Notes: Worldwide in tropical environments. In California, collections from 1957-1959 by E.Y. Dawson in UC from Big Sycamore Canyon, Ventura Co.; just north of Dana Point, Orange Co.; just east of Lechuza Point, Los Angeles Co.; recent collections in UC from San Miguel Island, San Clemente Island; San Nicolas Island (USNM15259, USNM80361, USNM15260).

Status: This should be considered a tentative identification until it can be confirmed with molecular methods.

Habitat: Mid-intertidal, in shallow caves or at shaded bases of seaweeds, often in exposed environments

Cladophoropsis Borgesen 1905

Thalli filiform, erect, Cladophora-like axes usually clumped, with rhizoidal attachment. Cells of axes multinucleate, with branches arising from distal ends at irregular intervals and remaining, at least for a time, in open connection with mother cell; chloroplasts reticulate to isolated with age, with numerous small pyrenoids.

Cladophoropsis fasciculatus (Kjellm.) Okam.

Siphonocladus fasciculatus Kjellman 1897: 36. Cladophoropsis fasciculatus (Kjellm.) Okamura 1907-42 (1921): 75; Dawson 1958: 65; Abbott 1972b: 259. C. coriacea Yendo 1920: 1.

Thalli filiform, caespitose to pulvinate, 2-3 cm tall, bluish-green, rigid when fresh; filaments 125-350 µm diam., profusely and variously branched and densely compacted; branches spreading, somewhat curved, the upper branches mostly longer than the lower, with frequent rhizoidal branches conjoining filaments; crosswalls sparse, not occurring at point of branch origin.

Reported in California, without habitat or depth, only from Lechuza Point (Los Angeles Co.) and Dana Point (Orange Co.). Type locality: Japan.

Notes: Wille, rather than Okamura, was the first author to use this binomial. The epithet should be fasciculata to agree grammatically with the generic name, which is feminine. This species was considered conspecific with C. zollingeri (Kützing) Reinbold by Yoshida et al. (1990), but subsequently was treated as an independent species by Yoshida (1998).
