Anamika indica
Anamika indica K.A. Thomas, Peintner, M.M. Moser & Manim. 2002, in Thomas et al., Mycological Research, 106(2), 245-251 (2002).
Etymology: The specific epithet refers to the provenance.
Diagnosis: Pileus (Figure 1) 9±30 mm diam, hemispherical, conicoconvex or convex when young, becoming plano-convex to applanate when mature, sometimes with a small depression at the centre; non-hygrophanous; surface pale orange (5A3), greyish orange (5B4), light brown (6D6, 6D7), brownish orange (7C6) or brown (7D7) towards centre, unicolorous or mostly fading towards the margin to orange-white (5A2), pale orange (5A3) or greyish orange (6B3, 6B4), smooth, glabrous, not translucently striate, slightly sticky when moist; margin incurved and entire when young, becoming decurved and fissile with age. Context pale brown. Lamellae adnate, initially whitish, becoming pale orange (5A3), greyish orange (6B3, 6B4), brownish orange (6C4), or light brown (6D4, 6D5), sometimes brown (7E6, 6E7) on maturity, subcrowded to close, up of this fungus. to 5 mm wide, with lamellulae of 3–4 lengths; edge concolorous with the sides or slightly paler, fimbriate under a lens. Stipe 15–55×2–6.5 mm, central, terete, almost equal
or enlarged towards both ends, at times tapering apically, solid, sometimes fistulose; surface off-white,
orange white (5A2), or light orange (5A3) towards the apex, brown or light brown (6E6) towards the base, sometimes weakly longitudinally striate, or with minute longitudinal cracks, slightly furfuraceous, at times with a cortina when young, which often leaves inconspicuous annular remnants. Odour not distinctive. Spore deposit brown (7E5, 7E6).
Basidiospores (Figures 2–3) amygdaliform to sublimoniform, 10–14×6.5–8.5 µm (Q=1.40–1.75, av.=1.53), acyanophilous, in cotton blue inner wall layers reddish, epitunica in Melzer slightly bluish, thick-walled, with cavernous type of ornamentation, visible already in light microscope (oil immersion) after staining with Melzer, cotton blue or cresyl blue, with a conspicuous callus, without germ-pore. Basidia (Figure 4) 25–35×7.5–10.5 µm, with a median constriction, 4- or rarely 2- spored; sterigmata up to 6–5 µm long. Lamella-edge with numerous cheilocystidia (Figure 5), 11.5–62.5×4.5–16.5 µm, versiform: clavate, pedicellate-clavate, uteriform or fusoid, frequently with a subcapitate, mucronate or rostrate apex, thin-walled, hyaline. Pleurocystidia (Figure 6) 17.5–42.5×5–12 µm, scattered, versiform and similar to cheilocystidia in shape, thin-walled, hyaline. Hymenophoral trama regular, hyphae 1.5–15 µm wide, closely packed, thin-walled, colourless. Pileus trama interwoven, hyphae 1.5–16.5 µm wide, thin-walled, colourless. Pileipellis (Figure 7) an epicutis, hyphae 1.5–10 µm wide, repent thin-walled, with colourless or brownish incrustation. Hypocutis distinct and well developed, subcellular, composed of swollen, versiform elements including many isodiametric ones, 10–47×6.5–13 µm, thin-walled, with coarse, brown pigment encrustation. Pileus rim bearing numerous cystidia indistinguishable from cheilocystidia. Stipe trama composed of 2–14 µm wide, parallel hyphae, thin-walled, hyaline. Stipitipellis a cutis, hyphae 1– 7.5 µm wide, thin-walled, hyaline. Caulocystidia (Figure 8) 20–77.5×4.5–15 µm, versiform, similar to cheilocystidia in shape, thin-walled, hyaline, occurring either in small clusters or scattered. Clamp connections present in all tissues.
