When: 2009-06-08

Collection location: Bluestone State Park, Summers Co., West Virginia, USA [Click for map]

Who: Eddee (eddeeee)

No specimen available

This is a strange one for me coming from California. not really typical phylloporus Rhodoxnthus. The only thing i can key it out too is phylloporus leucomyceinus The base hypha is white not yellow. spore print is light yellow found growing under Virginia pine.

Recognized by sight: If I found that in California I would definitely call it T. rutilans and given the woody debris in the images, I would be comfortable assuming there was a buried piece of wood. The spore color would tell us immediately.

Kuo lists “lignin rich soil” in coiferous forest as a possible habitat for Tricholomopsis rutilans. Phillips lists “yellowish” as a possible spore print color.

For a “gilled bolete” type, I would expect the pseudo gills to decent the stalk. But the gills of Phylloporus arenicola reportedly do not descend the stalk, and may actually pull away from the stalk. This “gilled bolete” is reported by Kuo from coniferous forests of northern California or Oregon. If you can get a look at the spores under a scope, then if it’s Phylloporus the spores should be large with length more than twice as long as width… similar to spores of Boletus species.

not on wood

it was not on wood not even close to wood it in the middle of a strand of very large Virgina pines. The top is soft like a bolete. At first i thought it to be suillas pictus and i found Suillas pictus with in 20 fet of it.

if it was near or on wood, but than can be hard to tell with these.
