Lichen succession on leaves of Wilkiea macrophylla in southeast Queensland

Abstract

Pioneer foliicolous lichen species on the leaves of Wilkiea macrophylla are Tricharia albostrigosa and Sporopodium xantholeucum which appear to grow best as isolated thalli. These are gradually replaced by spreading species such as Porina epiphylla, P. impressa, and by discrete but apparently competition-resistant species such as Mazosia melanophthalma. Where leaf damage has occurred, Strigula subtilissima and S. complanata are present around the wound margins. Tricharia albostrigosa and Strigula complanata are new records for Australia. -from Author
