Observation 12824: Phaeocollybia R. Heim

When: 2008-10-17

Collection location: Larch Mountain, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

This is only the third collection of Phaeocollybia I’ve found. I’ve been unable to find a matching name for it. It was located mere feet away from Phaeocollybia ammiratii (see other entry for this date). Cape: dark chocolate brown to nearly black, with ruby tints toward the rim, rim edged in white, 2.5 inches wide, conical, becoming somewhat umbonate in age. Grills: brown, somewhat mottled. Stipe: the portion I collected was at least 4 inches long, but I didn’t obtain the whole stipe; grayish-white near cap, becoming reddish streaked where bruised, and carker reddish-brown near the basal portion. Interior flesh of the base white, fibrous, somewhat tough, and bottom 1/3 of stipe with lots of humus still adherring to the stipe. Might be growing in or very near well rotted wood, as it was difficult for me to dig the base out using a knife. Center of stipe filled with cottony material. I collected only one specimen as the species seemed abundant for the area, but didn’t want to disturb it more than necessary. I did a search for Phaeocollybia photos on Google, and didn’t find anything remotely close to this color for a Phaeocollybia. Too dark, too brown, too small. I really thought this was going to be an Amanita vaginata until I could see the stipe.
