Russula sublaevis

Ciri dan struktur

Russula sublaevis is a species with medium-sized basidiomata, a bright yellow pileus, white stipe, mild taste and cream-coloured spore print. Microscopically, the small subglobose spores with a very low ornamentation are noticeable. Growth habit: solitary or in groups of two. Pileus: medium-sized, 50–70 mm in diam., slightly convex to plane, centrally with a low shallow depression; margin even, finely striate up to 15 mm, regularly shaped; cuticle smooth, pruinose all over, under a magnifying glass with fine, whitish areolae, peelable up to ¾ of the pileus radius, colour yellow to bright yellow (3A2), becoming paler with age, near the centre sometimes slightly paler or darker. Lamellae: 5–6 mm wide, 8–9 lamellae present along 1 cm near the pileus margin, adnexed, at first white, then becoming pale cream, furcations and anastomoses absent, sometimes with dispersed lamellulae; edges entire, concolourous. Stipe: 35–45 × 8–10 mm, cylindrical, somewhat bulging here and there, smooth to slightly rugose, annulus absent, white; cottony stuffed, cavernate, with 2–3 distinct chambers. Context: 4–5 mm thick at half pileus radius, white, unchanging when bruised, brittle, taste mild, odour inconspicuous. Macrochemical reactions: guaiac after 8–10 seconds weakly positive (+) or negative (-) on stipe and positive (++) on lamellae surfaces; FeSO 4 salmon orange, sulphovanillin negative; KOH negative; phenol negative. Spore print: cream (IIc). Spores: (5.4–)6–6.3–6.7(–7.1) × (4.5–)5.1–5.4–5.6(–6) µm (n = 90), Q = (1.06–)1.12–1.18–1.24(–1.31), subglobose to broadly ellipsoid; surface almost smooth, ornamentation very inconspicuous, composed of very dense, weakly amyloid pustules and crests hardly visible under light microscope, ornamentation approx. 0.1 µm high as estimated by SEM, abundantly connected by fine lines forming a complete reticulum; few scattered isolated warts only visible by SEM; suprahilar plage small, inamyloid, partially covered by even lower ornamentation only visible by SEM.
