Reassessing Vermisporium (Amphisphaeriaceae), a genus of foliar pathogens of eucalypts
The genus Vermisporium presently accommodates 13 species, 11 of which are associated with leaf spots of eucalypts in the Southern Hemisphere. Vermisporium is chiefly distinguished from Seimatosporium (Amphisphaeriaceae) on the basis of a short exogenous basal
appendage, and the absence of a recognisable apical appendage. Due to the increasing importance of these species in native forests, and confusion pertaining to their taxonomy, a revision of the genus was undertaken based on fresh collections and dried herbarium specimens. Results from DNA
sequence data analyses of the nrDNA-ITS and 28S nrRNA genes for species of Vermisporium indicated the genus to be a synonym of Seimatosporium. New combinations are introduced in Seimatosporium for several species: S. acutum, S. biseptatum, S. brevicentrum,
S. obtusum, S. orbiculare, S. verrucisporum and S. walkeri. An updated key to all species occurring on eucalypts is also provided.

- Persoonia aims to publish papers dealing with molecular phylogeny and evolution of fungi. A further aim is to promote fungal taxonomy by employing a polythetic approach to clarify the true phylogeny and relationships within the kingdom Fungi. The journal publishes high-quality papers elucidating known and novel fungal taxa at the DNA level, and also strives to present novel insights into evolutionary processes and relationships. Papers to be considered include research articles and reviews.
Papers are published using a Fast Track system. This implies that the papers are immediately published online and freely available through the internet via this website. Volumes appear twice a year (June and December). From Volume 36 onwards (2016) hard copy volumes will only be made available through printing-on-demand. The issues can be ordered separately through the Publication Division of Naturalis Biodiversity Center; e-mail: [email protected].
Persoonia is a journal published jointly by the Naturalis Biodiversity Center and the Westerdijk Fungal Biodiversity Institute. - Editorial Board
