Ciri dan struktur
Cap 0.7–2.5 cm in diameter, convex to umbonate, margin smooth, tacky when moist, not hygrophanous, uniformly colored or more often bicolored, at center sepia to fuscous or dark brick, sometimes with a thin tomentum, at margin dark olive buff to cinnamon or umber; sometimes with remains of universal veil, partial veil present. Lamellae yellowish ochre then brown, emarginate, maximum depth 4 mm, number of lamellae {L} 24–32, droplets absent, white fimbriate edge usually present, but weak. Stem 0.8–7.0 × 0.15–0.5 {median} cm, whitish or pale grayish then browner to gray brown, not darker towards the base, cylindrical, stem Q 4–13, fibrillose, pruinose at apex. Context firm, stem interior stuffed, later hollow, flesh usually discoloring from base. Smell usually raphanoid but sometimes without smell; taste not recorded. Spore deposit color not recorded. Spores amygdaloid, limoniform, occasionally ovoid, papillate, on ave. 12.5–13.5 × 7.0–7.5 µm, ave. Q = 1.6–1.9, brown, guttulate, almost smooth to weakly ornamented (O1 O2), perispore not or hardly loosening (P0 (P1)), weakly to rather strongly dextrinoid (D2 D3). Basidia 27–33(-36) × 8–9 µm, ave. Q = 3.0–4.1, mostly four-spored. Cheilocystidia usually lageniform or ventricose, occasionally cylindrical, occasionally characteristically with an apical, basal or median thickening, on ave. 41–51 × 4–7 (apex) × 4.5–6 (middle) × 8–13 (base) µm, ratios A/M = 0.9–1.13, A/B = 0.48–0.67, B/M = 1.75–1.97. Epicutis an ixocutis of 30 µm thickness (measured from exsiccata), maximum hyphae width 5–6 µm, sometimes encrusted, shape of trama elements beneath subcutis sausage-shaped and up to 19 µm wide.
Habitat dan peran ekologis
Recently described and still only recorded from a few alpine and arctic areas in Europe and arctic Canada (Beker et al. 2016). The Greenland collections are from the Low Arctic zone and High Arctic zone, but the species is rare and scattered. Circumpolar, arctic-alpine. Eight collections, six with Salix glauca, S. arctica and S. herbacea, two with undetermined Salix sp. The presence of Bistorta and Betula are mentioned, each on one occasion. Soil conditions are variable, but mostly calcareous. Salix was the only host mentioned by Beker et al. (2016). Some recent records from subalpine woodlands in central Europe suggest it may also associate with conifers (Grilli et al. 2020).
