The class Geoglossomycetes is a recently created class of Ascomycota, currently comprised of one family (Geoglossaceae) and five genera (Geoglossum, Nothomitra, Sarcoleotia, Thuemenidium and Trichoglossum). These fungi, commonly known as earth tongues, have long been a subject of mycological research. However, the taxonomy within the group has historically been hindered by the lack of reliable morphological characters, uncertain ecological associations, and the inability to grow these fungi in culture. The phylogenetic relationships of Geoglossomycetes were investigated by conducting maximum likelihood and Bayesian analyses using a 4-gene dataset (ITS, LSU, MCM7, RPB1). Five well-supported monophyletic clades were found that did not correspond exactly with the currently recognised genera, necessitating a taxonomic revision of the group. Two new genera are proposed: Glutinoglossum to accommodate G. glutinosum and the newly described species G. heptaseptatum, and Sabuloglossum to accommodate S. arenarium. The type species of Thuemenidium, traditionally included within the Geoglossaceae, is confirmed as belonging to a separate lineage that is only distantly related to Geoglossomycetes.

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.
