Macrohilum H.J. Swart, Trans. Brit. Mycol. Soc. 90: 288 (1988)

Index Fungorum number: IF11123; 1 species with sequence data.

Conidiomata immersed, becoming erumpent, medium brown, globose. Conidiogenous cells lining the inner cavity, pale brown, cylindrical, proliferating percurrently near the apex. Conidia solitary, medium to dark brown, ovoid, smooth, guttulate, developing a single supra-median septum, thick-walled, frequently constricted at the septum, apex obtuse, base truncate with a visible scar.

Type species – Macrohilum eucalypti H.J. Swart

Notes – The monotypic genus Macrohilum was introduced by Swart (1988a) with M. eucalypti, the type species. Macrohilum resembles coniothyrium-like taxa but is phylogenetically distinct as it has a protruding hilum (Crous et al. 2015a, Wijayawardene et al. 2016b). Furthermore, the four base pairs differences observed in their ITS sequences suggest that New Zealand isolates may probably represent a novel Macrohilum species.
