Abstract

Meristematic fungi are mainly defined as having aggregates of thick-walled, melanised cells enlarging and reproducing by isodiametric division. black meristematic and meristematic-like fungi have been allied to , which currently has two accepted families, and , with fungi mainly regarded as pathogens, parasites, saprobes and epiphytes of different plant species. This study aimed to verify the phylogenetic position using four nuclear markers (SSU, LSU, ITS and ) of the genera associated with , namely , , and , and the new genus, . (including . and .), established for endophytic fungi occurring in cacti in Brazil. Based on morphology, lifestyle and phylogenetic inferences, these black meristematic and meristematic-like fungi cannot be accommodated in . Combining these results, three new orders and two new families are introduced: . (including . for .), . (including for ) and . (including . for ). and remained due to their disposition in the phylogenetic tree, that moved among clades accordingly with the gene analysed. Our results show that the inclusion of endophytic fungi obtained from plants in dry forests can contribute to the discovery of new taxa, clarify the phylogenetic position of allied taxa and confer information to the estimation of national and global fungal diversity.
