First record of Macrovalsaria megalospora (Dothideomycetes-Ascomycota) from Colombia

Background and Aims: Macrovalsaria is a monotypic genus of Dothideomycetes, widely cited from tropical and dry regions in Africa, Asia and Australia. In America it has only been described from French Guiana and Mexico; therefore, this study aims to describe Macrovalsaria megalospora for the first ti...

description Background and Aims: Macrovalsaria is a monotypic genus of Dothideomycetes, widely cited from tropical and dry regions in Africa, Asia and Australia. In America it has only been described from French Guiana and Mexico; therefore, this study aims to describe Macrovalsaria megalospora for the first time from Colombia. Methods: The specimens were collected in the Caribbean region of Colombia; simultaneously, the hosts on which they grew were registered, and they were described and identified according to the traditional techniques in mycology. In addition, the spores were observed with the scanning electron microscope. The material is deposited in the fungus collection of the ENCB and HEUS herbaria, of the Escuela Nacional de Ciencias Biológicas of the Instituto Politécnico Nacional in Mexico and of the Universidad de Sucre in Colombia, respectively. Key results: The description of Macrovalsaria megalospora from Colombia is presented, a species that is characterized by the formation of erumpent pseudothecia, gregarious on dead trees of Ficus americana and Terminalia amazonia. Conclusions: This species is widely distributed in various zones of the Paleotropical region and recently it has been discovered in the Neotropics. However, it is necessary to conduct a phylogenetic revision of the specimens identified as Macrovalsaria megalospora of all tropical regions of the world and confirm that it is a monotypic genus, as well as its importance as a phytopathogen.

Antecedentes y Objetivos: Macrovalsaria es un género monotípico de Dothideomycetes, ampliamente citado de regiones tropicales y secas en África, Asia y Australia. En América solo se ha descrito de Guayana Francesa y México, por lo que en el presente estudio se tiene por objetivo reportar a Macrovalsaria megalospora por primera vez para Colombia. Métodos: Los ejemplares se recolectaron en la región Caribe de Colombia; al mismo tiempo se registraron los hospederos en los cuales crecían, se describieron y determinaron de acuerdo con las técnicas tradicionales en micología. Adicionalmente, las esporas se observaron en el microscopio electrónico de barrido. El material está depositado en los herbarios ENCB y HEUS, de la Escuela Nacional de Ciencias Biológicas del Instituto Politécnico Nacional en México y de la Universidad de Sucre, Colombia, respectivamente. Resultados clave: Se presenta la descripción de Macrovalsaria megalospora de Colombia, una especie que se caracteriza por formar pseudotecios errumpentes, gregarios en árboles recíen muertos de Ficus americana y Terminalia amazonia. Conclusiones: Esta especie se distribuye ampliamente en diversas zonas de la región Paleotropical y recientemente se ha descubierto en la Neotropical; no obstante, es necesario realizar una revisión filogenética de los especímenes determinados como Macrovalsaria megalospora de todas las áreas tropicales del mundo, y corroborar tanto que se trata de un género monotípico, como la importancia que tiene como fitopatógena.
