Inocybe athenana Bandini, B. Oertel & U. Eberh. ( Fig. 5 )

Mycologia Bavarica . 20:13-101 (2020)

Isotype collection DB15-6-19-2:— Basidiospores (7.7)8.2–9.6(11.2) × (4.5)5.1–6.0(6.4) μm, Q = (1.3)1.6–2.0(2.1), in average 8.9 × 5.5 μm (n = 100) smooth, asymmetrical, from ellipsoid to subamygdaliform, at most without conical apex. Basidia 24–32 × 7–12 μm, tetrasporic, clavate. Pleurocystidia (53)58–72(77) × (16)18–28(32) µm, on average 65 × 23 µm (n = 30) Q = (2.1)2.2–3.6(3.7), abundant, fusiform or ventricose-clavate, thin-walled up to 1.7 μm, with apical crystals; ammonia reaction positive. Cheilocystidia similar to pleurocystidia. Paracystidia 15–28 × 6–17 μm, subcylindric to clavate, abundant. Caulocystidia 48–72 × 12–19 µm, on average 59 × 15 µm (n = 15) slender in respect to the hymenial cystidia, present all over the stipe surface, mixed with some cauloparacystidia. Clamp connections present in all tissues.
