Figure | Fig. 1 5-day-old colony on PDA Fig. 2 Bionectria pseudostriata. a–d. Conidiophores and conidia. e. Conidia (Bars= 5 μm, unless otherwise specified) Fig. 3 Maximum-likelihood (ML) tree obtained from aligned ITS, TUB2 sequence of the Bionectria subgen. Bionectria. |
Colonies | Colonies on PDA attaining 36-mm diam. after 5 days at 25 °C, cottony, azonate, white to pale yellow, producing diffuse yellow pigment. |
Sporodochia | Sporodochia produced on WA, OA after 7 days, subhyaline. |
Conidiophores | Conidiophores erect, hyaline, thick-walled, 2.5–4.5 µm wide, simple or with 1–2 adpressed lateral branches at the upper parts of conidiophore, each terminating in 1–4 verticillately arranged phialides; or branched in whorls of 3 terminally, which 1–2 of them often turning into solitary phialides. Sporodochial conidiophores branched repeatedly, verticillately, in whorls of 3–7, each terminating in 3–5 verticillately arranged phialides. |
Conidiogenous cells | Conidiogenous cells phialidic, hyaline, cylindrical, tapering towards the apex, with a short collarette, 16–23 × 2–3 µm. |
Conidia | Conidia ellipsoidal to obovoid, hyaline, straight or slightly curved, 4–6.5 × 2.5–4 µm. |
Note | Strain 13022 shares 99.81%, 97.00% identities in ITS, TUB regions respectively with the isotype strain of Bionectria pseudostriata (CBS 120.87; MH862056, AF358184).
Schroers (2001) reported that CBS 120.87 formed immature perithecia on OA which was not observed in strain 13022. |
Pathogenicity | Unknown. This species was originally discovered on bark of woody plants. |
Specimens examined | Taiwan, Tainan City, rice grains (cultivar Tainan 11), Dec 2012, Jie-Hao Ou, 13022 |
