Open Access Towards an understanding of the genus Glutinoglossum with emphasis on the Glutinoglossum glutinosum species complex (Geoglossaceae, Ascomycota)

Glutinoglossum is one of the earth tongue genera with viscid or glutinous ascocarps. Based on morphology and ITS1-5.8S-ITS2, nrLSU and tef1 sequence data, seven new species are described: G. circinatum, G. lumbricale, G. orientale, G. peregrinans, G. proliferatum, G. pseudoglutinosum, and G. triseptatum. The lectotypes for Geoglossum glutinosum var. lubricum and for Geoglossum glabrum var. majus as well as the epitype for Glutinoglossum glutinosum are designated. The comprehensive morphological study of G. heptaseptatum resulted in the discovery of ascospores germinating by conidia inside the asci, which is first noted for Glutinoglossum species. The status of Cibalocoryne is discussed.

More about this publication?
  • 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.
