Other specimens examined: Australia, Queensland, Brisbane, on Carica sp., coll. J.H. Simmonds 16347A2 (ICMP 1780, dried culture stored as PDD 28797); Queensland, Home Hill, on Persea americana, coll. L. Coates 22516, Feb. 1983 (ICMP 12564). Fiji, on Coffea sp. berry, coll. R. Gounder, Apr. 1988 (ICMP 18705).
Colonies grown from single conidia on Difco PDA 62–74 mm diam after 10 d, aerial mycelium either dense, cottony, uniform, grey, or with aerial mycelium lacking, towards centre of colony with numerous, small acervuli with dark bases and orange conidial ooze; in reverse cultures with copious aerial mycelium uniformly dark grey (1F2), those with little aerial mycelium having a pinkish brown (8B4) pigment within the agar, the dark bases of the acervuli and the colour of the conidial ooze visible through the agar. Conidia (12–)14.5–16.5(–21.5) × (3.5–)4.5–5(–6) µm (av. 15.5 × 4.8 µm, n = 96), cylindric, straight, sometimes slightly constricted near centre, ends broadly rounded. Appressoria about 6–12 µm diam., globose to short-cylindric, rarely lobed. Perithecia not seen.
Geographic distribution and host range: Known from Carica papaya and Persea americana from Queensland, Australia, and from Coffea berries from Fiji. Simmonds (1965) reported from Australia what he considered to be the same fungus also from Mangifera indica, Malus sylvestris, and “many other hosts”.
Holotype: Australia, Queensland, Ormiston, on Carica papaya, coll. J.H. Simmonds, Oct. 1965, IMI 117612.
Epitype: Australia, Queensland, Brisbane, on Carica papaya, coll. J.H. Simmonds 11663C, Sep. 1965, epitype here designated PDD 28797; ex-epitype culture ICMP 1778.
