Thallus (Fig. 53C) medium red-brown, with a perennial, branched, basal stalk, becoming relatively massive and showing growth rings in older parts, (2–) 5–15 cm high and 4–10 (–20) mm thick, compressed above, bearing 1–5 fronds from the apex of each branch. Fronds probably seasonal, expanding rapidly from the stalk apices, 5–26 cm long and 5–30 cm broad, 120–300 µm thick, complanate, foliose and variously branched with the margin usually becoming deeply indented and lobed, with the surface conspicuously mottled. Holdfast 2–10 (–30) mm across; epilithic. Structure of a relatively thin cortex 2–5 cells thick, outer cells 3–5 µm across and slightly elongate in section, with ovoid inner cells (becoming separated and slightly stellate), and a lax filamentous medulla of transverse and irregular filaments 2–4 µm in diameter, becoming moderately dense in older parts and with numerous prominent refractive ganglionic cells. Rhodoplasts discoid to elongate, several per cell.

Reproduction: Carpogonial branch ampullae not seen. Auxiliary cell ampullae (Fig. 54D) in the inner cortex, subspherical, with numerous fairly long secondary filaments forming a prominent ampulla, converging above. Carposporophyte with a persistent basal auxiliary cell and 2–3 lobes of carposporangia, with a slight ampullary involucre and small ostiole. Spermatangia unknown.

Tetrasporangia (Fig. 54E) scattered, cut off from outer cortical cells which divide to form irregular rows of 1–3 cells surrounding the sporangia, 16–25 µm long and 10–16 µm in diameter, cruciately divided.

Type from Fremantle, W. Aust. (Harvey, Tray, set 174); holotype in TCD; slide in AD, A18513.

Selected specimens: Geraldton, W. Aust., drift (Borowitzka, 22.iv.1979; MELU, A39615). Port Denison, W. Aust., drift (Kraft 3969, 14.xii.1971; AD, A41790). Cape Vlamingh, Rottnest I., W. Aust., 14 m deep (AIMS-NCI, Q66C 2703-F, 15.iii.1989; AD, A59774). Green I., Rottnest I., W. Aust., 5 m deep (Engler, 6.ix.1979; AD, A51043). Hamelin Bay, W. Aust., 6 m deep (Kraft & Ricker, 13.viii.1979; MELU, K6969). Seamount off Cannan Reefs, S. Aust., 22–30 m deep (Branden, 22.i.1991; AD, A61203).

Taxonomic notes: The morphology and structure of C. kallymenioides have been described by Scott et al. (1982), emphasising the perennial woody stalks (rarely collected except with SCUBA) which grow vertically or horizontally from the roofs or sides of undercuts (Kraft, pers. comm.). While the structure and reproduction agree with Cryptonemia, the thallus is more foliose and more mucilaginous than the more typical species (e.g. the type and C. undulata). C. kallymenioides reaches the southern Australian region in a probable (but sterile) specimen from Cannan Reefs, S of the Isles of St Francis, S. Aust. Records of Chapman (1979, p. 289) from Borneo and New Zealand are clearly incorrect.
