Description:
Recent studies on the fungal families Lophiostomataceae and Lophiotremataceae (Pleosporales) have
provided varying phylogenetic and taxonomic results concerning constituent genera and species. By adding DNA
sequences of 24 new strains of Lophiostomataceae and nine new strains of Lophiotremataceae to a sequence
data matrix from international databases, we provide a new understanding of the relationships within these families.
Multigene analysis of the four molecular markers ITS, LSU, TEF1-α, and RPB2 reveals that the genera within Lophiotremataceae are phylogenetically well supported. Lophiostoma myriocarpum is recognised as a species of Lophiotrema in contrast to earlier concepts. In Lophiostomataceae, we resurrect a broad generic concept of the genus
Lophiostoma and reduce 14 genera to synonymy: Alpestrisphaeria, Biappendiculispora, Capulatispora, Coelodictyosporium, Guttulispora, Lophiohelichrysum, Lophiopoacea, Neopaucispora, Neotrematosphaeria, Platystomum,
Pseudocapulatispora, Pseudolophiostoma, Pseudoplatystomum, and Sigarispora. Nine new species are described
based on molecular data and in most cases supported by morphological characters: Antealophiotrema populicola,
Atrocalyx nordicus, Lophiostoma carpini, Lophiostoma dictyosporium, Lophiostoma erumpens, Lophiostoma fusisporum, Lophiostoma jotunheimenense, Lophiostoma plantaginis, and Lophiostoma submuriforme. Lophiostoma
caespitosum and Lophiotrema myriocarpum are lecto- and epitypified to stabilise their species concepts. High
intraspecific variability of several morphological traits is common within Lophiostomataceae.
