I found only one herbarium record from Oregon (in the OSU Herbarium, OSC #70192, from Josephine County), and only one other MO entry from Oregon, Observation 133861. Sava Krstic also has a preserved collection from the east side of Mount Hood.
