Abstract
Sphaeropezia leucocheila is described as a new species from New Zealand. Known from a single specimen, its fruiting bodies were consistently associated with a patch of dead and dying leaves in a liverwort colony that included several species of Lepidoziaceae. A phylogenetic analysis places this fungus in Sphaeropezia, a genus that includes several putative parasites of liverworts and mosses from the Northern Hemisphere.
