Papenfussiella lutea Kylin 1940: 19, fig. 12B, pl. 3 fig. 7.

Phylum Phaeophyta – Order Chordariales – Family Chordariaceae

Selected citations: Lindauer et al. 1961: 227, fig. 51(3–5). Nelson & Adams 1983: 80, figs 3,4.

Thallus (Fig. 30B) medium to dark brown, mucoid, densely tomentose, attached by a small discoid holdfast 1–2 mm across, with one to a few long axes with several long laterals and often shorter branchlets, 10–40 cm long and 1–3 mm in diameter, epilithic. Medulla (Fig. 32A) dense, of longitudinal filaments 10–16 (–20) µm in diameter with cells L/B (4–) 6–12 (–15), with only slight production of hyphae except when mature, when the medulla is covered by a weft of hyphal filaments 4–8 µm in diameter. Cortical filaments (Fig. 32A,B) produced directly from the outer medullary filaments near the branch apices, later from the weft of hyphae, of two lengths: shorter determinate filaments 100–250 µm and 10–20 cells long, slightly curved, cells (6–) 8–10 in diameter and L/B 1–2 (–4) above, narrower below; and longer (indeterminate) cortical filaments 1–1.5 mm and usually over 50 cells long, cells 15–20 µm in diameter and L/B 1.5–2 above, becoming narrower (6–8 mm in diameter and L/B 2–4) near their base. Phaeoplasts (Fig. 32C) several per cell, discoid, each with a pyrenoid. Phaeophycean hairs absent.

Reproduction: Sporangia arising directly from the outer medullary filaments or from the hyphal weft; thalli with only unilocular sporangia or with mainly plurilocular but a few unilocular sporangia. Unilocular sporangia (Fig. 32B) borne at base of cortical filaments, scattered or when well developed forming a well-defined layer outside the medulla, clavate to ovoid, (40–) 45–70 (–95) µm long and 15–30 µm in diameter. Plurilocular sporangia (Fig. 32D) terminating branched clusters of slender filaments, the whole forming a dense stratum (100–140 µm broad) at the base of the cortical filaments; sporangia 30–60 pin and 8–25 locules long, 3–4 µm in diameter.

Distribution: New Zealand (see Nelson & Adams 1983, p. 80). East coast of Tasmania.

Taxonomic notes: Type from Paihia, Bay of Islands, New Zealand (Lindauer, 6.xi.1937-"Algae Novae-Zelandicae Exsiccatae" No. 86); in LD, isotypes in other herbaria.

The Tasmanian specimens agree well with the New Zealand species. P. lutea appears to be rare on eastern Tasmanian coasts, but occurred in abundance on wave-washed, sand surrounded, rocks at The Gardens.

Lindauer et al. (1961, p. 228) also credited the South African P. laxa Kylin to New Zealand, but Nelson & Adams (1983, p. 82) place all New Zealand specimens under P. lutea.

However, some New Zealand specimens [e.g. from Motunau Point (Womersley, 15.i.1966; ADU, A29944)] do have considerably broader (22–26 µm) long cortical filaments than given for P. lutea and are more robust plants; they may represent a different entity.
