摘要

摘要:提出了一种新种——长石桃(Harpidium longisporum)。它的特征是:微针形，主要是黑色的菌体，带有微藻，K+蓝紫色的色素部分，荚果果皮形成螺旋形的药囊，具有单核状的伞状，单状，厚壁的子囊和长s形，月形到镰形或不规则弯曲和扭曲的子囊孢子，生长在垂直的，间歇性湿润的片麻岩面的台阶上。Harpidium属现在在世界范围内包括四个物种，并根据所选标本，包括属简介，比较表和物种的关键。

Long sigmoid and twisted ascospores in the genus Harpidium: H. longisporum sp. nov., a synopsis of the genus and a key to the species

Abstract Harpidium longisporum is proposed as a new species. It is characterized by an areolate, mainly black thallus with trebouxioid algae, K+ blue-purple pigmented parts, pycnoascocarps forming aspicilioid apothecia, with moniliform paraphyses, unitunicate-rostrate, thick-walled asci and long sigmoid, lunate to falcate or irregularly curved and twisted ascospores, growing on steps of a vertical, intermittently moist, gneiss rock face. The genus Harpidium now comprises four species worldwide and, based on the selected specimens, a genus synopsis, a comparative table and a key to the species are included.

期刊介绍： The Lichenologist is the premier scientific journal devoted exclusively to the study of lichens worldwide. As the leading forum for the dissemination of new concepts and topical reviews, The Lichenologist reaches more scientists concerned with the study of lichens and lichen symbionts than any other single journal. All aspects of lichenology are considered including systematics and phylogenetics; molecular biology; ultrastructure, anatomy and morphology; secondary chemistry, effects of pollutants and use as bioindicators; biogeography. In addition to standard length research papers, the journal also publishes Short Communications and Book Reviews. A monthly issue may occasionally be devoted to papers deriving from a symposium.
