Ocellularia neoperforata


Ocellularia neoperforata is a rare species of corticolous lichen in the family Graphidaceae. Found in Malaysia, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected by the second author from Gunung [Mulu National Park] at an elevation of about ; here, it was found in a heath forest growing on a young tree. It is only known from the type collection at the type locality. The lichen has a shiny and smooth, greenish-grey thallus with a dense cortex and a white medulla. Its ascospores are trans-septate, narrowly ellipsoid, and measure 11–15 μm long. It contains fumarprotocetraric acid, a secondary compound. Ocellularia perforata is a lookalike species after which O. neoperforata is named. In contrast to the latter lichen, it has larger ascospores, less emergent apothecia, and contains protocetraric acid.
