Original description (Zhang, R.; Yang, H.L.; Sun, G.Y.; Li, H.Y.; Zhuang, J.L.; Zhai, X.R.; Gleason, M.L. 2009, Mycotaxon 110: 481) Strelitziana mali Rong Zhang & G.Y. Sun, sp. nov. Figs. 2-3 MycoBank MB 515170; GenBank FJ917556 Isolate QX01 was obtained in China from apple (Malus ×domestica), where it forms mycelial mats with sclerotium-like bodies on the fruit surface. The colony diameter after 1 month on PDA at 25°C reached 24 mm with even margins and smooth, felty aerial hyphae; colony centers are purplish gray and outer zones pale white. Hyphae are hyaline to brown, ramose, septate with aerial hyphae 2-3 µm diam. and submerged hyphae inflated, 3-5 µm diam. Conidiogenous cells terminal, pigmented, thinner than the conidia. Conidia hyaline, thin walled, solitary, fusiform to long obclavate, (12-)35-60(-100) x 7(-35) µm, (2-)5-10-septate. Microcyclic conidiation is present in culture (Fig. 2). Scanning electron microscope studies showed that conidiogenous cells were erect, solitary, arising from aerial and submerged mycelium, subcylindrical, straight to geniculous-sinuous, terminal, frequently constricted, abscising irregularly or regularly, and produced by a hypha that was thicker than the conidiogenous cell. Conidiogenesis is rhexolytic with remnants of the separating cell clearly visible on both the conidiogenous cell and conidia. Conidia produce secondary spores; hypha and/or conidia are often anastomose (Fig. 3).
