Ionomidotis mesophila (Ascomycota, Cordieritidaceae), a new species from tropical cloud forest in Mexico
Background and Aims: The ascomycete genus Ionomidotis is characterized by solitary to caespitose ascomata, discoid to spathulate, olive to black, that release purple, violet, olive or green pigments in KOH. It is found in the order Helotiales of the class Leotimycetes. The present study aims to desc...

| description | Background and Aims: The ascomycete genus Ionomidotis is characterized by solitary to caespitose ascomata, discoid to spathulate, olive to black, that release purple, violet, olive or green pigments in KOH. It is found in the order Helotiales of the class Leotimycetes. The present study aims to describe Ionomidotis mesophila as a new species for science.Methods: The specimens were collected in 2017 and 2019 in the municipality of Honey, Puebla, Mexico. The samples were studied and determined according to traditional techniques in mycology and were deposited in the fungus collection of the herbarium of the Escuela Nacional de Ciencias Biológicas of the Instituto Politécnico Nacional.Key results: The genus Ionomidotis is registered for the first time from Mexico and I. mesophila is decribed as a new species characterized by spathulate to cupuliform apothecia with a wavy, grayish brown margin that, in the presence of 5% KOH, releases fresh green to olive-brown pigments; paraphyses with rounded to globose apices and ellipsoid ascospores. It grows on recently fallen Quercus in cloud forest.Conclusions: Ionomidotis mesophila is a new species for cloud forest inventories in Mexico. It is necessary to accelerate efforts to inventory and describe the fungal diversity of tropical cloud forest, actually defined as an ecosystem in danger of extintion in the country.

Antecedentes y Objetivos: Ionomidotis es un género de Ascomicetos que se caracteriza por ascomas solitarios a cespitosos, discoides a espatulados de colores oliváceos a negros, que liberan pigmentos de color púrpura, violeta, oliváceos o verdes en KOH; se encuentra en el orden Helotiales de la clase Leotimycetes. El presente estudio tiene como objetivo describir a Ionomidotis mesophila por primera vez para la ciencia.Métodos: Los especímenes fueron recolectados en 2017 y 2019 en el municipio Honey, Puebla, México. Los ejemplares fueron estudiados de acuerdo con las técnicas tradicionales en micología y depositados en la colección de hongos del herbario de la Escuela Nacional de Ciencias Biológicas del Instituto Politécnico Nacional. Resultados clave: Se registra por primera vez para México al género Ionomidotis y se describe a I. mesophila como especie nueva que se caracteriza por formar apotecios espatulados a cupuliformes, con margen ondulado, de color marrón grisáceo, que en presencia de KOH al 5% libera pigmentos de color verde en fresco a marrón oliváceos; paráfisis con ápices redondeados a globosos y ascoporas elipsoides. Crece sobre troncos recién caídos de Quercus en bosque mesófilo de montaña. Conclusiones: Ionomidotis mesophila es una especie nueva para los inventarios del bosque de niebla en México, lo que nos lleva a acelerar esfuerzos por describir la diversidad fúngica del bosque mesófilo de montaña, actualmente definido como un ecosistema en peligro de extinción en el país.
