“…In spite of its well-established morphological features, Nostoc has been proven to be genetically heterogeneous, and several genotypic groups were shown to fall outside of the 'Nostoc sensu stricto' clade based on 16S rRNA gene phylogeny (Hrouzek et al 2005, Rajaniemi et al 2005a, Papaefthimiou et al 2008, Lukešová et al 2009, Silva et al 2014. Therefore, the genus Nostoc has been proposed to be amended in consideration of phylogenetic data, and some Nostoc-related morphotypes have been established as new genera including Mojavia, Desmonostoc, Halotia, Komarekiella, Aliinostoc, Compactonostoc, and Minunostoc (Řeháková et al 2007, Hrouzek et al 2013, Genuário et al 2015, Bagchi et al 2017, Hentschke et al 2017, Cai et al 2019a, 2019b.…”
