Abstract
Morchella helvetica, sp. nov. (Morchella sect. Distantes) is a new species of true morels discovered in Switzerland. It is formally described in the present study using an integrative approach based on micro- and macromorphological characteristics, multilocus phylogenetics, and a brief description of its habitat. Molecular analyses clearly indicated that Morchella helvetica is a sister species to M. eximioides, M. angusticeps, and M. confusa. It can be distinguished by the two phylogenetic markers RNA polymerase II subunit 2 (RPB2) and translation elongation factor-1 alpha (TEF1-α). In addition, M. helvetica exhibits particular morphological features, notably the presence of pale hairs on the pileus, a mealy stipe, and darkening ridges when aging.
期刊介绍：
International in coverage, Mycologia presents recent advances in mycology, emphasizing all aspects of the biology of Fungi and fungus-like organisms, including Lichens, Oomycetes and Slime Molds. The Journal emphasizes subjects including applied biology, biochemistry, cell biology, development, ecology, evolution, genetics, genomics, molecular biology, morphology, new techniques, animal or plant pathology, phylogenetics, physiology, aspects of secondary metabolism, systematics, and ultrastructure. In addition to research articles, reviews and short notes, Mycologia also includes invited papers based on presentations from the Annual Conference of the Mycological Society of America, such as Karling Lectures or Presidential Addresses.
