Type speciesNeomelanconiella combreti Crous

Notes – The monotypic genus Neomelanconiella was introduced by Crous et al. (2018b) based on N. combreti. The sexual morph is undetermined and the asexual morph is similar to Melanconiella (Crous et al. 2018b). However, most of Melanconiella species occur on recently dead twigs and branches of Betulaceae in the north temperate zone (Voglmayr et al. 2012), while Neomelanconiella combreti occurs on leaves of Combretaceae in the Southern Hemisphere. Neomelanconiella differs from Melanconiella in having pycnidial conidiomata without ectostromatic discs and central columns and ellipsoid conidia without two large and numerous small guttules. Phylogenetically Neomelanconiella combreti clustered with Cryptodiaporthe vepris forming a distinct clade between Melanconiellaceae and Harknessiaceae (Crous et al. 2018b).
