在玻利维亚和哥斯达黎加采集到两个具有大型子座的竹红菌属新种。新种H. macrostroma sp. nov.，与其它大型子座的种H africana、H. gaertneriana和H.刚竹此外，从三个基因，大亚基核核糖体DNA（LSU），翻译延伸因子1-α（EF 1-α），RNA聚合酶II亚基1（RPB 1）的部分序列的系统发育分析，以确定该新种与其他种的竹红菌/座壳孢属。系统发育分析表明，H. macrostroma属于一个强支持的分支，包括H。africana，黑腹叶蝉H.竹红菌属（Hypocrella）的其他物种属于两个姐妹分支。描述了大基质肉座菌（Hypocrellamacrostroma），并命名为H. gaertneriana。
Two specimens of a new species of Hypocrella with large stromata were collected in Bolivia and Costa Rica. The morphology of the new species, H. macrostroma sp. nov., was compared with that of other species with large stromata, i.e. H africana, H. gaertneriana, and H. schizostachyi. In addition, phylogenetic analyses of partial sequences from three genes, large subunit nuclear ribosomal DNA (LSU), translation elongation factor 1-alpha (EF1-alpha), and RNA polymerase II subunit 1 (RPB1), were conducted to determine the relationships of the new species to other species of Hypocrella/ Aschersonia. Phylogenetic analyses show that H. macrostroma belongs to a strongly supported clade that includes H. africana, H. schizostachyi, and Aschersonia insperata, whereas other Hypocrella species belong to two sister clades. Hypocrella macrostroma is described and illustrated, and a lectotype is designated for H. gaertneriana.
