| Junghuhnia is a genus of polypores traditionally characterised by a dimitic hyphal system with clamped generative hyphae and presence of encrusted skeletocystidia. However, recent molecular studies revealed that Junghuhnia is polyphyletic and most of the species cluster with Steccherinum, a morphologically similar genus separated only by a hydnoid hymenophore. In the Neotropics, very little is known about the evolutionary relationships of Junghuhnia s.lat. taxa and very few species have been included in molecular studies. In order to test the proper phylogenetic placement of Neotropical species of this group, morphological and molecular analyses were carried out. Specimens were collected in Brazil and used for DNA sequence analyses of the internal... |

| The systematic integrity of European Gymnopus subsect. Levipedes is verified based on anatomicmorphological characters with support from DNA sequences of ITS and translation elongation factor 1-alpha genes. Seven species (G. alpinus, G. aquosus, G. dryophilus – including var. lanipes, G. erythropus, G. fagiphilus, G. hybridus, and G. ocior) belonging to this subsection are included. We clarify the concepts of G. dryophilus and G. ocior, which were occasionally confused in older literature. Due to unavailability of previously selected neotype of G. dryophilus the substitute neotype specimen is selected. Gymnopus dryophilus var. lanipes is confirmed as a variety; no important differences from nominotypical variability were detected. All discriminative... |

| Clavaria species with dark basidiomata occurring in Europe were analysed using morphological and molecular methods. Morphological analyses revealed four groups containing seven Clavaria species with dark basidiomata. Phylogenetic analysis of the LSU nrDNA region confirmed the separate positions of all seven Clavaria species within the genus. All sequences were grouped in four well-supported clades, mostly corresponding to defined morphological species. The results of the molecular study are inconsistent with the infrageneric classification of Clavaria based on the presence or absence of clamps on the bases of basidia and two widely accepted subgenera. Clavaria and Holocoryne appear to be polyphyletic. A new approach in species delimitation is presented: 1)... |
