| Characteristics |
Lesions commonly present on leaves, stems, peduncles and fruits, causing discolouration of the tissues and deformation of the attacked organs. Down whitish, consisting of scattered conidiophores to dense, felt-like. Haustoria lobate, up to 22 μm long, up to 10 μm wide, filling the host cell partly to almost completely. Conidiophores colourless, stout, straight, (178–)216.6–254.7–292.8(–400) μm long (n = 60); trunk mostly straight, (70–)120–205(–350) μm long (n = 65), variable in width, 8–14 μm wide below the first branch, 9– 15 μm wide above the base, mostly with somewhat swollen base up to 18 μm wide; callose plugs mostly absent but very rarely present near the base; branching upper part monopodially or sub-dichotomously branched 5–7 times. Ultimate branchlets in pairs or rarely single, flexuous to sigmoid, (9.1–)10.7–12.8–15.0(–16.5) μm long, (1.4–)1.5–1.9–2.2(–2.5) μm wide at the base (n = 30), apex obtuse. Conidia hyaline, subglobose to broadly ellipsoidal, (13.8–)15.2–16.4–17.6(–18.8) μm long, (12.5–)12.7–13.5–14.2(–15.5) μm wide, l/w ratio (1.10–)1.16–1.22–1.28(–1.35) (n = 30), greatest width median, base and tip round; pedicel absent in most conidia but a scar visible at the point of attachment; producing germ tubes. Resting organs oogonia globose to irregular, golden or pale yellowish (43–)48.8–55–61.3(–64) μm diam. (n = 50), wall mostly smooth, 2.5–7 μm thick; oospores plerotic to aplerotic, globose, (23–)28.6–32–35.3(–37) μm diam. (n = 50), wall smooth, 2.5–3.5 μm thick. |
