Distributional note
"Chara gymnophylla is well represented in the Mediterranean: Greece, Cyprus, Albania, Italy (from north to south; Sicily), France, Spain and Portugal (Cunha, 1942; Corillion, 1957; Cirujano et al., 2008; Bazzichelli and Abdelahad, 2009; Manolaki et al., 2011; Langangen, 2014; Mouronval et al., 2015; Papastergiadou et al., 2015; Kashta and Miho, 2016; I. Soulié-Märsche pers. comm.). The record of C. rohlenae from Greece (Langangen, 2006) belongs to this species. In some cases, delineation from C. squamosa is not undertaken. Thus, voucher specimens have to be studied to confirm the evidence of C. gymnophylla. The species is less frequently reported from Western, Central and Eastern Europe. Records from Great Britain are based on specimens of C. vulgaris (Moore, 1986; Bryant et al., 2002; Bryant and Stewart, 2002; N. Stewart pers. comm.). In Germany, Migula (1889-1897) mentioned a few locations, but there is no extant evidence of C. gymnophylla (Arbeitsgruppe Characeen Deutschlands, 2016; I. Blindow pers. comm.). In Austria the species is reliably known from historical collections only (Hohla et al., 2020; W!). It is also reported for Czech Republic (Caisová and Gabka, 2009), Hungary (Filarszky, 1931), Serbia, Montenegro (, 2014; Blazencic et al., 2018), Romania (Stefureac and Ionescu Teculescu, 1967; W!), Bulgaria (Petkoff, 1913, 1914; Vilhelm, 1913), Ukraine (Crimea) (Borisova et al., 2016), and Russia (North%u2013East Black Sea region and North Caucasus; Hollerbach, 1950; Romanov et al., 2023; R. Romanov unpubl. data). Specimens from Portugal, Spain, Montenegro, Serbia, old collections from Greece, Cyprus, Austria, Bosnia and Herzegovina, Croatia, Romania, Russia, and Ukraine were confirmed (R. Romanov unpubl. data; Trbojevic et al., 2024). Specimens from Sardinia (Becker, 2019) were checked by R. Romanov and R. Becker and proved to be C. squamosa. Numerous records outside Europe are known (e.g. Corillion, 1957; Wood, 1965; Krause, 1997) but they might belong to different species, except reliable ones from North Africa (Muller et al., 2017), West Asia, incl. Caucasus (Ahmadi et al., 2012; Barinova and Romanov, 2015; Romanov et al., 2023; R. Romanov unpubl. data) and China (Han and Li, 1994; W checked by R. Romanov). The species is also known from South Africa and South America (Wood, 1978; Guerlesquin, 1981; Blindow et al., 2018)." (Romanov & Becker 2024). - (10 January 2025) - M.D. Guiry

Conservational note
"Chara gymnophylla has been assessed as LC (Least Concern) in the European Red List (see Chap. 9). According to Krause (1997) its dispersal capacity is limited by low fertility. The species is Critically Endangered in Czech Republic (Caisová and Gabka, 2009), and Vulnerable in Ukraine (Palamar-Mordvintseva and Tsarenko, 2004). Pollution, water abstraction, hydrological interventions and habitat destruction seem to be the most important threats. Eutrophication probably is an indirect threat, acting mainly via competition for light with phytoplankton and filamentous algae." (Romanov & Becker 2024). - (10 January 2025) - M.D. Guiry
