Molecular phylogeny of Ascotricha, including two new marine algae-associated species.
Phylogenetic analyses based on a broad taxonomic sampling of Ascotricha were conducted using the sequences of nuc rDNA region encompassing the internal transcribed spacers 1 and 2, along with the 5.8S rDNA (ITS), partial nuc 18S rDNA (18S) and partial β-tubulin gene (TUB2). Hypoxyloid Xylariaceae and xylarioid Xylariaceae were inferred as two distinct lineages in the Xylariaceae in the combined ITS-TUB2 phylogeny. Within xylarioid Xylariaceae species of Ascotricha form a monophyletic group. Two new marine algae-associated fungi, Ascotricha longipila and A. parvispora, are described on the basis of morphological and molecular characters and the combination, A. sinuosa, is proposed. A synopsis of the morphological characters and a dichotomous key to Ascotricha species are provided.
