Type species – Rehmiodothis osbeckiae (Berk. & Broome) Theiss. & Syd.

Notes – Rehmiodothis species are typical tar spot pathogens which have flattened dome-shaped, glossy, black stromata, with ascomatal ostioles emerging through the leaf surface as slightly protruding structures (Swart 1987). The stromata originate in or beneath the epidermis, become heavily melanised and contain a few ascomata with oblique necks. The haustoria originate from vegetative hyphae growing between palisade cells (Park et al. 2000). Rehmiodothis osbeckiae causes black, shiny and tar-spots in living leaves of Melastoma malabathricum, with oblong to egg-shaped, light-coloured, unequally 2-celled and ascospores that are constricted at septa (Narendra & Rao 1976).
