| description | Background and Aims: Mexico stands out as a megadiverse country, because of its wide range of ecosystems and the diversity of plant species present, including numerous endemic species, which harbor a significant reservoir of arbuscular mycorrhizal fungi (AMF); however, a constant search effort is necessary for the identification and registration of AMF species not yet described in the national territory. The present study aimed to contribute to the knowledge of AMF in Mexico, with the record of Glomus nanolumen described from Hawaiian dunes, and in Mexico it was found in tropical deciduous forest.
Methods: AMF spores were isolated from soil samples collected in tropical deciduous forest, in the state of Guanajuato, by water and sucrose centrifugation and mounted on semi-permanent slides. Taxonomic identification was performed based on the morphological characteristics of the spores, the review of the original description of the species, and online portals specialized in AMF.
Key results: The species Glomus nanolumen was recorded for the first time in Mexico, associated with a tropical deciduous forest; the species is characterized by sporocarps of up to 40 ovoid, irregular or ellipsoidal spores; the structure of the spore wall is composed of two hyaline layers, turning pale yellow, the outer layer has a thickness of less than 1 µm, while the inner layer is rigid and can measure up to 10 µm thick, both layers without reaction in Melzer's reagent. Its description and taxonomic comments are presented.
Conclusion: With the record of G. nanolumen, the presence of 48% of Glomus species in the country is documented, among the 55 species described worldwide. With this contribution we have a total of 163 species of AMF in Mexico. |

Antecedentes y Objetivos: México se distingue por ser un país megadiverso, resultado de su amplia gama de ecosistemas y de la diversidad de especies vegetales presentes que incluyen numerosas especies endémicas, que albergan un reservorio significativo de hongos micorrízicos arbusculares (HMA). Sin embargo, es necesario un esfuerzo de búsqueda constante para la identificación y el registro de especies de HMA aún no descritas en el territorio nacional. El presente estudio tuvo como objetivo contribuir al conocimiento de los HMA en México, con el registro de Glomus nanolumen descrita de dunas de Hawái, y en México se encontró en bosque tropical caducifolio. Métodos: De muestras de suelo recolectado en bosque tropical caducifolio, del estado de Guanajuato, se aislaron esporas de HMA a través de una centrifugación de agua y sacarosa, las cuales se montaron en laminillas semipermanentes. La identificación taxonómica se realizó con base en las características morfológicas de las esporas, en la revisión de la descripción original de la especie, y de portales en línea especializados en HMA. Resultados clave: Se registró la especie Glomus nanolumen por primera vez en México, asociada a un bosque tropical caducifolio; la especie se caracteriza por los esporocarpos de hasta 40 esporas ovoides, irregulares o elipsoidales; la estructura de la pared de la espora está compuesta por dos capas hialinas, tornándose amarillas pálidas, la capa externa tiene un grosor de menos de 1 µm, mientras que la capa interna es rígida y puede llegar a medir hasta 10 µm de grosor, ambas capas sin reacción en reactivo de Melzer. Se presenta su descripción, y comentarios taxonómicos. Conclusiones: Con el registro de G. nanolumen se documenta la presencia de 48% de especies de Glomus en el país, de entre las 55 especies descritas a nivel mundial. Con esta aportación se tiene un total de 163 especies de HMA en México.
