Seiridium (Sporocadaceae): an important genus of plant pathogenic fungi.
The genus Seiridium includes multiple plant pathogenic fungi well-known as causal organisms of cankers on Cupressaceae. Taxonomically, the status of several species has been a topic of debate, as the phylogeny of the genus remains unresolved and authentic ex-type cultures are mostly absent. In the present study, a large collection of Seiridium cultures and specimens from the CBS and IMI collections was investigated morphologically and phylogenetically to resolve the taxonomy of the genus. These investigations included the type material of the most important Cupressaceae pathogens, Seiridium cardinale, S. cupressi and S. unicorne. We constructed a phylogeny of Seiridium based on four loci, namely the ITS rDNA region, and partial translation elongation factor 1-alpha (TEF), β-tubulin (TUB) and RNA polymerase II core subunit (RPB2). Based on these results we were able to confirm that S. unicorne and S. cupressi represent different species. In addition, five new Seiridium species were described, S. cupressi was lectotypified and epitypes were selected for S. cupressi and S. eucalypti.
期刊介绍:
Persoonia aspires to publish papers focusing on the molecular systematics and evolution of fungi. Additionally, it seeks to advance fungal taxonomy by employing a polythetic approach to elucidate the genuine phylogeny and relationships within the kingdom Fungi. The journal is dedicated to disseminating high-quality papers that unravel both known and novel fungal taxa at the DNA level. Moreover, it endeavors to provide fresh insights into evolutionary processes and relationships. The scope of papers considered encompasses research articles, along with topical and book reviews.
