Journal ArticleDOI

Nuclear ribosomal internal transcribed spacer (ITS) region as a universal DNA barcode marker for Fungi

Conrad L. Schoch, +160 more
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

Phylogenetic lineages in the Botryosphaeriaceae

TL;DR: DNA sequence data of the 28S rDNA is employed to resolve apparent lineages within the Botryosphaeriaceae and 10 lineages are recognised, including an unresolved clade including species of Camarosporium/Microdiplodia.
Journal ArticleDOI

The Botryosphaeriaceae: genera and species known from culture

TL;DR: It seems likely that all of the older taxa linked to the Botryosphaeriaceae, and for which cultures or DNA sequence data are not available, cannot belinked to the species in this family that are known from culture, and will have to be disregarded for future use unless they are epitypified.
Journal ArticleDOI

The Ascomycota Tree of Life: A Phylum-wide Phylogeny Clarifies the Origin and Evolution of Fundamental Reproductive and Ecological Traits

Conrad L. Schoch, +65 more
- 01 Apr 2009 - 
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.
Journal ArticleDOI

A class-wide phylogenetic assessment of Dothideomycetes

Conrad L. Schoch, +54 more
- 01 Jan 2009 - 
TL;DR: A genomic comparison of 6 dothideomycete genomes with other fungi finds a high level of unique protein associated with the class, supporting its delineation as a separate taxon.
