Abstract
Type material of two Australian species: Trichocolea minutifolia Steph. and T. wattsiana Steph. is critically reviewed. On the basis of morphological observations both species are considered to be conspecific with T. hatcheri E.A.Hodgs., a species distributed in Australia and New Zealand. Detailed descriptions and illustrations based on the holotype are also provided for T. rigida R.M.Schust., the species newly confirmed on Macquarie Island. The worldwide key to the species of Trichocolea is given for the first time.
