New records of Boletales (Basidiomycota) in a tropical oak forest from Mexican Southeast

Abstract

Background: Derived from the study of mycobiota associated with Quercus oleoides, tropical holm oak forests in Tabasco have been explored, finding a great diversity in numerous fungal groups, such as boletoid macromycetes. Question: What is the diversity of Boletales mycobiota associated with tropical holm oaks of Tabasco? Species Study: Boletales, Quercus oleoides Study sites and date: municipality of Balancán in the state of Tabasco, Mexico. 2012 - 2016. Methods: Boletoid fungi associated with Q. oleoides were collected according to conventional mycological techniques. A dichotomous key of the species found was made and data on their geographical distribution are included. Results: Nine species assigned to five genera and two families were identified. Conclusions: Boletellus ananas, Boletus auripes, Boletus vermiculosus, Butyriboletus floridanus, Phylloporus centroamericanus, Porphyrellus indecisus, Tylopilus alboater, Gyroporus ballouii and Gyroporus castaneus are new records for the state of Tabasco, Mexico. The distribution of these species is wider than what has been reported in the literature. This work constitutes the first study of macromycetes associated with tropical holm oaks in southeastern México.
