How important are conidial appendages?
The genus Dinemasporium is used as a case study to evaluate the importance of conidial appendages for generic level classification of coelomycetous fungi. Based on morphology and sequence data of the large subunit nuclear ribosomal RNA gene (LSU, 28S) and the internal transcribed
spacers and 5.8S rRNA gene of the nrDNA operon, the genus Dinemasporium is circumscribed, and an epitype designated for D. strigosum, the type of the genus. A further five species are introduced in Dinemasporium, namely D. pseudostrigosum (isolated from Triticum
aestivum, Germany and Stigmaphyllon sagraeanum, Cuba), D. americana (soil, USA), D. polygonum (Polygonum sachalinense, Netherlands), D. pseudoindicum (soil, USA), and D. morbidum (human sputum, Netherlands and hare dung, New Zealand). Brunneodinemasporium,
based on B. brasiliense, is introduced to accommodate Dinemasporium-like species with tightly aggregated brown conidiogenous cells, and pale brown conidia. Dendrophoma (= Amphitiarospora) is reinstated as distinct from Dinemasporium, and an epitype designated
for D. cytisporoides, characterised by its superficial, stipitate to cupulate conidiomata, and small conidia with two polar, tubular, exogenous appendages. The genus Stauronema is reduced to synonymy under Dinemasporium. Pseudolachnea (1-septate conidia) is supported
as distinct from Dinemasporium (aseptate conidia), an dP. fraxini introduced as a novel species. Taxa in this generic complex differ by combination of morphological characters of conidiomata, setae, conidia and appendages. Appendage morphology alone is rejected as informative
at the generic level.
More about this publication?
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. Fast Track articles are available here
If there are no articles shown in this section, all the Fast Track articles are published in the latest issue of Persoonia.
