摘要 我们利用形态学和质体 rbcL 基因测序研究了来自秘鲁中部的秘鲁叶霉 (Phyllophora peruviana) 的新鲜收藏品和同种型。在 rbcL 系统发育树中，P. peruviana 由三个遗传群体组成，形成一个分支。由于该 P. peruviana 分支与 Phyllophora 属有远缘关系，包括 Phyllophora Cripa 属，并且也与 Phyllophoraceae 中的其他属不同，因此我们将其描述为 Phyllophorella peruviana 属。等梳子。十一月和两个新物种，Phyllophorella humboldtiana sp。十一月和 Phyllophorella limaensis sp。十一月叶柄菌属与叶柄菌属的区别在于叶柄是压缩的，而不是圆柱状的柄，并且四孢子囊位于线囊壳中，而不是散布在叶状体表面的孢子囊。 Phyllophorella humboldtiana sp.十一月其特点是宽阔的叶片，边缘略呈叶状。利马叶藻十一月因其小而舌状的叶片而被识别。 Phyllophorella peruviana 的特征是由短的压缩柄产生的二分叶扇形叶片。目前，所有三种叶球菌仅产自秘鲁，但分布范围可能更广。
Abstract We investigated fresh collections and an isotype of Phyllophora peruviana from central Peru using morphology and sequencing the plastid rbcL gene. In the rbcL phylogenetic tree, P. peruviana consisted of three genetic groups, forming a clade. As this P. peruviana clade was distantly related to Phyllophora including the generitype Phyllophora crispa and also distinct from other genera in the Phyllophoraceae, we describe Phyllophorella peruviana gen. et comb. nov. and two new species, Phyllophorella humboldtiana sp. nov. and Phyllophorella limaensis sp. nov. The genus Phyllophorella is distinguished from Phyllophora by a compressed stipe rather than a terete stipe, and tetrasporangia in nemathecia rather than sori scattered over the thallus surface. Phyllophorella humboldtiana sp. nov. is characterized by broad blades with slightly lobate margins. Phyllophorella limaensis sp. nov. is recognized by its small, ligulate blades. Phyllophorella peruviana is distinguished by dichotomo-flabellate blades that arise from a short compressed stipe. All three species of Phyllophorella are currently known only from Peru but may be more widely distributed.
