Russula hiemisilvae

Ciri dan struktur

Russula hiemisilvae is a rather robust, mild, annulate species with a greyish-red pileus, stipe with rose hue and ellipsoid spores with a reticulate ornamentation with spines up to 1.5 µm high, occurring in savannah woodlands. Growth habit: basidiomata in small groups. Pileus: medium-sized, 50–55 mm in diam., plane, slightly centrally depressed; margin even, striate up to 15 mm, regularly shaped, finely crenulate; cuticle smooth, radially fibrous, slightly shiny, peelable up to ½ of the pileus radius, colour near the margin pinkish-white (11A2), pale red (11A3) or greyish-rose (11B3), near the centre, dull red (11C3–4), greyish-brown (11D3) or greyish-red (11D4), sometimes with lighter spots. Lamellae: 5–6 mm wide, 7–8 lamellae present along 1 cm near the pileus margin, narrowly adnate, white, furcations, anastomoses and lamellulae absent; edges, concolourous. Stipe: 40–45 × 12–15 mm, cylindrical, sometimes narrowing towards the base, slightly bulging here and there; smooth to slightly rugose, with a fugacious white and dull red (11C3–4) rimmed annulus, white with a rose hue; cottony stuffed. Context: 1 mm thick at half pileus radius, white, unchanging when bruised, brittle, taste mild, odour inconspicuous; macrochemical reactions: guaiac after 8–10 seconds positive (++) on both stipe and lamellae surfaces, FeSO 4 rose, sulphovanillin negative, KOH discolouring red parts to yellow, phenol negative. Spore print: not observed, but probably white or cream. Spores: (8.3–)8.6–9–9.4(–9.9) × (7.3–)7.5–7.7–7.9(–8) µm (n = 30), Q = (1.08–)1.13–1.17–1.22(–1.26), subglobose to broadly ellipsoid; ornamentation of moderately distant amyloid spines [3–6(–7) in a circle of 3 µm diam.], 1.1–1.5 µm high, connected by abundant, distinct lines [3–6(–7) in the circle], forming a complete reticulum with regularly-shaped meshes, isolated elements absent; suprahilar plage small, inamyloid, without ornamentation, surrounded by small warts.
