Topeliopsis acutispora is a species of crustose lichen in the family Graphidaceae.[1] It is found in New South Wales and southern Queensland (Australia), where it grows on bryophytes (i.e., mosses or liverworts).
Taxonomy[edit]
The lichen was formally described by lichenologist Klaus Kalb in 2001. The type specimen was collected from Cunninghams Gap in a cool temperate rainforest at an altitude of about 750 m (2,460 ft). The species epithet refers to the acute, or "pointy", shape of its spores.[2]
Description[edit]
The lichen has a thin, whitish-grey to greenish-grey, effuse (spread-out) thallus. Its apothecia are more or less spherical to barrel-shaped, measuring 0.4–0.7 mm in diameter. The pale pink excipulum, initially closed, later opens via a ragged pore (ostiole). Ascospores typically number eight per ascus (sometimes only four are present), and are hyaline, halonate, and measure 90–130 by 9–12 μm.[2]
Topeliopsis decorticans appears to be morphologically identical to T. acutispora; the two species are distinguished by major differences in their ascospores, including shape, size, septation, and number per ascus.[3]
