Figure Fig. 1 5-day-old colony on PDA Fig. 2 Diaporthe arengae. a. Conidiomata on WA supplemented with sterile rice grains. b, d. Conidia. c, e. Conidiogenous cells and conidia (Bars= 5 μm, unless otherwise specified)
Colonies Colonies on PDA attaining 51-, 60-, 0-mm at 24 °C, 28 °C and 37 °C after 5 days, margins irregular, reverse dark olivaceous.
Conidiophores Conidiophores hyaline, branched, cylindrical, arise from swollen pigmented cells, 10–45 × 2–4 µm.
Conidiogenous cells Conidiogenous cells phialidic, cylindrical, hyaline, 14–40 × 1–2 µm.
Conidia Alpha conidia fusiform, hyaline, often two-guttulate, 6–7 × 2–2.5 µm. Beta conidia hyaline, cylindrical to fusiform, 19–24 × 1–2(–2.5) µm.
Note Strain 13038 shares 100% identity in ITS region with the ex-type strain of Diaporthe arengae (CBS 114979, KC343034). WA amended with rice grains could induce sporulation.
