Name derivation:

|

Classification:
|
||||
Basicladia W.E.Hoffmann & Tilden, 1930; 4 of 8 species descriptions are
currently accepted taxonomically (Guiry and Guiry 2014).
Order Cladophorales; Family Pithophoraceae
The
green algal genus Basicladia W. E. Hoffman
& Tilden suggested for synonymy in Cladophora
Kütz. by van den Hoek is reconfirmed as a genus based on the distinct
basal system and the primarily epizoic habit associated
with freshwater turtles (Garbary 2010). |
||||
Morphology:
|
||||
Green sparsely-branched
trichome found on the dorsal carapace of aquatic
turtles. Any branches are mainly near the basal cell, itself attached to the
turtle shell by a "holdfast" of cells and a
cement. Cells in the upright trichomes
become wider and shorter toward the apex. |

Habitat:
|
||||
Attached to the shells of turtles and
some snails; occasionally other hard substrates. Basicladia emedii
sp. nov. is described
based on material from six streams in Paraná and Rio Grande do Sul States of Brazil. This is the second species of Basicladia recorded from South America. The new
species is distinguished based on small filaments with short and wide basal cells
of upright axes. It is the second of six species with an epilithic
habit and is not associated with either snail shells or turtle carapaces
