The use of molecular tools for the systematic study of fungi is enabling the boundaries of some species for which a wide ecology and geographical distribution was assumed to be reassessed. The present work aims to establish the taxonomic identity of some recently sequenced Spanish samples belonging to the genus Fomes by means of a phylogeny built w...

Third study of the fungi that grow in the zones of dunes of the Iberian Peninsula and the Balearic Islands

Mycena sect. Calodontes is a taxonomically intricate group comprising phylospecies so far not recognizable using a morphological recognition approach. In this study we re-examine and sequence Iberian material of Porpoloma aranzadii, including the type specimen. The dextrinoid lamellar trama and mycelial hyphae in the type specimen, the latter cover...

Two species of Psathyrella from Girona (Catalonia, Spain), P. phegophila and P. pseudogordonii, are fully described, including data on their ecology, chorology and taxonomy, and illustrated by colour pictures and micrographs.

Clitopilus fuscoumbonatus is described and illustrated as a new species belonging to the subgenus Rhodophana on the basis of a collection from Spain. The new species is characterised by darkly coloured basidiomata, with a sharply umbonate pileus, small, widely ellipsoid, undulate-verruculose basidiospores and by clamped hyphae.

Russula flavispora Romagn., a rare species found in Catalonia. Russula flavispora Romagn., is a rare and interesting species of the genus. This is the first report in Catalonia and, probably, also in the Iberian Peninsula. A description and iconography based on three collections is given.

The authors describe and comment several collections of Tubaria decurrens (Peck) Murrill, a species originally described from Kansas (North America) and found in Catalonia (Spain, Iberian peninsula). A synonymy is proposed with Omphalia subfulviceps Murrill and Tubaria omphaliopsis Singer (= Melanomphalia omphaliopsis (Singer) Singer). Microscopic...
