Description: A variety of C. tenax very common on lime mortar distinguished by its thick, smooth, cushion-like lobes, more swollen than in the var. tenax. When dry, it appears tightly folded and strongly attached to the substratum. Discs are frequent. Many of the Irish records of Collema tenax s. lat. will be this variety. Western Ireland, mainly.

Key Identification Features:

• Thallus of smooth convex lobes forming neat rosettes, much swollen
• Lobes smoother and plumper than var. tenax and never subdivided into a ‘shock’ of cylindrical processes as in var. ceranoides.
