摘　　要：Orthotrichum tortifolium Lewinsky,作为一个不丹特有种,最近在中国首次发现。2021年4月,我们在四川贡嘎山自然保护区采集到2份标本。它们的形态与Orthotrichum tortifolium的模式基本一致。该种的主要鉴定特征是扭曲或卷缩的叶片和具很高基膜的内蒴齿。而且,这2个特征在木灵藓属(Orthotrichum)中都较罕见。我们在此提供了详细的形态描述和照片,并讨论了它与相似种的主要区别。Orthotrichum tortifoliumLewinsky,an endemic to Bhutan,was recently first reported in China.Two specimens were collected by us in April,2021 from Gongga Mountain Nature Reserve,Sichuan.The morphology was well consistent with the type of O.tortifolium.It was remarkably characterized by the flexuose to crisped leaves and the high basal membrane of endostome segments,which were rare in Orthotrichum.We provided detailed morphological description and photos here,and discussed its main differences from close species.
