Typhrasa polycystis

Ciri dan struktur

Differs from Typhrasa gossypina by its smaller spores (7.1–8.2 × 4.3–5.1 μm). Pileus 20–35 mm, extending hemispherically to expanded, plane with or without umbo, surface with slightly ridge-like folds or smooth, hygrophanous, brown (7D6–7C6), pale brown (6B6–6C6) at the margin. Veil distinct, fibrous or fluffy, white (7C1), markedly appendiculate at margin, falling off easily. Context thin and fragile, hygrophanous at pileus, about 3.0 mm at the centre. Gills 4.0–5.0 mm broad, moderately close, pale cinnamon (6C6–6D5) with a white (6C1) edge, adnexed. Stipe 30–45 mm long, 5.0–8.0 mm thick, white (6C1), hollow, pulverulent at apex, with fibrils and fluffy from pellicular veil remnants below, falling off easily. Spores (6.9)7.1–8.2 × (4.2)4.3–5.1(5.2) μm, Q = (1.4)1.5–1.8(1.9), ellipsoid to oblong-ellipsoid, profile flattened on one side, 4.1–5.0(5.2) μm broad, smooth, reddish-brown (8C5–8C6) in water, yellow-brown (7D6–7D7) in 5% KOH or 10% NH 3 ·H 2 O, becoming darker (7E4–7F4) in 5% KOH, germ pore small and indistinct, 1–2 guttulate, inamyloid. Basidia 21–24 × 7.5–8.5 μm, 4-spored, clavate, hyaline. Pleurocystidia 55–81(87) × 11–17(18) μm, variously shaped, often fusiform and lageniform, with rostrum; rarely fusiform with subacute to acute apex or cystiform with rostrum, with one or two large internal oily drops, oily drops colourless and distinct or indistinct in 5% KOH, glassy-yellow (5B6–5B7) and very distinct in Melzer’s Reagent. Cheilocystidia (24)30–54(58) × (9)10–15(16) μm, similar to pleurocystidia, abundant, rarely mixed with pyriform or clavate cells. Trama of gills consisting of parallel hyphae.
