Hygrocybe squamulosa

[ Basidiomycota > Agaricales > Hygrophoraceae > Hygrocybe . . . ]

by Michael Kuo

As species of Hygrocybe go, Hygrocybe squamulosa is pretty robust, with a cap that regularly gets 6 cm wide. Otherwise, it looks a lot like any number of red and orange waxy caps, unless you're willing to spend some quality time getting into the fine points of waxy cap identification: Hygrocybe squamulosa has a dry cap and a dry stem, gills that are broadly attached to the stem but do not run down it, and a finely scaly cap surface. Similar waxy caps include Hygrocybe miniata, which is smaller, and Hygrocybe cantharellus, which is smaller and features gills that run down the stem.

Description:

Ecology: Precise ecological role uncertain (see Lodge and collaborators, 2013); appearing in woods under hardwoods or conifers, often in the vicinity of, or fruiting from, well rotted, moss coverered stumps; growing gregariously or in loose troops; summer and fall; reported from eastern North America and from Washington. The illustrated and described collections are from Michigan and Québec.

Cap: 25-65 mm across; convex, becoming broadly convex, nearly flat, or shallowly depressed; dry or slightly tacky; innately, finely fibrillose at first, becoming minutely scaly; reddish orange to orange when young and fresh, fading to pale orange.

Gills: Broadly attached to the stem; distant or nearly so; thick; pale yellow at first, becoming orange; short-gills frequent.

Stem: 30-60 mm long; 4-10 mm thick; equal; dry; bald; pale orange to yellow, with a white base.

Flesh: Yellowish.

Odor and Taste: Not distinctive.

Spore Print: White.

Microscopic Features: Spores 5-8 x 3-4.5 µ; smooth; ellipsoid or slightly oblong, but only occasionally constricted; hyaline in KOH; inamyloid. Basidia 4-sterigmate; 35-45 µ long. True hymenial cystidia absent, but filamentous pseudocystidia sometimes present on lamellar edge. Lamellar trama parallel. Pileipellis a trichoderm of hyaline, clamped elements 5-15 µ wide; terminal elements clavate, irregular, or subacute.
