A new species of Barssia (Helvellaceae) is described from Greece based on morphological and
genetic studies. Macroscopic images of fresh specimens, as well as observations made under optical microscopes,
drawings and a 28S nLSU phylogenetic tree are provided. The present work is also accompanied by
a brief discussion and a key to the known species...
A new species of the genus Barssia was identified from Turkey using both morphological and phylogenetic analysis of the ribosomal internal transcribed spacer region (ITS rDNA) and nuclear ribosomal large subunit (LSU rDNA) gene sequences. Macroscopic and microscopic features of the fresh samples were photographed and a diagnostic key of the genus B...

Helvella is a species-rich genus, forming a large variation of astounding ascocarps in many different habitats.
During the last decade, molecular markers and morphological characters have been combined to delimit and identify
cryptic species in this genus. We report on a list of 54 species of Helvella s.s. in the Nordic region and describe five
new species, i.e. H. bresadolae, H. convexa, H. japonica, H. nordlandica and H. oroarctica. The morphological and
molecular characteristics of the new species and the emended / hypocrateriformis, / fibrosa-macropus, and / fallax�pezizoides lineages of Helvella s.s. are shortly commented upon. Further we include a discussion of the distribution
of species in the Nordic region based on a large set of studied collections. The ecological versatility and variable
geographic patterns of these species indicate that cryptic species may have contrasting ecology in their local habitats.
... Jusqu'ici, le genre Helvella n'avait pas été réellement étudié au Monténégro. Pendant près de deux décennies, nous avons récolté un abondant matériel, dont seulement une petite partie a été examinée (Perić 1999(Perić , 2010Perić & Perić 1996, 1997a,b,c, 1999, alors que la partie la plus importante fera l'objet de nos futures occupations. ...

Abbott in Abbott & Currah harvested in Montenegro (H. albella, H. atra, H. branzeziana, H. elastica, H. elastica f. minima ad int., H. ephippium et H. latispora) are presented in this paper.
