Many members of the genus cause economic and environmental impact diseases in nurseries, horticulture, forest, and natural ecosystems and many are of regulatory concern around the world. At present, there are 223 described species, including eight unculturable and three lost species. Twenty-eight species need to be redescribed or validated. A lectotype, epitype or neotype was selected for 20 species, and a redescription based on the morphological/molecular characters and phylogenetic placement is provided. In addition, the names of five species are validated: , (Synonym: ), , and for which morphology and phylogeny are given. Two species, and are presented as new combinations. is treated with a representative strain as both lecto- and epitypification are pending. This manuscript provides the updated multigene phylogeny and molecular toolbox with seven genes (ITS rDNA, , , , , , and ) generated from the type specimens of 212 validly published, and culturable species (including nine hybrid taxa). The genome information of 23 types published to date is also included. Several aspects of the taxonomic revision and phylogenetic re-evaluation of the genus including species concepts, concept and position of the phylogenetic clades recognized within are discussed. Some of the contents of this manuscript, including factsheets for the 212 species, are associated with the ": molecular and morphological identification of based on the types" online resource (https://idtools.org/tools/1056/index.cfm). The first version of the online resource released to the public in September 2019 contained 161 species. In conjunction with this publication, we are updating the online resource to version 2 to include the 51 species recently described. The current status of the 223 described species is provided along with information on type specimens with details of the host (substrate), location, year of collection and publications. Additional information is provided regarding the ex-type culture(s) for the 212 valid culturable species and the diagnostic molecular toolbox with seven genes that includes the two metabarcoding genes (ITS and ) that are important for Sanger sequencing and also very valuable Molecular Operational Taxonomic Units (MOTU) for second and third generation metabarcoding High-throughput sequencing (HTS) technologies. The online resource will continue to be updated annually to include new descriptions. This manuscript in conjunction with represents a monographic study and the most updated revision of the taxonomy and phylogeny of widely considered one of the most important genera of plant pathogens.
