Marthamyces manglicola, a new species (Ascomycota, Marthamycetaceae) on black mangrove from Cozumel Island, Mexico
Background and Aims: The genus Marthamyces is characterized by its orbicular to polygonal apothecia, immersed within the host tissue, erumpent from the substrate surface, by the hymenium with pruinose appearance due to the presence of small crystals on its surface and amongst the paraphyses, and by...

| description | Background and Aims: The genus Marthamyces is characterized by its orbicular to polygonal apothecia, immersed within the host tissue, erumpent from the substrate surface, by the hymenium with pruinose appearance due to the presence of small crystals on its surface and amongst the paraphyses, and by filiform, 0- to 3-septate ascospores. 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. |

Antecedentes y Objetivos: El género Marthamyces se caracteriza por sus apotecios orbiculares a poligonales inmersos en el tejido del hospedero y errumpentes en la superficie del sustrato, por el himenio con apariencia pruinosa debido a la presencia de cristales sobre su superficie himenial y entre las paráfisis, y por las ascosporas filiformes, con 0 a 3 septos. Miembros de este género crecen sobre hojas de plantas en todo el mundo, principalmente en los trópicos y subtrópicos. Los objetivos de este estudio son describir e ilustrar a Marthamyces manglicola como especie nueva que crece sobre Avicennia germinans (mangle negro) de la Isla de Cozumel y elaborar una clave de todas las especies del género Marthamyces descritas hasta el momento.Métodos: Los especímenes fueron recolectados en hojas caídas de mangle negro en el Parque Ecológico Punta Sur de la Reserva de la Biosfera Isla Cozumel. Los datos de campo y las características morfológicas fueron registrados usando las técnicas tradicionales en micología. El material fue depositado en el herbario ENCB de la Escuela Nacional de Ciencias Biológicas del Instituto Politécnico Nacional.Resultados clave: Marthamyces manglicola se caracteriza por sus apotecios que abren en 3-5 solapas pruinosas, variando en coloración de blanco-amarillentos a amarillo pálidos, una superficie himenial azul-grisácea a azul opaca en especímenes jóvenes, decolorando de blanco-azulado a azul pálido o amarillo pálido en apotecios maduros. Microscópicamente, este tiene paráfisis ligeramente ensanchadas cerca del ápice, con varias proyecciones cortas semejantes a dedos y ascosporas rectas a ligeramente curvadas. Se presenta una clave para todas las especies descritas de Marthamyces.Conclusiones: Marthamyces manglicola crece sobre Avicennia germinans (mangle negro) y es la única especie de este género descrita de manglares.
