New accounts on Hypoxylaceae and Xylariaceae from Brazil

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

This work aims to bring new reports of Hypoxylaceae and Xylariaceae from Brazil. The collections were performed in cocoa plantations in Ilhéus, Bahia, Brazil. Six new occurrences of Hypoxylaceae and two Xylariaceae species are reported to Brazil, Northeast and/or Bahia. A dichotomous key to the species treated is provided.

Key words:
Ascomycota; Cocoa plantations; Hypoxylaceae; Xylariaceae
