Mawsonia (fungus)

Both the genus and species were described by the American lichenologist Carroll William Dodge in 1948. The type specimen was collected from Possession Rocks on the Queen Mary Coast. The species epithet honours the collector of the type, the British naturalist Charles Turnbull Harrisson, who was part of the Australasian Antarctic Expedition (1911–1914) led by Sir Douglas Mawson. It is only known to occur at this location. As of 2016, no molecular sequence data are available for this little-known species.

The lichen has a {{lichengloss|fruticulose}} thallus, that is, smaller than a regular fruticose (bushy) thallus. It is black and prostrate, comprising dark, radiating {{lichengloss|dichotomous}} branches up to 75 μm in diameter. The {{lichengloss|photobiont}} partner is from the green algal genus Trebouxia, with cells measuring 7–8 μm in diameter. {{lichengloss|Ascospores}} produced by the lichen are broadly ellipsoid in shape, and measure 8–9 by 5.5–6 μm. They are {{lichengloss|polaribilocular}}, meaning they are divided into two components ({{lichengloss|locules}}) separated by a central septum with a perforation.
