| Shrnutí: | 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.
