Vulcanochloris Vančurová, Peksa, Němcová & Škaloud.

Vulcanochloris is morphologically very similar to its sister genus Asterochloris (Fig. 4), but it differs in the presence of spherical incisions within the pyrenoid (Vančurová et al. 2015). Vulcanochloris is also distinct by its ecological preferences, tolerating warmer and drier climatic conditions (Vančurová et al. 2018, 2021). The genus comprises three species ( V. canariensis, V. guanchorum and V. symbiotica) isolated from the lichen Stereocaulon vesuvianum growing on igneous rocks. As this genus has only recently been described, not many publications describing its free-living status. Moreover, it is quite possible that free-living Vulcanochloris species were mistaken as species of Trebouxia and Asterochloris . Environmental sequencing has revealed the presence of this genus in the soil of the French Alps (Stewart et al. 2021).
