Observation 222447: Tricholoma saponaceum group
When: 2015-11-07

Notes: Fruiting singularly from a small buried coniferous log. Old growth Douglas fir, Western hemlock, Western red cedar dominant in canopy.

Cap: Somewhat conate, dry and slightly powdery at apex. Distinct, thick white band around cap margin, central papilla is brownish/reddish tan. 1.5-3.0in. wide. Over all caste is olive green.

Stipe: Long white, waxy, somewhat slimy; tapering distinctly at base. 4.5in. long. Light olive green hue, lighter than cap. Light pink cast toward tapered base.

Gills: Same color as stem, or close to, somewhat free near margin. Yellowish olive. Spore print light yellow, almost white macroscopically.

Long stem is very similar to Phaeocollybia or Rhodocollybia collections, only all white. Slight pink staining where handled and at base.

Narrow cap is disproportionate to length of stem. Very long, deep rooting, tapering white, waxy.

Odor: non distinct, somewhat of cucumber.

I have been looking at this species on the West coast of Washington state for 3 seasons now. Grows singularly in moss at sea level in addition to this montane observation. Always associated with Douglas fir. I am proposing that this be named Phaeocollybia albamargino-olivacea.
