Amphichorda cavernicola Z.F. Zhang & L. Cai, Fungal Diversity: 10.1007/s13225-020-00453-7, [67] (2020)

Index Fungorum number: 556419, Facesofungi number: FoF 08438;

Holotype: HMAS 248011.

Hyphae hyaline, septate, smooth-walled, 1.5–2.5 µm diam. Asexual morph Synnemata arising in the center part of colonies on OA or PDA with peptone, cylindrical with apical apex, tomentose, white. Conidiophores arising later[1]ally from hyphae, cylindrical, straight or slightly curved, occasionally branched, hyaline. Conidiogenous cells bone on conidiophores or mycelia, fusiform or ellipsoidal, straight or irregularly bent, 4.5–8.0 × 2.0–3.0 µm. Conidia holoblastic, solitary or clumped, unicellular, broadly ellipsoidal to sub[1]globose, smooth, hyaline, 2.5–4.0 × 2.0–3.5 µm (x̄ ± SD = 3.4 ± 0.36 × 2.8 ± 0.24 µm, n = 60). Chlamydospores and Sexual morph not observed.

Culture characteristics—Colonies on PDA attaining 9–15 mm diam. after 14 days, irregular, compact, extremely pli[1]cated and crack, cream-yellow (4A1) to seashell (30A2) i fruiting zone and tan (5A2) in aging zone, aerial mycelia sparse. Reserve compact and crack, cream-yellow (1A2) to brown from fruiting zone and tan (4E8) in aging zone. Colony on OA attaining 18–22 mm diam. after 14 days, dense, compact and plicated, margin radially striate with lobate edge, white to milk-white, with synnemata in center. Reserve pale yellow (4A2) with yellow-brown (4B8) mar[1]gin. Colonies on SNA slowly growing, attaining 9–13 mm diam. after 14 days, margin entire, white, mycelia sparse, with white hyphae body. Reverse white. Sporulation within 10 days on OA and SNA. Material examined: CHINA, Sichuan, Xingwen, Feng Cave, N28.186°, E105.148°, on bird faeces, May 2016, Z.F.
