Hebeloma marginatulum

Ciri dan struktur

Cap 1.1–4.7 cm in diameter, convex to umbonate, occasionally papillate, margin smooth, tacky when moist, sometimes hygrophanous, uniformly colored or variably bicolored, at center ochraceous or dark olive buff to brownish olive or umber to sepia to fuscous or dark brick, at margin cream to grayish or pinkish buff to ochraceous or dark olive buff to umber, sometimes very thin; with remains of universal veil, partial veil present. Lamellae initially very pale clay, later clay, emarginate, maximum depth 3–8 mm, number of lamellae {L} 32–45, droplets absent, white fimbriate edge usually weakly present. Stem 1.4–4.5(–6.5) × 0.3–0.7(–0.8) cm, pale sordid ochraceous downwards, cylindrical to slightly clavate, fibrillose, whitish pruinose to floccose at apex. Context watery gray brown in cap, in stem lighter, firm, stem interior stuffed, later hollow, occasionally with superior wick, stem flesh usually discoloring from base. Smell usually raphanoid, but sometimes no smell detected. Taste bitter. Spore deposit clay buff to dark olive buff to grayish brown to brownish olive or umber. Spores shape ellipsoid, occasionally amygdaloid or ovoid, on ave. 10.0–13.0 × 5.5–7.5 µm, ave. Q = 1.6–1.9, grayish yellow, rarely guttulate, almost smooth (O1 (O2)), perispore not loosening (P0), not or indistinctly dextrinoid (D0 D1). Basidia (28–)30–34(–37) × 7–9 µm, ave. Q = 4–4.5, mostly four-spored. Cheilocystidia lageniform, ventricose or occasionally cylindrical or clavate, occasionally with characteristic apical thickening, bifurcate, geniculate and septate (sometimes clamped), on ave. 44–69 × 5–7 (apex) × 4.5–5 (middle) × 7.5–10.5 (base) µm, ratios A/M = 1.1–1.4, A/B = 0.53–0.81, B/M = 1.55–2.33.

Habitat dan peran ekologis

Hebeloma marginatulum is widespread and, apparently, one of the most common Hebeloma species in Greenland (11.1% of the collections, see Table 3), also common in other parts of North America and present in parts of Europe (Beker et al. 2016; Cripps et al. 2019). It is a truly arctic-alpine species hardly found outside these areas. Arctic-alpine. Forty-five collections with many hosts. Twenty collections with Salix (S. herbacea 9, S. glauca 6, S. arctophila 3 and S. arctica 2), two with Betula pubescens var. pumila, two with Betula sp. and three with Dryas octopetala and D. integrifolia (as always, other potential hosts may have been nearby). In the Rocky Mountains, it is also common, found with Salix arctica, S. reticulata and S. planifolia (Cripps et al. 2019). Beker et al. (2016) have S. herbacea and S. polaris as the main hosts. Hebeloma marginatulum occurs on a variety of soil types seemingly without specific preferences.
