Hebeloma oreophilum

Ciri dan struktur

Cap 1.0–3.8 cm in diameter, convex to umbonate, sometimes strongly, margin smooth, often involute when young, tacky when moist, usually not hygrophanous, but we have occasionally seen collections that are, unicolored or variably two-colored, at center dark olive buff to brownish olive to umber to cinnamon or sepia to brick to dark brick to fuscous, sometimes cracked, at margin cream to pinkish buff to clay-pink, sometimes margin very thin, usually pruinose to tomentose, usually with remains of universal veil, partial veil present. Lamellae whitish then pale clay brown, emarginate to broadly adnexed, maximum depth 3–8 mm, number of lamellae {L} 40–48, droplets absent or very small (lens), white fimbriate edge sometimes present. Stem 1.5–7.0 × 0.3–0.65 {median} × (0.3–1.0) {base} cm, at first whitish later brown downwards, apically with whitish fibrillose ring zone, sometimes with indistinct belts, downwards with suggestion of a fibrillose ring, pale sordid brown, pale watery brown, downwards dark brown when rubbed, cylindrical, rarely clavate, stem Q (4.2–)5.5–8.7(–15), pruinose at apex. Context firm, stem interior stuffed, later hollow, stem flesh discoloring from base usually. Smell raphanoid. Taste raphanoid, slightly bitter. Spore deposit brownish olive. Spores amygdaloid, occasionally ovoid or limoniform, usually weakly papillate, on ave. 11.0–14.0 × 6.5–7.5 µm, ave. Q = 1.6–2.1, yellow brown through brown, guttulation variable, almost smooth to weakly ornamented (O1 O2), perispore not or somewhat loosening (P0 P1), distinctly to rather strongly dextrinoid (D2 D3). Basidia (25–)26–33(–36) × 7–9(–11) µm, ave.

Habitat dan peran ekologis

Widely distributed and apparently common in Greenland, but never recorded from the East coast (only north east, see habitat). Described recently (Eberhardt et al. 2015a) from an alpine site (1970 m) in Slovakia and still only known from few countries. In Europe, it is recorded from northern Finland, from the Subarctic and Arctic zone and from the High Arctic zone on Svalbard. Outside Europe, it is known from low alpine and alpine sites in the Rocky Mountains and Canada (Beker et al. 2016, Cripps et al. 2019). Circumpolar, arctic-alpine to subarctic. Eighteen collections, six recorded with Salix glauca, four with S. arctica, three with S. arctophila, two with S. herbacea and one recorded under Alnus alnobetulae ssp. crispa. The absence from the calcareous, well-investigated Jameson Land on the east coast may signal a preference for more acid soil types. In the low alpine Rocky Mountains, Cripps et al. (2019) found it a number of times with Salix planifolia, S. arctica and S. glauca.
