As of 2015, there were 26 known marine Verrucariaceae, distributed amongst the genera Hydropunctaria (6 species), Mastodia (1 sp.), Verrucaria (16 spp.), and Wahlenbergiella (3 spp.). [60] Several of these marine lichens have been investigated preliminarily to determine their suitability for use as bioindicators of coastal water pollution .
