1. Tremellodendropsis tuberose (Grev.) comb. nov.

Basonym: Merisma tuberosum Grev. 1825, t. 178.

Synonyms: Aphelaria tuberosa (Grev.) Corner 1950, p. 192 (see also for other synonyms and description) and 1953, p. 352.

Distribution: North Temperate, South Brazil, Borneo. No New Zealand specimens recorded.

Spores are given as (12-) 14–20 (–24) × (4-) 5–7 (–9μ), white, smooth, elongate ellipsoid, amygdaliform, subfusoid or subcylindrical. The lower limits of this spore range overlap with those of T. flagelliformis var. tasmanica but they can be separated on spore shape; those of the latter are more oblong and bluntly rounded, not tapered to a subacute apex or amygdaliform as are those of T. tuberosa.

(Corner has examined Borneo specimens and described them [private communication] as follows: Bt. Moeloe, Hans Winkler no. 570, 2:11:24 Herb. Hort. Bot. Bog. 3071: –5 cm. high caespitose, multifid below, becoming dichotomous above with elongate flagelliform tips; stem 2–3 mm. thick below; terrestrial: spores 12–14.5 × 7–8 5μ amygdaliform, subacute, the walls slightly but distinctly thickened, apicule 1μ: hymenium collapsed: hyphae 2–4μ wide, walls slightly thickened, clamped, monomitic.

Also Lianygagong, Herb. Hort. Bot. Bog. 5247: spores 13–16.5 × 7–9μ amygdaliform.

These should be included in T. tuberosa, because although slightly smaller in size, they have the distinct amygdaliform shape.)
