Hebeloma aurantioumbrinum

Ciri dan struktur

Cap 0.8–3.6 cm in diameter, umbonate or campanulate, sometimes slightly tomentose or adpressed subtomentose, at high magnification, margin smooth, tacky when moist, not generally hygrophanous, but often with hygrophanous spots, uniformly colored or variably bicolored, at center yellow brown to cinnamon to umber, but with orange elements, at margin pinkish buff to clay buff, usually very thin, without traces of any veil. Lamellae initially whitish then becoming darker and brown with maturity, emarginate, maximum depth 2 mm, number of lamellae {L} 26–42, droplets present and visible, white fimbriate edge present. Stem 1.0–4.0 × 0.15–0.5 cm, whitish lengthily fibrillose on whitish-pale ground, then sordid buff or yellowish, cylindrical, occasionally clavate, stem Q (4.7–)5.5–7, pruinose, particularly at apex. Context firm, stem interior stuffed, flesh not discoloring from base. Smell raphanoid, sometimes weakly. Taste mild or slightly bitter. Spore deposit clay buff. Spores amygdaloid, not or weakly papillate, on ave. 10.0–12.0 × 6.0–7.0 µm, ave. Q = 1.6–1.9, pale brown to yellow-brown to brown, guttulate, almost smooth to weakly ornamented (O1 O2 (O3)), perispore not or somewhat loosening (P0 P1), indistinctly to weakly dextrinoid (D1 D2). Basidia 28–38(-43) × 7–9(–11) µm, ave. Q = 3.2–4.4, mostly four-spored. Cheilocystidia clavate-stipitate, occasionally spathulate-stipitate or clavate-lageniform, occasionally characteristically with a median wall thickening, geniculate or septate, on ave. 45–61 × 7–8.5 (apex) × 4–5 (middle) × 4.5–5.5 (base) µm, with yellow contents, ratios A/M = 1.61–1.95, A/B = 1.62–1.98, B/M = 0.97–1.18.

Habitat dan peran ekologis

Hebeloma aurantioumbrinum is one of the five most commonly recorded Hebeloma in Greenland with 10.5% of the records considered here. It is common and widely distributed in arctic areas in Europe (Beker et al. 2016). From alpine areas, it is known from North America (Cripps et al. 2019), but not from the well-investigated alpine mountains in Europe (Beker et al. 2016). Circumpolar, arctic-alpine. Forty collections with a number of hosts recorded, including: Salix herbacea (11), S. arctica (5), S. glauca (5), S. arctophila (3), Salix sp. (5), Bistorta vivipara (8, but never as the only possible associate). The localities are also scattered between wet and dry places, but favoring wet areas with S. herbacea, without having a preference for specific soil conditions. Beker et al. (2016) also found a preference for Salix, including S. polaris.
