A culture of Cirrosporium novae-zelandiae, the type species of a distinctive, monotypic coelomycete genus, was isolated from a specimen collected near the holotype locality in New Zealand. Light microscopic and environmental scanning electron microscopic observations confirm the details of the unusual meristem arthric conidium ontogeny presented in the protolog. For phylogenetic analysis, a dataset of 122 species representing nine classes of euascomycetes was assembled including sequences from nuclear small and large subunits (nc18S, nc28S) and mitochondrial small subunit (mr16S) ribosomal RNA and the largest and second largest subunits of RNA polymerase II (RPB1, RPB2). A five-gene phylogeny suggests that the fungus is phylogenetically related to the Eurotiomycetes. It sits alone on a long branch as a sister to the Mycocaliciales of the Mycocaliciomycetidae. Cirrosporium exhibits several morphological characters similar to those of members of the Mycocaliciales; however, the paucity of known anamorphs in this order does not offer any further clarification on possible relationships. It is clear that the rare and broadly distributed meristem arthric ontogenetic pattern is polyphyletic, occurring in widely separate groups of anamorphs of both the Ascomycota and Basidiomycota.
从新西兰模式种产地附近采集的标本中分离到一株新月弯孢菌的培养物，新月弯孢菌是一个独特的、单种的腔孢菌属。光学显微镜和环境扫描电子显微镜观察证实了原描述中独特的分生孢子节间关节分生孢子发生的详细特征。为了进行系统发育分析，我们构建了一个包含 122 个种的数据集，代表了九个有丝分裂真菌类群，包括核小亚基和大亚基（nc18S、nc28S）和线粒体小亚基（mr16S）核糖体 RNA 以及 RNA 聚合酶 II 的最大和第二大亚基（RPB1、RPB2）。五基因系统发育表明，该真菌在系统发育上与散囊菌目有关。它独自位于一个长枝上，是肉座菌目（Mycocaliciomycetidae）的姊妹群。新月弯孢菌表现出与肉座菌目成员相似的几种形态特征；然而，该目中已知的无性型较少，无法进一步阐明可能的关系。显然，这种罕见且广泛分布的分生孢子节间关节发生模式是多系的，存在于子囊菌和担子菌的无性型的广泛分离的群体中。
