Callophyllis Kützing 1843

Thalli with circular to fan-shaped, much-divided blades arising from discoid holdfasts. Blades without midrib or veins, divided dichotomously, palmately, or pinnately, occasionally to many fine, narrow divisions. Margins of divisions smooth, crisped, dentate, or laciniate. Medulla of large, pseudoparenchymatous cells mingled with branched, pigmented filaments. Cortex 4 or 5 cells thick, the cells progressively smaller toward surface. Tetrasporangia embedded just below surface, cruciately divided, frequently germinating in place. Spermatangia in superficial patches, formed from outermost cortical cells. Plants procarpic. Plants either polycarpogonial or monocarpogonial with supporting cell becoming auxiliary cell. Cystocarp developing inward, surrounded by sterile tissue; carposporangial masses separated from each other by sterile filaments. Gonimoblasts unilaterally protuberant, each with 1 or more ostioles.

Callophyllis linearis (Kyl.) Abb. & Norr. Gracilaria linearis Kylin 1941: 22. Callophyllis linearis (Kyl.) Abbott & Norris 1965: 72.

Thalli 2-8 cm tall, purplish-brown, closely tufted, unequally dichotomously branched to 3 or 4 times, canaliculate, cartilaginous; apices acuminate, dentate, or bifurcate; tetrasporangia in irregular sori, occasionally spread beyond margins of sorus; spermatangia in small irregular patches in upper portion of plants; gonimoblasts few, to 1 mm diam., projecting but inconspicuous, borne on both surfaces of branches, some near margin.

Locally abundant on exposed headlands, saxicolous, low intertidal, Pt. Pinos (Paciļ¬c Grove; type locality), to 16 km south of Pt. Sur (Monterey Co.,), Calif; one subtidal (7 m) collection from off Pta. Banda, Baja Calif.
