Mycena hygrophoroides

Ciri dan struktur

Pileus concave with slight pruinose. Lamellae distant. Stipe with dense white fibrils and swollen base. Acanthocysts forming two types. Caulocystidia long-elliptic with conical excrescences, up to 120 μm long. Pileus 1.5–2.5 mm in diam., campanulate to hemispherical, applanate or slightly concave at centre, white with greyish shade (6B1), shallowly sulcate, translucent-striate, slightly pruinose, pubescent. Context white, thin and very fragile. Lamellae distant, sparse, white, concolorous with the sides. Stipe 4.5–8.2 × 0.5–0.8 mm, cylindrical, hollow, fragile, pure white (5A1) with a greyish (5B1) base, covered with dense white fibrils, base swollen and not forming basal disc, hirsute. Odour and taste indistinctive. Basidiospores (6.9-)7.2-8.9(-9.3) × (5.3-)6.4-6.7(-7.1) μm, Q=1.2–1.5, Qav=1.31, broadly-ellipsoid, hyaline in water and 5% KOH, amyloid, smooth. Basidia 15–21 × 7–9 μm, 4- or 2-spored, clavate, hyaline. Cheilocystidia 23–37 × 19–28 μm, subglobose, sphaero-pedunculate to utriform with numerous sharp spines, thin-walled and hyaline, inamyloid. Pleurocystidia absent. Pileipellis hyphae 3–9 μm wide, dextrinoid; cherocytes absent; a cutis overlaid by elements of universal veil, not in chains; acanthocysts forming two types, pyriform to vesicular, 13–29 × 11–24 μm, clavate to ovoid or obovoid, 29–42 × 14–20 μm, inamyloid. Hyphae of the stipitipellis 3–7 μm wide, smooth, dextrinoid; caulocystidia abundant, clavate, long-elliptic, 32–122 × 8–11 μm, with numbers of conical spines, inamyloid. Clamps present in all tissues.

Habitat dan peran ekologis

Mycena hygrophoroides could be considered to be a member of Hemimycena Singer owing to the tiny basidiomata and sparse lamellae, but the absence of a basal disc, amyloid spores and spinulose cheilocystidia, acanthocysts and caulocystidia are diagnostic characters for M. hygrophoroides, which should be placed in Mycena sect. Amparoina stirps Alphitophora. Mycena acanthophila J.C.Zamora&Català, of which the holotype was collected from Spain growing on dead branches of Leguminosae, most resembles M. hygrophoroides, but differs in having a yellow pileus, smaller cheilocystidia (13.5–22 × 8.5–12 μm) and diverse caulocystidia (Zamora and Català 2012). Mycena depilata, a species of stirps Alphitophora, shows some morphological similarities to M. hygrophoroides in possessing white and tiny basidiomata, distant lamellae (L = 7–9) and globose-pedicellate acanthocysts with hyaline contents. However, M. depilata differs in producing ellipsoid spores (Q = 1.64 ± 0.11), broadly clavate cheilocystidia and shorter caulocystidia (16–50 × 5–16 μm; Singer 1989). Mycena hemitrichialis is difficult to distinguish from M. hygrophoroides, but M. hemitrichialis has free to subfree lamellae, longer caulocystidia (100–300 × 5–15 μm) and ellipsoid spores (Singer 1989).
