Background and Aims:

The Colima Volcanic Complex (CVC) is part of the Transversal Mexican Volcanic Belt, located in the southeast of Jalisco and north of Colima. It includes vegetation belts that change through an altitude gradient ranging from 1200 to just over 4000 m, where it is possible to observe tropical forests, temperate forests and semi-arid zones, as well tropical montane cloud forest. With respect to previous studies on fungal diversity in this region, only 140 species registered in the different municipalities that comprise the CVC area were cited. The objective of the present work is to update the knowledge of the mycobiota registered within the study area.

Methods:

Fungal specimens were collected during the months of June to October between 2011 and 2018. Additionally, the fungal colection of the herbarium IBUG was revised. The macro- and micromorphological study was carried out with conventional mycological techniques and the use of specialized bibliography to identify the material.

Key results:

A total of 2082 specimens were determined to species, corresponding to 408 taxa, of which 360 are Basidiomycota and 48 Ascomycota. Two new records are cited for the Mexican mycobiota: Ductifera exidioidea and Psathyrella longistriata, and 11 for the state of Jalisco: Bulgaria inquinans, Crepidotus applanatus, Gymnopilus sapineus, Hohenbuehelia spathulata, Hygrocybe spadicea, Inocybe obsoleta, Lepiota cristata, Pholiota lubrica, Rhizina undulata, Scleroderma aff. pseudostipitatum and Trichoderma alutaceum. For the state of Colima 20 new records are provided, which until now had not been cited.

Conclusions:

It is considered important to increase systematic studies and mycological explorations that allow us to know more about this resource, its possible use and rational management, as well as the analysis of endemic or endangered species and ecological aspects that may show the current distribution and fungal diversity in this region.
