Name
Apiospora coryli S.J. Li & C.M. Tian sp. nov. – Wikispecies link – Pensoft Profile
Type
China, Shanxi Province: Ankang City, Huoditang Forest Farm, on dead plant culms of Corylus yunnanensis, 16 July 2021, R. Yuan & S.J. Li, holotype BJFC-S1920, ex-type living cultures CFCC 58978, CFCC 58979.
Etymology
Named after the host from which it was isolated.
Description
Asexual morph: Derived from sporulated cultures on PDA, hyphae hyaline, branched, septate, 1.1–5.2 µm diam. Conidiophores reduced to conidiogenous cells. Conidiogenous cells erect, aggregated in clusters on hyphae, hyaline to pale brown, smooth, doliiform to clavate or lageniform, 2.6–10.6 × 2.1–5.8 µm, mean (± SD): 5.5 (± 2.4) × 3.4 (± 1.1) µm (n = 50). Conidia brown to dark brown, globose to subglobose, oval or irregular, smooth to finely roughened, guttulate, usually with a longitudinal germ slit, 7.4–18.4 × 6.2–12.5 µm, mean (± SD): 10.8 (± 1.7) × 9.4 (± 1.3) µm, L/W = 0.8–1.6 (n = 50). Sexual morph: Undetermined.
Culture characteristics
On PDA, colonies circular, flat, entire margin, thick and cottony, concentrically spreading with aerial mycelium, margin regular, reddish-brown pigment diffused into medium, surface dark yellowish-brown, reverse dark reddish-brown to yellowish-brown from the centre, mycelia white to pale umber, sporulation on hyphae, reaching 9 cm in 7 days at 25 °C.
Notes
Strains of A. coryli constitutes a distinct clade, but there is poor support value in concatenated gene trees (Fig. 1). The most prominent distinguishing characteristic is the production of reddish-brown pigments on the culture medium.
