摘要：我们利用质体 rbcL 序列和形态学检查研究了来自秘鲁的Phyllophoraceae 科物种。在这里，我们描述了 Acletoa tarazonae gen。 ＆sp。 11 月，其特征是在囊果周围存在次生髓质细胞、向下和向上定向的成生殖细胞首字母、以及髓质细胞上成生殖细胞细丝的线性排列。 Acletoa tarazonae 始终与 Ahnfeltiopsis vermillaryis 和 Chilean Gymnogongrus sp. 形成一个分支，并且该分支与 rbcL 系统发育中的Phyllophoraceae 中的其他属不同。我们还描述了Phyllophoraceae 的一个新种，Gymnogongrus caespitosus sp。 11 月，来自秘鲁北部，其特征是半刚性且扁平的叶状体、狭窄的分枝、缺乏毛细胞以及浸入单个腔中的囊果。 Ahnfeltiopsis concinna 与 Ahnfeltiopsis durvillei 没有区别，并且在 rbcL 系统发育中始终归入 Gymnogongrus sensu stricto 属。 Gymnogongrus durvillei 梳子的新组合。十一月是在 A. durvillei 的基础上制成的，A. concinna 与 G. durvillei 合并。
Abstract: We investigated species in the family Phyllophoraceae from Peru using sequences of the plastid rbcL sequences and morphological examination. Here we describe Acletoa tarazonae gen. & sp. nov., characterized by the presence of secondary medullary cells around cystocarps, gonimoblast initials that are downwardly and upwardly directed, and a linear arrangement of gonimoblast filaments on medullary cells. Acletoa tarazonae consistently formed a clade with Ahnfeltiopsis vermicularis and Chilean Gymnogongrus sp., and this clade was distinct from other genera in the Phyllophoraceae in the rbcL phylogeny. We also describe a new species of the Phyllophoraceae, Gymnogongrus caespitosus sp. nov., from northern Peru, characterized by a semirigid and flattened thallus, narrow branches, absence of hair cells, and cystocarps immersed in a single cavity. Ahnfeltiopsis concinna was not distinct from Ahnfeltiopsis durvillei, and consistently grouped in the genus Gymnogongrus sensu stricto in the rbcL phylogeny. A new combination of Gymnogongrus durvillei comb. nov. was made on the basis of A. durvillei, and A. concinna was merged with G. durvillei.
