Burrowsia

Burrowsia is a genus of the lichen family Caliciaceae. It is monospecific, containing the single crustose lichen Burrowsia cataractae. Both the species and the genus were newly described to science in 2020 by Alan Fryday and Ian Medeiros. Burrowsia cataractae is known from only a single location in Mpumalanga, South Africa. The lichen forms grey to greenish-brown crusty patches on permanently moist quartzite rocks in the spray zone of Calodendrum Falls, where it occupies a cool, humid microhabitat within shaded ravine forest. Molecular analysis confirms that Burrowsia represents a distinct evolutionary lineage within the Caliciaceae, separated from other related genera by its unusual ascospore structure and distinctive ascus features. ...read more on Wikipedia.
