This paper provides illustrated descriptions of micro-fungi newly found on Pandanaceae in China and Thailand. The fungi are accommodated in 31 families. New taxa described include a new family, seven new genera, 65 new species, 16 previously known species. A new family: Malaysiascaceae (Glomerellales). New genera are Acremoniisimulans (Plectosphaerellaceae), Pandanaceomyces, Pseudoachroiostachy (Nectriaceae), Pseudohyaloseta (Niessliaceae), Pseudoornatispora (Stachybotriaceae) and Yunnanomyces (Sympoventuriaceae). New species are Acremoniisimulans thailandensis, Beltrania krabiensis, Beltraniella pandanicola, B. thailandicus, Canalisporium krabiense, C. thailandensis, Clonostachys krabiensis, Curvularia chonburiensis, C. pandanicola, C. thailandicum, C. xishuangbannaensis, Cylindrocladiella xishuangbannaensis, Dictyochaeta pandanicola, Dictyocheirospora nabanheensis, D. pandanicola, D. xishuangbannaensis, Dictyosporium appendiculatum, Di. guttulatum, Di. hongkongensis, Di. krabiense, Di. pandanicola, Distoseptispora thailandica, D. xishuangbannaensis, Helicoma freycinetiae, Hermatomyces biconisporus, Lasiodiplodia chonburiensis, L. pandanicola, Lasionectria krabiense, Menisporopsis pandanicola, Montagnula krabiensis, Musicillium pandanicola, Neofusicoccum pandanicola, Neohelicomyces pandanicola, Neooccultibambusa thailandensis, Neopestalotiopsis chiangmaiensis, N. pandanicola, N. phangngaensis, Pandanaceomyces krabiensis, Paracylindrocarpon nabanheensis, P. pandanicola, P. xishuangbannaensis, Parasarcopodium hongkongensis, Pestalotiopsis krabiensis, P. pandanicola, Polyplosphaeria nabanheensis, P. pandanicola, P. xishuangbannaensis, Pseudoachroiostachys krabiense, Pseudoberkleasmium pandanicola, Pseudochaetosphaeronema pandanicola, Pseudohyaloseta pandanicola, Pseudoornatispora krabiense, Pseudopithomyces pandanicola, Rostriconidium pandanicola, Sirastachys phangngaensis, Stictis pandanicola, Terriera pandanicola, Thozetella pandanicola, Tubeufia freycinetiae, T. parvispora, T. pandanicola, Vermiculariopsiella hongkongensis, Volutella krabiense, V. thailandensis and Yunnanomyces pandanicola. 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.
