Hierarchy: Basidiomycota, Agaricales , Psathyrellaceae

Specimens examined: KOREA, Seoul, Jongmyo shrine, 37°34 ʹ 24 ʺ N, 126°59 ʹ 47 ʺ E, 12 Aug 2015, Hae Jin Cho, Hyun Lee, Young Woon Lim, SFC20150812-15 (GenBank accession No. MF 445222), on the ground of deciduous forest .

Pileus 10-25 mm, first conical to convex, becoming applanate with central depression, hygrophnous, pruinose, plicate-striate, veil absent, margin crenulate, orange white (5A2) to brownish orange (6C5). Lamellae free to adnexed, close, concolorous with pileus, black in age, lamellulae present. Stipe 35-75 × 1-2 mm, smooth, filiform, hollow, white.

Basidiospores 9.7-10.4-11.2 × 6.9-7.5-8.1 μm, Q = 1.28- 1.38-1.54, ellipsoidal, germ-pore central, dark brown. Basidia 22.9-27.9-36.7 × 9.0-9.8-10.8 μm, clavate. Cheilocystidia not seen. Pleurocystidia 22.8-29.3-32.3 × 8.7- 9.5-10.5 μm, cylindrical to slightly cymbiform with acute apex. Pileipellis hymeniform, dermatocystidia 117.4-119.3-140.9 × 7.3-8.2-8.9 μm, lanceolate with thick walls.

Remarks: Parasola setulosa has thicker cell walls than those of its sister species, P. auricoma . Parasola setulosa is similar to P. mirabilis in morphology but P. mirabilis has smaller basidiospores (8.5-10.6 × 5.9-6.6 μm) ( Nagy et al., 2010).
