CAPPELLO-GARCIA, Silvia et al. New records of the genus Ganoderma (Agaricomycetes, Polyporales) for Mexico and Tabasco. Rev. Mex. Biodiv. [online]. 2023, vol.94, e945013.  Epub 14-Jun-2024. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2023.94.5013.

The genus Ganoderma has been poorly studied in southeastern Mexico. The aim of this study was to contribute to the knowledge of diversity of species of the Ganoderma for Mexico and Tabasco. Two hundred and forty seven herbarium specimens from 16 municipalities of the state were analyzed. The macro and micromorphological characteristics of the basidiomes were observed. Microscopic observations were made in KOH at 5%, and taxonomic determination was made using various specialized keys. Twenty-one species of Ganoderma were identified and described, of which 17 correspond to the subgenus Ganoderma and 4 to the subgenus Elfvingia. G. carnosum, G. dunense, G. lipsiense, G. multipileum, G. multiplicatum, G. neojaponicum, G. orbiforme, G. philippii, G. sichuanense, G. stipitatum, and G. subresinosum are new records for Mexico. These species are also new reports for Tabasco, including G. australe, G. oerstedii, G. oregonense, G. sessiliforme, G. tsugae, and G. zonatum. A dichotomous key is presented for the identified species. The inventory reflects the diversity of Ganoderma in Mexico and the Tabasco tropics.
