| description | Background and Aims: Wood-degrading macromycetes are the most important organisms in the decomposition of lignocellulose. However, taxonomic and ecological studies are scarce in temperate forests in the State of Mexico, Mexico. The main objective of the study was to provide information on the physical and microclimatic variation of the dead wood of Abies religiosa that influence the diversity of the fungal community in a temperate forest in Huixquilucan, State of Mexico.
Methods: During the rainy season, from September to October 2021, we conducted fieldwork in the Abies religiosa forest located in Huixquilucan, State of Mexico. We sampled 100 dead trunks of A. religiosa and measuring the following variables: pH, temperature, volume, density, humidity, and softness of the wood. Similarly, the number of morphospecies of macromycetes and the abundance of sporomes were recorded. The genera and species of the macromycetes were determined and the values of richness and abundance were compared with the characteristics of the wood through a Canonical Correspondence Analysis (CCA).
Key results: Forty six genera and 27 species were determined, 24 of them are new records for the sampling site. When evaluating the possible association between the dead wood characteristics with richness and diversity of macromycetes, we found that the richness and diversity of sporomes are mainly influenced by the hardness, density, and humidity of wood remains.
Conclusions: The diversity of wood-degrading macromycetes of A. religiosa is very high. Particularly in this forest, the density, hardness, and humidity of the wood are the most important variables modulating the richness and diversity of the sporomes. The density of the wood is related to the humidity and there is no clear association with the hardness of the wood. |

Antecedentes y Objetivos: Los organismos más importantes en la descomposición de la lignocelulosa son los macromicetos degradadores de la madera caída. Sin embargo, los estudios taxonómicos y ecológicos sobre estos hongos son escasos en bosques templados del Estado de México, México. El objetivo de este estudio fue proporcionar información sobre la diversidad de la comunidad fúngica de un bosque templado en Huixquilucan, Estado de México y sobre las variables físicas y microclimáticas de la madera muerta de Abies religiosa que influyen en ella. Métodos: En la temporada de lluvias, en septiembre y octubre de 2021, se exploró un bosque de Abies religiosa ubicado en Huixquilucan, Estado de México. Se recolectaron 100 troncos caídos de A. religiosa, a los que se les midieron las siguientes variables: pH, temperatura, volumen, densidad, humedad y dureza. Se registró el número de morfoespecies de macromicetos y abundancia de esporomas. Se determinaron los géneros y especies de los macromicetos y los valores de riqueza y abundancia se emparejaron con las características de la madera para determinar cuáles variables estaban relacionadas mediante un Análisis de Correspondencia Canónica. Resultados clave: Se determinaron 46 géneros y 27 especies; 24 de ellas son nuevos registros para el sitio de muestreo. Al evaluar la posible asociación entre las características de la madera con la riqueza y diversidad de macromicetos, se reporta que la riqueza y diversidad de los esporomas están mayormente influenciadas por la dureza, densidad y humedad de los restos de madera. Conclusiones: La diversidad de macromicetos degradadores en la madera de A. religiosa es muy alta. Particularmente en el bosque estudiado, la densidad, dureza y humedad de la madera son las variables más importantes que influyen en la riqueza y diversidad de los esporomas. La densidad de la madera está asociada con el contenido de humedad y parece no tener relación con la dureza de la madera.
