Bryum renauldii was previously recorded from North America in USA and Mexico (Spence 2014), Central America in Belize, Honduras, Costa Rica (Allen 2002) and Cuba (Ochi 1980) and South America in Colombia (Churchill & Linares 1995), Bolivia (Churchill et al. 2009), and Brazil (Canestraro & Peralta 2022). This is the first reported for Argentina. The Argentinean plants exhibits distant leaves, with the apex obtuse, entire to obscurely serrulate; costae subpercurrent and margin bordered (1–2 lines of quadrate to rectangular cells). The species was found in the Colón Grande Island, one of the lower Uruguay River islands. This area is located in a transition region between a subtropical and a temperate climate. According to the Köppen-Geiger classification, it corresponds to a Cfa categorization, which implies humid climate with oceanic influence, without a marked dry season and warm summers (Aceñolaza et al. 2019). The vegetation corresponds to mixed gallery forest with Inga uraguensis Hook. & Arn., Nectandra angustifolia (Schrad.) Nees & Mart., Croton urucurana Baill., Pouteria gardneriana (A. DC.) Radlk. and Eugenia uruguayensis Cambess. (Rodriguez et al. 2018).Complete description and illustration of this species can be found in Ochi (1980), Allen (2002), Canestraro & Peralta (2022).
