TL;DR: Among the regions of the ribosomal cistron, the internal transcribed spacer (ITS) region has the highest probability of successful identification for the broadest range of fungi, with the most clearly defined barcode gap between inter- and intraspecific variation.
Journal ArticleDOI
The Colletotrichum gloeosporioides species complex
TL;DR: The limit of the Colletotrichum gloeosporioides species complex is defined genetically, based on a strongly supported clade within the Col letteredum ITS gene tree, as well as all taxa accepted within this clade, as it has been applied in the literature for the past 50 years.
Journal ArticleDOI
Colletotrichum - current status and future directions.
TL;DR: A review is provided of the current state of understanding of Colletotrichum systematics, focusing on species-level data and the major clades, and the taxonomic placement of the genus is discussed.
Journal ArticleDOI

TL;DR: A 6-gene, 420-species maximum-likelihood phylogeny of Ascomycota, the largest phylum of Fungi, and a phylogenetic informativeness analysis of all 6 genes and a series of ancestral character state reconstructions support a terrestrial, saprobic ecology as ancestral are presented.

TL;DR: A set of standards and protocols are proposed to improve the data quality of new sequences, and it is suggested how type and other reference sequences can be used to improve identification of Fungi.
