Malthomyces is typified by M. calamigena and currently comprises two species including M. coimbatoricus (Species Fungorum 2020). Both these species cause tar spots on palms (Hyde & Cannon 1999) and are saprobes found from India and Sri Lanka. The asexual morph of Malthomyces is undetermined (Wijayawardene et al. 2018a).
Type species: Malthomyces calamigena (Berk. & Broome) K.D. Hyde & P.F. Cannon.
Other accepted species: Species Fungorum – search Malthomyces.
