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).
