Hebeloma alpinum

Ciri dan struktur

Cap 1.7–7.3 cm, convex to umbonate or broadly umbonate; margin smooth, often involute, sometimes crenulate or serrate, tacky when moist, not hygrophanous, almost unicolored, occasionally bicolored, at center cream to pink buff to dark olive buff brown or yellowish brown to brownish olive or umber to sepia, clay buff or cinnamon, margin cream to pink buff or clay buff, sometimes very thin, universal veil absent, partial veil absent. Lamellae whitish, later light gray brown, then sordid brownish, number of lamellae {L} 40–72, emarginate, 0.3–0.9 cm broad, exuded drops usually visible with naked eye, but sometimes absent, with white fimbriate edge. Stem 1.5–5.0 × 0.4–1.2 cm, whitish fimbriate-pruinose in the entire length, later downwards slightly sordid ochraceous, ochre-yellowish or pale brown, base cylindric to clavate, rarely bulbous, occasionally tapering, pruinose to floccose particularly at apex, when fresh with droplets. Trama firm, stem with a stuffed interior, occasionally becoming hollow with age, not discoloring. Smell usually raphanoid, occasionally of cocoa or absent. Taste mild to weakly bitter. Spore deposit dark olive buff, brownish olive to clay buff. Spores amygdaloid to limoniform, on ave. 9.5–15 × 5.5–8.5 µm, ave. Q = 1.4–2.2, yellow brown to brown, sometimes guttulate, papillate, sometimes very strongly, almost smooth to weakly ornamented (O1 O2 (03)), perispore not or somewhat loosening (P0 P1), indextrinoid to weakly dextrinoid (D0 D1 D2). Basidia 28–40(–45) × 8–12 µm, Q = 3–4.3, mostly four-spored. Cheilocystidia mainly clavate-stipitate or spathulate-stipitate, occasionally slenderly clavate or clavate-lageniform, occasional apically thickening, rostrate, septate or sinuate, on ave. 40–71 × 7–10 (apex) × 3.5–5 (middle) × 3.5–6 (base) µm, ratios A/M = 1.6–2.7, A/B = 1.5–2.7, B/M = 0.9–1.2.

Habitat dan peran ekologis

Hebeloma alpinum is one of the five most often recorded Hebeloma species in Greenland, with 36 records (almost 10%) of those considered here. This is in good accordance with Beker et al. (2016), who pointed out that this is “the most common Hebeloma species we have collected in arctic/alpine areas”. It occurs all over Greenland, from Sermiliarsuk in the south (61.6°N) to Zackenberg (74.5°N) and V. Clausen Fjord (77.5°N) in the north. In Constable Pynt in East Greenland in 2017 it was the most common of all mushrooms. In Europe, it is known from the major mountain ranges (the Alps, the Pyrenees, the Tatras, the Carpathians, Black Mountains in Montenegro), from supraboreal Iceland (Beker et al. 2016). It has been reported in North America from the Rocky Mountains (Montana, Cripps et al. 2019). Arctic-alpine, boreal and subarctic. The 36 collections are all from calcareous localities. The preferred host is Dryas integrifolia but possibly also D. octopetala. When these two occur together as in NE Greenland, they often hybridize, and can be difficult to identify. Only a few collections are reported with other hosts like Salix arctica, S. herbacea, Betula pubescens, B. nana and even Bistorta vivipara.
