摘要
Morchella helvetica，新种（Morchella sect.Distantes）是在瑞士发现的一种真正的羊肚菌新物种。本研究基于微观和宏观形态特征、多焦点系统发生学以及对其栖息地的简要描述，采用综合方法对其进行了正式描述。分子分析清楚地表明，Morchella helvetica 是 M. eximioides、M. angusticeps 和 M. confusa 的姐妹种。它可以通过 RNA 聚合酶 II 亚基 2（RPB2）和翻译延伸因子-1 α（TEF1-α）这两个系统发育标记来区分。此外，M. helvetica 还表现出特殊的形态特征，特别是绒毛上有浅色绒毛、蚧壳柄和老化时变黑的脊。
A new species of true morel from Switzerland: Morchella helvetica, sp. nov.
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.
