Members of this genus grow on leaves of plants throughout the world, mainly in the tropics and subtropics. The aims of this study are to describe and illustrate Marthamyces manglicola as a new species that grows on Avicennia germinans (black mangrove) from Cozumel Island and to elaborate a key to all species of the genus Marthamyces described until now.Methods: Specimens were collected on fallen leaves of black mangrove in Punta Sur Ecological Park, Cozumel Island Biosphere Reserve. Field data and morphological characteristics were recorded using the traditional techniques in mycology. The material was deposited in the ENCB herbarium of the Escuela Nacional de Ciencias Biológicas of the Instituto Politécnico Nacional.Key results: Marthamyces manglicola is characterized by its apothecia opening by 3-5 pruinose and yellowish white to pale yellow flaps, a hymenial surface greyish blue to dull blue in young specimens, fading to bluish white to pale blue or pale yellow in mature apothecia. Microscopically, it has paraphyses swelling slightly near the apex, with several short, finger-like projections and straight to slightly curved ascospores on release. A key to all described species of Marthamyces is presented.Conclusions: Marthamyces manglicola on Avicennia germinans (black mangrove) is the only species of this genus described from mangroves. 2022 artículo científico 0187-7151 https://www.redalyc.org/articulo.oa?id=57470745005 https://www.redalyc.org/journal/574/57470745005/ https://www.redalyc.org/journal/574/57470745005/html/ https://www.redalyc.org/journal/574/57470745005/57470745005.epub https://www.redalyc.org/journal/574/57470745005/movil 10.21829/abm129.2022.1903 en http://www.redalyc.org/revista.oa?id=574 Acta Botanica Mexicana application/pdf Instituto de Ecología, A.C.
