Viene presentata una nuova chiave di determinazione della sezione Fragilipedes del genere Mycena (Pers.) Roussel dell'Emisfero del Nord. Sono inclusi i nuovi taxa pubblicati fra il 1988 e 2003 e le specie trasferite da altre sezioni del genere Mycena e dal genere
Hydropus. Sono elencate le 90 entità (87 specie e 3 varietà) menzionate in questa nuova chiave e sono elencate anche le entità escluse dalla sezione. Inoltre, con lo scopo di dare un valido aiuto per la lettura di questa chiave, sono presentate anche sei tavole

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.
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.
