Meliola. 
Fungi living on the surface of leaves, more seldom on branches. Peri- 
thecigerous mycelium dark brown, thick, always provided with capitate 
hyphopodia (small 2-celled processes, which G-aillard calls abortive peri- 
thecia), and very often with mucronate hyphopodia (abortive mycelial 
branches), and frequently with setae (sterile, erect branches). Perithecia 
globose or ovoid, rarely dimidiate, carbonaceous, astomous, or with a false 
ostiole formed of more delicate, paler cells. Asci spherical or ovoid, rarely 
cylindrical or claviform, usually evanescent. Spores brown at maturity, 
large, transversely 2-5 septate. Conidiiferous mycelium slender, paler. 
Conidia fusiform, transversely septate.
