Hygrophorus griseodiscus

Ciri dan struktur

Hygrophorus griseodiscus is distinguished from H. brunneodiscus by the greyish pileus with a darker grey pileus disc and larger basidiospores measuring (7)8–10(10.5) × (4)4.5–6(6.5) µm. Pileus 20–45 mm broad, convex, obtusely umbonate at disc, grey to light grey (1C1, 1D1), medium to dark grey or olive grey (1E1, 1F1–4) at disc, white to pale grey (1B1) at margin, glutinous when wet; margin even, slightly involuted to extended. Lamellae emarginate with decurrent tooth or subdecurrent, white, thick, subcrowded, unequal, with 1–3 lamellulae between two entire lamellae. Stipe 40–70 × 4–6 mm, cylindrical, white to pale grey (1B1), covered with transparent glutinous materials when wet. Context slightly thick, white. Basidiospores (7)8–10(10.5) × (4)4.5–6(6.5) µm [mean length = 9 µm, mean width = 5.2 µm], Q = 1.4–2.1, Qm = 1.74, ellipsoid, oblong to subcylindrical, smooth, hyaline. Basidia 29–56.5 × 7–11 µm, Q = 3.05–6(6.9), Qm = 4.39, clavate to cylindrical, thin-walled, 4-spored, with sterigmata up to 6 µm long. Pileipellis an ixotrichoderm, covered with a gelatinous layer; hyphae thin-walled, 2.5–6 μm wide. Hymenophoral trama divergent, composed of septate, thin-walled and cylindrical hyphae; hyphal cells 5.5–20 μm in width, hyaline. Clamp connections present.
