摘要

本氏Lamprospora benkertii被描述为一个基于格鲁吉亚、德国、挪威、斯洛伐克和瑞士的新物种。其特征是没有流苏状边缘的橙色顶端古猿，球形子囊孢子，具有海鞘型纹饰，包括形成网状的强脊和由初级网状网中的细脊形成的次级网。这种真菌感染脆口菌的根瘤。LSU和EF1α序列分析支持了新物种的描述。本氏Lamprospora benkertii与其他具有海生孢子型或类似子囊孢子装饰的Lamprosporia物种进行了比较：L.ascoboloides、L.cailletii、L.dicranellae、L.funigera、L.hispania、L.irregulariata、L.leptodictya、L.norvegica、L.paechnatzii、L.seaveri。我们还提供了这组物种的最新密钥，以及基于我们从几个集合中观察到的更完整的L.hispania描述。为L.hispanica、L.leptodictya、L.norvegica和L.paechnatzii提供了新的宿主特异性数据。

Lamprospora benkertii sp. nov., and an evaluation of Lamprospora spp. with seaveri-type ascospore ornamentation

Lamprospora benkertii is described as a new species based on collections from Georgia, Germany, Norway, Slovakia, and Switzerland. It is characterized by orange apothecia without a fimbriate margin, globose ascospores with a seaveri -type ornamentation comprising strong ridges forming a reticulum and a secondary reticulum formed by fine ridges within the meshes of the primary reticulum. The fungus infects rhizoids of Trichostomum crispulum. Delineation of the new species is supported by LSU and EF1α sequence analyses. Lamprospora benkertii is compared with other Lamprospora species with a seaveri -type or similar ascospore ornamentation: L. ascoboloides, L. cailletii, L. dicranellae, L. funigera, L. hispanica, L. irregulariata, L. leptodictya, L. norvegica, L. paechnatzii, L. seaveri. We also present an updated key for this group of species as well as a more complete description of L. hispanica based on our observations from several collections. New host specificity data are provided for L. hispanica, L. leptodictya, L. norvegica, and L. paechnatzii.
