Mariannaea is a genus of fungi belonging to the family Nectriaceae.[1]

The genus has cosmopolitan distribution.[1]

The fungal genus was formally established by Samson (1974) to accommodate M. camptospora, M. elegans and the variety M. elegans var. punicea and was typified by M. elegans.[2] The genus is characterized by branched, septate conidiophores with hyaline, flask-shaped phialides, 1–2-celled hyaline conidia mostly forming imbricate chains or slimy heads (Samson 1974;[2] Samson and Bigg 1988;[3] Samuels and Seifert 1991).[4] The sexual morph of Mariannaea has been linked to genus Nectria (Samuels and Seifert 1991),[4] and genus Cosmospora (Gräfenhan et al. 2011).[5] However, Cosmospora and Nectria have been shown polyphyletic within the Nectriaceae family, while genus Mariannaea formed a monophyletic clade within Nectriaceae. Therefore, Gräfenhan et al. (2011) retained Mariannaea as a distinct genus in Nectriaceae.[5] Five new species were further introduced in the genus (Crous et al. 2019;[6] Hyde et al. 2020b;[7] Boonmee et al. 2021;[8] Watanabe and Hirose 2021;[9] Yang et al. 2021).[10] /
