Abstract

E. taylori is endophytic in certain brown and red marine algae. Its setae are probably absorptive in function since they develop in cultures in sea-water, but are replaced by erect filaments in 0.75 and 0.375 Detmer''s soln. in sea-water. The latter morphological change adds further exptl. support to Huber''s theory that hairs and setae of procumbent Chaetophora-ceae are reduced erect branches of the heterotrichous habit. The degree of reduction of erect branches corresponds in the genera Ectochaete, Ochlochaete and Phaeophila. Germination varies from epiphytic to endophytic, within the genus, in Endoderma and Ectochaete, and within the species in Phaeophila dendroides.
