Brief Description: [See More | Edit]

Pileus 2–10 mm broad, convex, margin not striate, sometimes slightly crenulated, surface smooth, matt, hygrophanous, colour when moist near the margin brownish orange (5C3), nougat to grey brown (5D3–6D3), fawn brown (7F4), near the centre concoloured or nutria brown (5F3), when dry near the margin orange grey (5B2), birch grey (5C2), greyish brown (6E3-6E4), dry near the centre concoloured or golden (5C4). Stipe (6–) 9–30 (–37) × 0.75–1.5 mm, smooth or with fine blackish punctuations in zones oriented horizontally, near the lamellae camel brown (6D4), greyish brown (6E3), chocolate brown (6F4), towards base sometimes darker, sometimes black or almost so all over, sometimes with white tomentum on base, flexuous, slightly narrowed near base. Lamellae 1–1.5 mm wide, L=12-18, l=0–1, deeply decurrent, milk-coffee to greyish brown (6D3–6E3), towards edge paler golden (5C4). Flesh elastic, with very strong naphthalene odour but also with farinaceous or other unpleasant components, in pileus orange white (5A2), greyish brown (6C2–6D3).

Basidiospores (5–) 5.4–6.3 (–7.2) × (3.8–) 4.1–4.8 (–5.2) μm, av. 5.9 × 4.5 μm, Q (length/width) = (1.08–) 1.22–1.4 (–1.55), av. Q = 1.31, broadly ellipsoid to ellipsoid, hyaline, smooth, inamyloid, not dextrinoid, thin-walled, hilar appendage 0.45–0.8 μm long. Basidia 4- spored, (28–) 33–42.5 (–49) × (5–) 6–7.5 (–8) μm, av. 37.7 × 6.8 μm, hyaline, narrowly clavate, attenuated and flexuous toward base. Basidioles cylindrical to narrowly clavate, often flexuous, obtuse, (17–) 24.5–37.5 (–49) × (3–) 4–6.5 (–8) μm, av. 31 × 5.2 μm. Pleurocystidia absent. Marginal cells on the lamellae not well differentiated, similar to basidiola on lamellar sides. Lamellar trama of strongly undulate and intricate, subparallel, scarcely branched and irregularly inflated, 3–10 (–15) μm wide hyphae, composed of 10–90 μm long cells. Subhymenium pseudoparenchymatic, 20–25 μm deep, composed of branched, dense, 3–5 μm wide hyphae. Pileipellis near the pileus margin a hymeniderm, mainly composed of sphaero- pedunculate, occasionally also obpyriform cells arranged in one rank, terminal cells measuring (10–) 20–39.5 (–58) × (7–) 10–17.5 (–24) μm, av. 29.8 × 13.7 μm, Q = (1–) 1.47–3.01 (–4), av. Q = 2.24; subterminal cells rarely inflated, usually cylindrical, short and small cells (shorter than 10 μm) very rare, usually unbranched, measuring (5–) 13.5–35 (–53) × (3–) 3.5–13 (–30) μm, av. 21.2 × 8.1 μm. Terminal cells of hyphae in pileipellis near the pileus centre usually somewhat longer, mainly clavate-pedunculate or sphaero-pedunculate, rarely obpyriform, (15–) 23–42 (– 66) × (6–) 8–14.5 (–21) μm, av. 32.5 × 11.3 μm, Q = (1.18–) 2.06–3.99 (–5.67), av. Q = 3.03. Pileus trama of interwoven, 3–10 μm wide, subparallel, irregularly inflated hyphae, composed of 10–80 μm long cells. Caulocystidia repent and dispersed or fascicled and ascending, thin-walled, often inflated, obpyriform of sphaeropedunculate, others broadly clavate, usually not flexuous, with terminal cells measuring (13–) 21–44 (–78) × (4–) 7–11.5 (–17) μm, av. 32.6 × 9.1 μm, with darker parietal and sometimes also dark incrusted pigments. Stipe trama of 4–10 μm wide, parallel, often anastomosed hyphae, composed of 10–120 μm long cells. Clamp connections absent in all tissues.
