Observation 204793: Leucopaxillus tricolor (Peck) Kühner
When: 2015-05-21
No herbarium specimen

Notes: Several tightly fused clusters fruiting in mulch bed at the side of a restaurant parking lot. The most striking feature is that these mushrooms are embedded in a copious white mycelial mat (see last photo) which adheres to the base when it is removed from the ground. Cap is dry, feels like fine quality leather, has an inrolled margin and measures 11 cm. in diameter. Gills are decurrent, white aging to an off-white yellowish hue. White spore print. Stem is stocky, dry, striate with a bulbous base, and measures 7.5 cm in length. Width is 2 cm. Flesh is solid and white. All parts of the mushroom are firm yet remarkably spongey.

Mycelial mat emerges as small mushroom cluster is dug up. It looks blue-ish in this photo but is actually white.

for this observation. I forgot to mention that the mulch bed these mushrooms were in was anchored by a hardwood tree, White Ash would be my best guess. There are no conifers in the area. Both Kuo and Arora indicate that L. albissimus prefer to be in the vicinity of conifers. Also, the odor from these specimens was faintly pleasant, not foul such is the case with L. laterarius or mildewy as in the case of L. amarus (which also prefers conifers and oaks). For these reasons and for the reasons in my original notes for this observation, I believe an ID of L. tricolor is best by process of elimination.
