Brief Description: [See More | Edit]

Odorous, rather firm, gregarious or subcaespitose ; pileus fleshy, convex or slightly depressed in the centre, smooth, hygrophanous, fuliginous when moist, paler buff-brown when dry, the margin curved and sometimes wavy; lamellae subdistant, broad, thick, arcuate, decurrent, pallid when young, becoming darker with age; stem smooth, stuffed or hollow, subflexuous, often compressed and attenuated below, coloured like the pileus; spores subglobose, rough, .0002 in. in diameter.

Plant 1-2 in. high, pileus 5-10 lines broad; stem about 1 line thick.
Ground under Pteris aquilina. Lake Pleasant, August.

Odor quite strong, resembling that emitted by some species of Golden-eyed lace-wing flies (Chrysopha). The colour of the moist plant is almost exactly like that of Lactarius fuliginosus, Fries. Related to Hygrophorus Cantharellus, Schw.

Basidiospores (5.4–) 5.6–6.5 (–7) × (4–) 4.4–5.1 (–5.6) μm, av. 6.1 × 5.8 μm, Q (length/width) = (1.13–) 1.21–1.34 (–1.4), av. Q = 1.28, broadly ellipsoid to ellipsoid, hyaline, smooth, inamyloid, not dextrinoid, thin-walled, hilar appendage 0.6–0.9 (–1) μm long. Basidia 4-spored, (30–) 36.5–45 (–50) × 5–6.5 (–7.5) μm, av. 40.8 × 5.9 μm, hyaline, narrowly clavate, attenuated and flexuous toward base. Basidioles cylindrical to narrowly clavate, often flexuous and apically constricted, ca. 2.5–6 μm wide. Pleurocystidia absent. Marginal cells on the lamellar edge well differentiated, clavate to obpyriform, pedunculate or not, (10–) 15–28 (–35) × (5.5–) 6.5–12.5 (–15.5) μm, av. 21.5 × 9.3 μm. Lamellar trama composed of strongly undulate and intricate but parallel, scarcely branched and irregularly inflated, 2–8 (–10) μm wide hyphae, some hyphae with yellow pigments. Pileipellis near the pileus margin transitions from a hymeniderm to an epithelium, composed of globose, sphaero-pedunculate or obpyriform cells arranged in 1-2 (rarely 3) ranks, terminal cells measuring (12–) 16.5–35 (–45) × (7.5–) 11.5–21 (–30) μm, av. 26 × 16.3 μm, Q = 0.94–2.42 (–4.5), av. Q = 1.67.; subterminal cells often inflated, some narrow cylindrical, short and small cells (shorter than 10 μm) rare, usually not branched, often bearing incrusted pigments, measuring (23–) 30–50.5 (–70) × (4.5–) 6.5–11 (–13) μm, av. 40.1 × 8.6 μm. Pileipellis elements near the pileus centre very similar to those near the margin, terminal cells of hyphae measuring (9–) 15–31.5 (–42) × (6–) 8–21 (–31) μm, av. 23.3 × 14.7 μm, Q = (0.82–) 1.05–2.36 (–3.5), av. Q = 1.71. Caulocystidia fascicled, thin-walled, repent or ascending, clavate, obtuse, usually pedunculate and flexuous towards septum, with terminal cells measuring (9–) 12.5–31.5 (–50) × 4.5–14 (–23) μm, av. 22.2 × 9.2 μm. Clamp connections absent in all tissues.
