Phylogenetic and taxonomic revision of Lopadostoma.

Jaklitsch WM, Fournier J, Rogers JD, Voglmayr H - Persoonia (2014)

Bottom Line: Most species formerly assigned to Lopadostoma do not belong to the genus.Its type and currently only confirmed species Anthostoma decipiens belongs to Diatrypaceae.Anthostoma insidiosum is an older name for Anthostomella (Diatrype) adusta.

ABSTRACT
The genus Lopadostoma (Xylariaceae, Xylariales) is revised. Most species formerly assigned to Lopadostoma do not belong to the genus. Twelve species are herein recognised, of which two are only known from morphology. Ten species, of which six (L. americanum, L. fagi, L. insulare, L. lechatii, L. meridionale and L. quercicola) are newly described, are characterised by both morphology and DNA phylogeny using LSU, ITS and rpb2 sequences. Morphologically, ecologically and phylogenetically Lopadostoma is a well-defined genus comprising exclusively species with pustular pseudostroma development in bark of angiospermous trees. Phaeosperma ailanthi, Phaeosperma dryophilum and Sphaeria linosperma are combined in Lopadostoma. Lopadostoma gastrinum is neotypified and L. turgidum is lecto- and epitypified. Species with asci and ascospores similar to those of Lopadostoma but having perithecia immersed in wood, particularly those of Lopadostoma subg. Anthostomopsis have been determined to be unrelated to the genus. DNA data confirm that Anthostoma is unrelated to Lopadostoma. Its type and currently only confirmed species Anthostoma decipiens belongs to Diatrypaceae. DNA data also show that L. pouzarii and Barrmaelia macrospora are unrelated to Lopadostoma. A commentary is provided for names in Lopadostoma and those names in Anthostoma that may be putative species of Lopadostoma based on their protologues. Anthostoma insidiosum is an older name for Anthostomella (Diatrype) adusta.

MP and ML bootstrap support above 55 % are given at the first and second position, respectively, above or below the branches. Strain/culture designations are given following the taxon names; holo-, neo- or epitype strains/specimens are formatted in bold. Colours refer to the hosts: red Quercus spp., dark blue Fagus sylvatica, orange Corylus avellana, olive Prunus padus, light green Ulmus spp., dark green Acer campestre, turquoise Carpinus betulus and lavender Pistacia lentiscus.
