本研究為探討台灣膠衣及貓耳衣屬地衣之多樣性，從2007 年11 月至2009 年4 月間之調查，共獲得四種新紀錄 種，包括C. rugosum、 L. burgessii、L. rugosum、及L. tenuissimum。皆對其可作為辨認之特徵進行觀察、描述與 照相，包括地衣體、裂芽、子囊盤、子囊、子囊孢子等特徵，以期能提供鑑定此類地衣之完整資訊。

The lichens in the genera Collema and Leptogium are characterized by having a soft gelatinous (when wet) thallus with a nitrogen–fixing cyanobacterium as the photobiont component belonging to the genus Nostoc. The aim of this study was to survey the diversity of lichen genera Collema and Leptogium in Taiwan. During the course of study from November 2007 to April 2009, four new records have been found. They were C. rugosum, L. burgessii, L. rugosum and L. tenuissi-mum. For the species obtained in this study, all the discernible characters, such as thallus, isidia, apothecia, asci and as-cospores were observed, described and photographed. It was expected that a clear guideline of identification can be es-tablished.
