Italy, on seedlings of Acca sellowiana, 2013, W.J. Duan (holotype HMAS 247163, dried culture, ex-holotype living culture CGMCC 3.18361 = LC 8150); ibid. LC 8151.
Conidiomata sporodochial, aggregated, semi-immersed or superficial, clavate, yellowish brown. Hyphae septate, branched, 3.5–5 μm. Conidia multicellular-phragmosporous, verrucose, subglobose-pyriform, brown, with a basal cell, 12.5–28 μm diam. Culture characteristics: Colonies on OA, 48–50 mm diam after 7 d, margin regular, covered by floccose aerial mycelia, dense, white to yellow, dark iron-grey near the centre, with a pale yellow halo near the margin, and a yellow concentre ring; reverse buff to yellowish brown. Colonies on MEA 50–55 mm diam after 7 d, margin regular, grey to pale yellowish green, with sparse white aerial mycelia; reverse concolourous. Colonies on PDA, 35–39 mm diam after 7 d, margin irregular, aerial mycelia floccose, yellow with a white margin, black near the centre; reverse salmon to saffron, with a yellow margin. Application of NaOH results in a yellow discolouration of the agar.
Phylogenetically, Epicoccum italicum formed a distinct lineage closely related to E. dendrobii. Morphologically, the two species could be distinguished in the length of epicoccoid conidia (12.5–28 μm in E. italicum vs. 11–19 μm in E. dendrobii), and the results of NaOH test (a yellow discolouration in E. italicum vs. negative in E. dendrobii).
