[email protected] Key words: Abstract: Phylogenetic analyses of 115 newly collectedHelvella specimens from Spain using three genetic markers [heat Helvella shock protein 90 (hsp), RNA polymerase II second largest subunit (rpb2) and the nuclear large subunit ribosomal DNA molecular phylogeny (LSU)] confirm the assignment of the Spanish collections to one Dissingia and 30 Helvella species. The analyses were new taxa supplemented with an additional sample of 65 Spanish and extralimital Helvella specimens from the fungaria of Oslo Pezizales (O), Trondheim (TRH), Copenhagen (C), Uppsala (UPS), Stockholm (S) and Venice (MCVE). Nine species are described as new, i.e. Helvella fuscolacunosa, H. hispanica, H. iberica, H. inexpectata, H. neopallescens, H. phlebophoroides, H. poculiformis, H. retinervis, and H. terricola. We present photographs of a selection of fresh specimens and provide descriptions of all species of this diverse South European Mediterranean element of the genera in Europe.
