Wardomycopsis dolichi
Wardomycopsis dolichi Z.F. Zhang & L. Cai, sp. nov.
Index Fungorum number: 557750, Facesofungi number: FoF 08459; Fig. 44
Etymology: Referring to its long conidiophore.
Holotype: HMAS 247998.
Hyphae hyaline to pale olive, septate, smooth or fnely verrucose, thick-walled, 1.5–3.5 µm diam., sometimes swollen, up to 7.0 µm diam. Asexual morph Conidiophores cylindrical or long ellipsoidal, septate, branched 1–3 times, smooth, hyaline. Conidiogenous cells solitary on aerial hyphae, or in whorls of 1–3 at apex of conidiophores, ellipsoidal or ampulliform, hyaline, 3.5–7.5 × 2.5–4.0 µm. Conidia mostly borne from conidiogenous cells, occasionally observed on aerial hyphae directly, ellipsoidal or clavate, thick-walled, brown, 4.5–7.0 × 2.5–4.0 µm (x̄ ± SD = 5.7 ± 0.72 × 3.3 ± 0.33 µm, n = 50), with truncated base and median longitudinal germ slit. Sexual morph not observed. Culture characteristics—Colonies on PDA attaining 24–28 mm diam. after 3 weeks, compact, slightly plicated, margin entire, white at margin, black at center. Reverse cream-yellow (30A2) to black. Colonies on OA attaining 28–34 mm diam. after 3 weeks, ulotrichy, low convex, margin entire, white to gray (27E1) from margin to center. Reverse white to pale gray (25B1). Colonies on SNA attaining 24–29 mm diam. after 3 weeks, ulotrichy, margin crenate, beige (2A2) to pale olive (30D8). Reverse beige (2A2) to dark olive (30E8). Sporulation within 15 days on OA and SNA.
Material examined: CHINA, Guangxi, Guilin, E’gu Cave, N 24.942°, E 110.511°, on soil, May 2016, Z.F. Zhang, HMAS 247998 (holotype designated here), ex-type living culture CGMCC3.19310 = LC12503; ibid., LC12504.
Notes: Our strains clustered within Wardomycopsis and formed a distinct clade with high support value based on the multi-locus analysis (Fig. 37). W. dolichi is phylogenetically allied to W. longicatenata Z.F. Zhang, F. Liu & L. Cai, but difers in its wider conidiogenous cells (2.5–4.0 µm vs. 1.5–2.5 µm) and conidia (2.5–4.0 µm vs. 1.5–2.5 µm), color on PDA and SNA media, and the absence of sexual morph, which is observed in W. longicatena.
