GARZA OCANAS, Fortunato et al. Macrofungi species from thornscrubsin Northeast Mexico. Rev. mex. de cienc. forestales [online]. 2023, vol.14, n.79, pp.213-236.  Epub 06-Out-2023. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v14i79.1365.

Thornscrubs cover large areas in Northeast Mexico and few species of macrofungi have been reported. The objective of this study was to know the diversity of macrofungi associated with thornscrubs. The results showed a diversity of 218 fungal taxa, belonging to 145 genera and 62 families. 186 species are distributed in both states of Nuevo León and Tamaulipas, 23 only in Tamaulipas and nine only in Nuevo León. 34 of these species are new records for Northeast Mexico. Basidiomycetes are the most diverse with 187 species, 125 genera and 50 families, followed by Ascomycetes with 23 species, 13 genera and seven families. The Myxomycetes (formerly considered as fungi) were less abundant with eight species, seven genera and five families. As for the genera with the greatest richness, Xylaria had fourteen taxa it was followed by Amanita ten, Lactarius and Lentinus six, Ganoderma, Phellinus and Geastrum four, Boletus three, and the rest less than three. Regarding the edibility of the taxa, 175 were not edible, 18 edible and 25 toxic species were recorded. In relation to growth habit, 62 are mycorrhizal, 117 are saprotrophic, 31 are parasitic and eight are phagotrophic. The altitudinal distribution showed that 94 taxa were recorded between 100 and 500 m of altitude and 104 species grow between 500-700 m. Mycorrhizal and parasitic fungi are associated with 41 plant species.
