Algae erect, more or less cylindrical throughout, up to 15 cm tall; branching irregularly dichotomous; attached by discoid base of rhizoidal filaments. Branches cylindrical; in lower portions sometimes narrow and constricted at dichotomies; in midportions broadening; and in terminal portions sometimes swollen to club-shaped, up to 1.6 cm in diameter. Medulla filaments 23–45(–50) µm in diameter. Utricles slender, cylindrical to clavate, constricted below, giving upper portion spoon-shaped appearance, (460–)540–820(–1150) µm long by (70–)95–200(–290) µm in diameter, and in basal portion (30–)40–70(–112) µm in diameter; sometimes with secondary utricles; utricle apices blunt to dome shaped, outer end with hyaline, laminated, conical cell wall, (30–)50–85 µm thick; hairs and scars present.

Gametangia fusiform or cylindrical, (130–)200–270(–330) µm long by (40–)60–90(–125) µm in diameter; usually one per utricle, borne about (230–)280–390(–500) µm below the apices.

HABITAT. On rocks and tidal platforms, often exposed; mid intertidal to shallow subtidal, down to 10 m depths.

DISTRIBUTION. Gulf of California: Punta Pelícano (vicinity of Puerto Peñasco) to Guaymas; Bahía Concepción to Bahía de La Paz.
