Observation 156940: Phaeocollybia lilacifolia A.H. Sm.

When: 2013-11-11

Collection location: Jedediah Smith State Park, Del Norte Co., California, USA [Click for map]

Who: Noah Siegel (Noah)

No specimen available

Growing in mixed Sitka Spruce, Western Hemlock, Grand Fir and Redwood forest.

I haven’t scoped this collection yet, it could also be Phaeocollybia lilacifolia. The small size and slight rosy-lilac gills make P. rifflipes more likely.

it could be something not (yet) detailed in Norvell’s fine book.

I see lilac gills, not pink gills in young specimens. The cap color is off for rifflipes (too dark brown, no olive edge to cap in older specimens), and what you show isn’t very viscid (altho there were still dry conditions up that way, yah?).

the pith, if rifflipes, should be fibrous and pulling away to become hollow in age.

size overlaps between rifflipes and lilacifolia: 20-60 mm cap vs 30-100 mm cap.

lilacifolia DOES have a dark brown cap in age as well as lilac gills in youth; rifflipes has gills that are “rosy white to violet gray.”

scope it, Dano. photos aren’t enough here.
