Fig. 1. a, Spongocladia vaucheriaeformis: filaments from the upper part of the thallus 
of a plant from Mauritius. X 45. b, Cladophoropsis membranacea: a part of the cushion- 
like thallus of a plant from the Virgin Islands. About X 5. (From Bprgesen, 1948 and 
1905, respectively.) 
veals that up to the present some 19 species 
have been accredited to Cladophoropsis. They 
are: C. brachyartra (Sved.) Bprgesen (1905); 
C. fallax Schiffner (1933); C. fasciculata 
(Kjellm.) Bprgesen (1905); C. gracillima 
Dawson (1950); C. herpestica (Mont.) Howe 
(1914), inch C. coriacea Yendo ( cf . Yamada, 
1944); C. howensis Lucas (1935); C. infes- 
tans Setchell (1924); C. limicola Setchell 
(1924); C. macromeres Taylor (1928); C. 
membranacea (A g.) Bprgesen (1905); C. 
modonensis ( Kiitz. ) Bprgesen (1905); C. 
pallida Baardseth (1941); C. peruviana Howe 
(1914); C. psyttaliensis (Schm.) Bprgesen 
(1905); C. rigida (Howe) Feldmann (1938); 
C. robusta Setchell et Gardner (1924); C. 
sundanensis Reinbold (1905); C. voluticola 
(Hariot) Bprgesen (1905); and C. Zollin- 
geri (Kiitz.) Bprgesen (1905). 
Considering the wide recognition which 
Cladophoropsis has received in the course of 
the past 45 years as contrasted with Spongo- 
cladia , which has been referred to in a com- 
paratively small number of publications, it 
would be advantageous to reject the latter 
name in favor of the former, and it is ac- 
cordingly proposed that Cladophoropsis be 
considered for conservation.
