Paxillus     Genus

Cortinarius husseyiKey to Gilled Mushrooms     Key
This is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.

TricholomaAgaricales     Order
Fruiting body containing fibers (usually in the stalk)

Inocybe pyriodoraBrown, Olive, Orange or Tan Spored     Suborder
Gills not free
Spore print tan, orange, deep ochre, yellowish olive, olive brown, rusty or cinnamon brown or deep brown
Ring usually either absent or not membranous

Pholiota albocrenulataLignicolous Brown Spored     Family
Growing on wood

Gymnopilus spectabilisMedium To Big Lignicolous Brown Spored     Subfamily
Cap usually more than 2" across, and sometimes up to 8; usually tan, yellow, or pumpkin-colored

Paxillus     Genus     Fries

Paxillus atrotomentosus


Microscropic Characters


Paxillus is actually a "missing link" taxon (except that it's not missing!) between boletes and gilled mushrooms. The gills cross one another and become sorta poroid near the stem; and the gill layer can usually be cleanly peeled from the cap, just like the tubes of a bolete

Narrow down your identification:

Stalk absent
Gills bright orange or orange yellow
On coniferous wood, especially hemlock and pine

Paxillus involutusPaxillus involutus
Cap up to 6" across; light brown; viscid, at least at the disk, when moist; often slightly velvety
Fruiting body staining reddish brown when cut or bruised
Usually with birch, oak or pine

Paxillus panuoides
Cap up to 5" across; dingy olive to dingy maroon; no reddish-brown patches
