Subulicystidium parvisporum

Ciri dan struktur

The species with the smallest basidiospores known in the genus, 5.0–6.2 × 2.2–2.8 µm and allantoid, combined with rather small cystidia with regular delicate encrustation. Basidiomata annual, effused, resupinate, soft and fragile, arachnoid, thin, loosely adnate. Hymenophore smooth, finely velutinous due to numerous protruding cystidia, whitish. Margin thinning out, pruinose, adnate. system monomitic. All septa with clamps. Subiculum thin, with loosely interwoven richly branched hyphae 1.8–3 µm wide, thin-walled, hyaline and smooth. Subhymenium thin, with hyphae similar to those in subiculum but occasionally bearing slight amorphous hyaline encrustation. Cystidia subulate, 45–65 × 2.5–3 µm including encrustation, projecting up to 30 µm, without basal swelling, terminal or pleural, with thin hyaline cell wall and outer hyaline crystalline sheath covering the whole cystidium except the thin-walled, narrow, acuminate apex. Crystal protrusions on cystidium are low but clearly rectangular and arranged in longitudinal rows. Basidia suburniform to almost clavate, 10–15 × 4–5 µm, thin-walled, with 4 sterigmata and a basal clamp, occasionally with slight amorphous hyaline encrustation at the base. Basidiospores allantoid, often with a slight constriction in the middle part, L= (4.3)5.0–6.2(–6.8) µm, W=(1.8–)2.2–2.8(–3.0) µm, Q=(1.8–)1.9–2.6(–3.1), N=151/4, with minute apiculus, smooth, thin-walled, hyaline, occasionally with one or two oil drops, negative in Melzer’s reagent. Tolerance limits for basidiospore length, width and length to width ratio in S. parvisporum, based on 4 sequenced specimens, are provided in the Table 2.
