Mycena miscanthi

Ciri dan struktur

Growing on dead stem of Miscanthus. Pileus sparsely pruinose. Basidiospores cylindric. Cherocytes absent. Acanthocysts forming two types. Caulocystidia sphaero-pedunculate covered with spines. Clamps present. Pileus 3.5–7.8 mm in diam., hemispherical, broadly conical to convex, occasionally ± centrally depressed when young, sulcate, translucent-striate, pure white, pubescent to inconspicuously puberulous, margin nearly plane, undulate. Context white, thin, very fragile, about 1.0 mm thick at centre. Lamellae narrowly adnate or adnexed, off-white, concolorous with the sides. Stipe 26–38 × 0.5–1.0 mm, pure white, central, terete, hollow, equal, surface covered with slight white pubescent, base swollen but not discoid, pruinose. Odour and taste not distinctive. Basidiospores (6.2-)6.7–8.6(-9.1) × (3.1)3.3–4.2(4.5) μm, Q=1.8–2.3, Qav=2.07, cylindric to narrow-ellipsoid, hyaline, guttulate, thin walled, amyloid. Basidia 18–24 × 6–9 μm, clavate, hyaline, 4-spored. Cheilocystidia 13–26 × 9–14 μm, abundant, lageniform, utriform or sphaero-pedunculate, with short and conical spines. Pleurocystidia absent. Pileipellis hyphae 3–8 μm wide, strongly dextrinoid; cherocytes absent; universal veil composed of acanthocysts, forming two types, pyriform, vesicular or clavate, 12–32 × 10–17 μm, inamyloid. Hyphae of the stipitipellis 2–8 μm wide, with coarse excrescences, 0.9–2.8 × 0.5–0.9 μm, strongly dextrinoid; caulocystidia abundant, elliptic, utriform, sphaero-pedunculate, 15–37 × 7–15 μm, with conical or cylindrical spines inamyloid. Clamps present in all tissues.

Habitat dan peran ekologis

Growing on dead stem of Miscanthus. Pileus sparsely pruinose. Basidiospores cylindric. Cherocytes absent. Acanthocysts forming two types. Caulocystidia sphaero-pedunculate covered with spines. Clamps present. Solitary to scattered on dead stem of Miscanthus. The distinctive features of Mycena miscanthi include a white, granulose pileus, a pubescent stipe without forming a basal disc, narrow-ellipsoid spores, two types of acanthocysts and growth on dead stems of Miscanthus species. In combination, these features support the placement of M. miscanthi in sect. Amparoina stirps Alphitophora. Similar to M. miscanthi, M. alphitophora and M. depilata produce pure white basidiomata, cylindric spores and sphaero-pedunculate and spinulose cheilocystidia (Desjardin 1995; Aravindakshan and Manimohan 2015). However, the two types of acanthocysts and longer caulocystidia can be used to distinguish M. alphitophora and M. depilata from M. miscanthi (Desjardin 1995). Mycena hemitrichialis is closely allied to M. miscanthi, but differs in producing caulocystidia up to 400 μm in length that lack spinulae or with a few spinulae in the upper half (Singer 1989). Mycena distincta, which was originally described as M. alphitophora var. distincta, was elevated to species level by Manimohan and Leelavathy (1989).
