Previous studies of micro-fungi on Pandanaceae have not included phylogenetic support. Inspiration for this study came from the book Fungi Associated with Pandanaceae by Whitton, McKenzie and Hyde in 2012. Both studies reveal that the micro-fungi on Pandanaceae is particularly rich in hyphomycetes. All data presented herein are based on morphological examination of specimens, coupled with phylogenetic sequence data to better integrate taxa into appropriate taxonomic ranks and infer their evolutionary relationships.

This is a continuity of a series of taxonomic and phylogenetic papers on the fungi where materials were collected from many countries, examined and described. In addition to extensive morphological descriptions and appropriate asexual and sexual connections, DNA sequence data are also analysed from concatenated datasets to infer phylogenetic relationships and substantiate systematic positions of taxa within appropriate ranks. Wherever new species or combinations are proposed, we apply an integrative approach using morphological and molecular data as well as ecological features wherever applicable. Notes on 112 fungal taxa are compiled in this paper including Biatriosporaceae and Roussoellaceae, Didysimulans gen. nov., 81 new species, 18 new host records and new country records, five reference specimens, two new combinations, and three sexual and asexual morph reports.

The authors established the taxonomic status of endophytic fungi associated with leaves of Pandanaceae collected from southern Thailand. Morphotypes were initially identified based on their characteristics in culture and species level identification was done based on both morphological characteristics and phylogenetic analyses of DNA sequence data. Twenty-two isolates from healthy leaves were categorised into eight morphotypes. Appropriate universal primers were used to amplify specific gene regions and phylogenetic analyses were performed to identify these endophytes and established relationships with extant fungi. The authors identified both ascomycete and basidiomycete species, including one new genus, seven new species and nine known species. Morphological descriptions, colour plates and phylogenies are given for each taxon.
