Halegrapha intergrapha is a species of bark-dwelling script lichen in the family Graphidaceae.[1] It forms a thin, whitish-grey crust on tree bark and produces black, branching, slit-like fruiting bodies. The species is known from lowland rainforests in Malaysia, including sites in Peninsular Malaysia and Borneo.
Halegrapha intergrapha was formally described in 2011 by Robert Lücking, based on material collected in Malaysia by the American lichenologist Mason Hale in 1965. In the same work, the authors introduced the genus Halegrapha (family Graphidaceae), and they noted that Hale had recognized this distinctive group but did not have time to publish it himself.[2]
The specific epithet intergrapha refers to the lichen's "in-between" appearance: it combines the outward look of typical Graphis (black, strongly carbonized lirellae on a pale, crystal-rich thallus) with internal features more typical of Phaeographis and relatives, such as a Phaeographis-type hymenium and brown, septate spores. Hale initially intended to describe the species in Phaeographis because of its spore type, and the later authors retained his unpublished epithet when they formally described it.[2]
