A new nivicolous species of Perichaena is described from the Andes in Argentina. The most conspicuous characteristics of Perichaena megaspora are the large spores and their ornamentation in the form of flattened warts. The 16-21 μm diam spores make the new species unique in the genus in which all other species have spores rarely reaching 15 μm diam. Twenty-two collections were found in the field during two consecutive years at 10 localities in Mendoza province Argentina, including one collection isolated from a moist chamber culture of ground litter. The new species was examined under stereomicroscope, light microscope and scanning electron microscope and micrographs of relevant details are included.
本文描述了产自阿根廷安第斯山脉的球冠藓属（Perichaena）一个新的附生种。大弹丝藓（Perichaena megaspora）最显著的特征是其大型孢子和疣状纹饰。16-21μm 直径的孢子使该新种在该属中独一无二，因为该属中所有其他种的孢子很少达到 15μm 直径。在阿根廷门多萨省的 10 个地点，通过连续两年的野外考察发现了 22 份采集样本，其中一份样本是从湿润室培养的地衣落叶中分离出来的。本文在体视显微镜、光学显微镜和扫描电子显微镜下对该新种进行了研究，并包括了相关细节的显微照片。
