Diaporthe amygdali

Ciri dan struktur

Associated with leaf spot disease of Alnus nepalensis. Teleomorph: Undetermined. Anamorph: Conidiomata formed on PDA pycnidial, scattered, erumpent, subglobose, dark brown, 700–2250 μm diam. Conidiophores indistinct, usually reduced to conidiogenous cells. Conidiogenous cells cylindrical, attenuate towards the apex, hyaline, phialidic, 16.5–34 × 1.5–3 μm. Alpha conidia not observed. Beta conidia aseptate, hyaline, smooth, guttulate, filiform, tapering towards both ends, straight or slightly curved, (27.5–)30–35(–40.5) × 1.5–2 μm (x̄ = 32.6 × 1.6 μm, n = 50), L/W = 15.8–23.1. Gamma conidia not observed. Colonies on PDA at 25 °C are flocculent, forming concentric zones with undulate margins, initially white, turning pale brownish, and reaching a diameter of 90 mm after 10 d, developing dark brown conidiomata with white conidial masses after 25 d. Colonies on MEA at 25 °C are flat, spreading, with a smooth entire margin, white, reaching a diameter of 80 mm after 20 d, sterile. Colonies on SNA at 25 °C are flat, spreading with a feathery margin, white, reaching 80 mm in diameter after 20 d, sterile.
