Abstract:A morphologically distinct isolate of Cladosporium sphaerospermum from a North American patent collection, referenced as Cladosporium lignicola in the patent, was examined. Generic affinity was confirmed by scanning electron microscopic examination of conidiogenous loci and conidial hila. Species identity as C. sphaerospermum was indicated by DNA sequence data derived from actin and translation elongation factor 1-α genes, and the internal transcribed spacer region. The isolate broadens the morphological limits of C. sphaerospermum by production of obclavate, occasionally transversely septate conidia with subrostrate conidiogenous apices ('alternarioid' conidia), and by production of conidia larger than those in prior standard descriptions. Type material of C. lignicola was re-examined and compared with the North American fungus, from which it is morphologically distinct. The decision to reduce C. lignicola to synonymy under C. herbarum was confirmed.

- 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, topical and book 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. For effective publication under the International Code of Botanical Nomenclature the online published papers will be distributed in printed form to several libraries at the same time.
Hard copy volumes: Twice a year (June and December) the online published papers will be bound. These volumes new style will be in A4 format and full colour and will be available through the Publications Department of the National Herbarium of the Netherlands.
Persoonia is a journal published jointly by the Nationaal Herbarium Nederland and the Centraalbureau voor Schimmelcultures.
