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.

TL;DR: It is indicated that there may have been at least four independent losses of the flagellum in the kingdom Fungi, and the enigmatic microsporidia seem to be derived from an endoparasitic chytrid ancestor similar to Rozella allomycis, on the earliest diverging branch of the fungal phylogenetic tree.

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.
