Highland Biological Recording Group. Holly Speckle (Trochila ilicina) is a fungus that only grows on dead (brown) leaves of Holly. Its appearance varies depending on the state of maturity, but it is easily recognised from the distinct fine (<1mm diameter) dark speckling on the upper side of the leaf only. Visit the HBRG 'TRY' page to download a full profile for the fungus and please let either Scottish Fungi or HBRG know about your finds (we'll pass the records to each other and to the Fungus Record Database for Britain and Ireland). There are two other species of Trochila in Scotland - Trochila laurocerasi, which is found on Cherry Laurel, and Trochila craterium, found on Ivy.
