Aglaophyllum pulchellum (Harvey) Kützing 1869: 2, p1. 5a, b.

Thallus (Fig. 57A) medium red, tufted, 3–5 cm high, subdichotomously and complanately branched with branches of even width, 3--6 mm broad, 2–5 mm apart, with strongly crispate to convolute margins, axils rounded; veins absent. Holdfast probably discoid; epiphytic. Structure. Growth marginal (Fig. 57C) without apical cells; mature cells (Fig. 57B) angular in surface view, isodiametric to slightly elongate, 35–55 µm across, often in transverse rows. Blades mostly tristromatic, polystromatic basally, cortical cells equivalent (Fig. 57E). Cells multinucleate; rhodoplasts discoid.

Reproduction: Gametophytes unknown.

Tetrasporangial sori (Fig. 57D, E) scattered, rounded, 0.5–1.5 mm across, with tetrasporangia subspherical to ovoid, 50–90 µm across.

Lectotype from King George Sound, W. Aust. (Harvey); in TCD (Harvey, Trav. Set 60); isolectotypes Alg. Aust. Exsicc. 295B, in TCD, MEL, 584158, NSW, 8645, 8646 and AD, A18302.

Selected specimens: King George Sound, W. Aust., (Harvey) and Ocean Reef Marina, Perth, W. Aust., 6 m deep (O'Brien & Millar, 9.xii.1980; AD, A68279 and in MELU).

Distribution: King George Sound and Rottnest I., W. Aust. (Harvey).

Taxonomic notes: The above description is based on Harvey's type specimens from King George Sound, W. Aust. and on AD, A68279, which is probably N. pulchellum. The species is otherwise little known, but in form is similar to Haraldiophyllum nottii from SE Australia, which differs in having entire, straight, margins in contrast to the strongly crispate margins of N. pulchellum. Further collections and study of N. pulchellum are clearly desirable to place it generically.

Millar (1990, p. 422) referred N. pulchellum to Myriogramme, on the basis of a cystocarpic specimen of Wilson in MEL (676687) from Port Phillip Heads, Vic., 10.i.1894. This specimen, however, has crenulate apices and margins and carposporophytes typical of Platyclinia; while slightly different in habit, it is now placed under Platyclinia crenulata Womersley.
