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
