Colonies grown from single conidia on Difco PDA 75–85 mm diam after 10 d for most isolates, the ex-holotype culture of G. cingulata var. migrans 48–49 mm diam. Aerial mycelium cottony, grey, dense, or in some isolates with dark stromatic masses and associated orange conidial ooze showing through mycelium from agar surface; in reverse agar with pinkish-orange pigments (6B4–7B4), irregular scattered black spots, and variable levels of development of overlying dark grey to green-grey pigments (4C2–5D4), these sometimes in discrete sectors. See notes below about a divergent growth form single ascospore cultures from perithecia in culture. Conidia form on dark-based acervuli, (12–)16–19.5(–29) × (4.5–)5(–8) µm (av. 17.8 × 5.1 µm, n = 214), cylindric, straight, apex rounded, often tapering slightly towards the base. Appressoria typically cylindric to fusoid in shape, deeply lobed. Perithecia numerous, forming tightly packed clumps, individual perithecia globose, small, about 250 µm diam, with a short ostiolar neck. Asci 55–100 × 10–12 µm, 8–spored. Ascospores (13.5–)17.5–20(–24) × (4–)4.5–5(–6.5) µm (av. 18.8 × 4.8 µm, n = 121), gently curved, tapering to quite narrow, rounded ends, widest point usually towards one end of the spore.
Geographic distribution and host range: Known from Australia, Germany, New Zealand, and South Africa. Both host and geographic range of the isolates we accept in C. kahawae subsp. ciggaro are broad. Genetic identification: ACT, CAL, CHS-1, GAPDH, TUB2, SOD2, and ITS sequences match those from C. kahawae subsp. kahawae. The two subspecies can be distinguished by GS sequences. Collectively, the two subspecies can be distinguished from all other species using ITS sequences alone.
Holotype: Australia, on Olea europaea, coll. V. Sergeeva UWS124, 1989, PDD 102232; ex-type culture ICMP 18539
