Abstract

The discovery and study of three new species ofTrimmatothelopsisfrom Southwestern North America,T. californica,T. mexicana, andT. novomexicana, adds not only to the diversity of the genus and family but generated new insights into the occurrence of two ascus types in the genus and the variety of conidiogenous cells and conidia.Trimmatothelopsisnow includes 15 species with a mainly Holarctic distribution (Asia, Europe, North America) and one species in Australia. A key is supplied to the genus. An overview of the genusTrimmatothelopsisis given, including differentiation from other genera of Acarosporaceae. The monotypic genusThelocarpellais considered to be a synonym ofTrimmatothelopsis. The new combinationTrimmatothelopsis wirthiiis proposed. The ascus type is shown to be variable in the genus with species with two types being intermixed with each other in our phylogeny.
