Notes: Melanographium was introduced by Saccardo (1913) to accommodate the hyphomycetous taxon and is typified by M. spleniosporum. Melanographium taxa are saprobes and commonly found on dead or decaying wood, leaves, stems, culms or petioles, mostly on palms (Ellis 1963; Goh and Hyde 1997; Somrithipol and Jones 2005). The genus is characterized by having superficial colonies, unbranched and erect brown conidiophores, polyblastic conidiogenous cells with sympodial proliferation, and holoblastic, reniform, aseptate, brown to dark brown conidia (Ellis 1963, 1971). Melanographium includes 14 accepted species mostly based on morphology, but only one species, namely Melanographium phoenicis (MFLUCC 18-1481), have sequence data (Hyde et al. 2020b; Index Fungorum 2021).

Type species: Melanographium spleniosporum Sacc., Annls mycol. 11(6): 558 (1913).

Other accepted species: Species Fungorum – search Melanographium.
