Tiffaniella Doty & Menez 1960
Thalli filamentous, uncorticated, differentiated into basal portions bearing rhizoids with modified apices and erect portions of irregularly branched filaments with elongate multinucleate cells. Sporangial plants with polysporangia in irregular lateral clusters, each sporangium containing 8-32+ spores, or with tetrasporangia. Spermatangia in lateral, short to elongate heads, these variously arranged. Procarps formed on middle cell of 3-celled axis; 3 pericentral cells also produced (1 remaining functionless; 1 forming abaxial sterile cell, lateral, 4-celled carpogonial branch, and auxiliary cell after fertilization; and 1 forming second auxiliary cell). Both auxiliary cells fusing with fertilized carpogonium through connecting cell; fusion cell composed of fertile cells, axial cells, and 2 auxiliary cells, forming T-shaped gonimoblast; only terminal cells becoming carposporangia, each surrounded by gelatinous envelope; involucre lacking.

Spermothamnion snyderiae Farlow 1899: 74; Smith 1944: 322. Tiffaniella snyderiae (Farl.) Abbott 1971a: 349.
Thalli 2-5 cm tall, deep red; most branches unilateral or irregular, rarely with more than 3 orders of branching, all orders of nearly same diam.; basal rhizoids with expanded apices; cells in midsections (50)80-130 µm diam., 10-20 times as long; polysporangia in irregularly shaped, lateral clusters, broadly ellipsoidal, 75-90 µm diam., 95-110 µm long, with 8-32 spores; spermatangia dense in lateral branchlets, replacing adaxial branches; gonimoblasts rare, bilobate, 250-350 µm wide, flattened on top; first and second cells of fertile axis fusing with auxiliary cells; carposporangia ovate, 25-35 µm diam., 35-50 µm long, few per gonimoblast.
Locally abundant, saxicolous, low intertidal to subtidal (to 20 m), Wash. to Baja Calif., into Gulf of Calif. Type locality: Santa Cruz, Calif.
