≡ Nolanea cf. subsolstitialis Largent (1994: 208) View in CoL
Description:— Pileus 15 mm broad, convex-campanulate, umbonate becoming depressed, hygrophanous, translucent-striate at the margin, elsewhere dull, glabrous to slightly fibrillose, smooth, dark orange-brown with olivaceous tinges, paler at the margin. Lamellae emarginate, subdistant, ventricose, pale brown with pink tinges, edge slightly eroded, concolourous. Stipe 30 × 2 mm, central, cylindrical, slightly broadening towards the base, cartilaginous, glabrous, polished, smooth, dark orange brown, whitish at the base. Context thin, concolourous with pileus. Odour farinaceous. Taste farinaceous.
Basidiospores 6.4–7.6 (–8.0) × 4.8–6.4 μm, Lm = 7.1, Wm = 5.6, Q = 1.1–1.6, heterodiametrical, some subisodiametrical, 5–8 somewhat nodulose-angled in side-view, colourless. Basidia 18–31 × 8–12 μm, 2- and 4- spored, clavate to slightly ellipsoid, colourless or yellowish brown, clamped. Pleurocystidia absent. Cheilocystidia absent. Pileipellis a cutis, hyphae 4–8 μm wide, with abundant yellowish brown plasmatic pigment and abundant yellowish encrusted pigment. Subpellis differentiated, hyphae inflated, up to 76 × 32 μm, colourless or with scarce yellowish plasmatic pigment. Caulocystidia absent. Clamp-connections rare in the hymenophoral trama and absent elsewhere.
Habit and habitat:—Solitary, among moss, in Quercus - Pinus forest.
Material studied:— MEXICO. Jalisco, Municipality of Tequila, volcán de Tequila, km 12 road to microwave transmission tower, 9 September 2012, D. Montañez 193 (IBUG!).
Comments:—This tiny species with a mycenoid habit belongs to Entoloma subgen. Nolanea . It keys out in Largent (1994) as E. subsolstitiale , which is characterized by the small pileus with orange and olivaceous tinges, dark brown stipe, heterodiametrical basidiospores, and pileipellis with plasmatic and encrusted pigment. The Jalisco specimen is very similar to this species, except that Largent (1994) described it with a distinctly umbonate pileus and greyish lamellae, which were not noted in the Mexican collection. Similar species are E. bicoloripes (Largent & Thiers) Noordel. & Co-David in Co-David et al. (2009), which differs by the much larger basidiomata and exclusively intracellular pigment in the pileipellis; E. infula (Fr.) Noordeloos (1980) , which has a completely translucent-striate, dark brown pileus, slightly larger basidiospores, and exclusively encrusted pigment in the pileipellis ( Largent 1994); and E. solstitiale (Fr.) Noordeloos (1980) , which has a completely translucent-striate pileus and pileipellis with plasmatic pigment only ( Noordeloos 1992).
