MID CANTERBURY: Kowai Bush, on dead wood of Nothofagus solandri var. cliffortioides, 8 Apr 2001, PDD 72980; Arthur’s Pass, dead twig of Nothofagus solandri var. cliffortioides, 3 Feb 2002, PDD 75007; Lewis Pass, St James Walkway, dead twig of Nothofagus menziesii, 2 Feb 2002, PDD 75005.

This description applies to the anamorphic Aegeritina. Occurs on the underside of decorticated wood in damp and semi-submerged conditions. The propagules are easily detached from the substratum, white, spherical, 100–300 µm diam. They consist of tightly intertwined, septate, clamped hyphae. The propagule has projecting cystidia, to 70 × 4.0 µm, which are encrusted with crystalline material

New record from New Zealand. The propagules consist of a ball of sparingly branched, sinuous hyphae, reminiscent of Spirosphaera but bearing clamp connections. The main diagnostic character is the presence of projecting, encrusted cystidia, which are also characteristic of the Subulicystidium teleomorph. See Eriksson & Ryvarden (1984) for a description and illustration of the holomorph from European material. Hyde & Goh (1999) provided a recent description of UK material. Anon. (1998–2004) and Abdullah (1980) provide earlier records of this material from the UK. The teleomorph, Subulicystidium longisporum, has previously been reported in New Zealand. However, this collection represents the first report of the anamorph, which is a frequent inhabitant of the aero-aquatic environment.

Hymenophore annual, membranous, adherent, effused forming small linear areas 5-15 x 1-2 cm; hymenial surface white, drying pallid cream, even, not creviced; margin thinning out, arachnoid, white, adherent. Context white, 100-200 µm thick, basal layer scanty, of a few parallel hyphae, intermediate layer of loosely arranged mainly ascending hyphae often branched at a wide angle, more freely in the subhymenium; generative hyphae 3-3-5 µm diameter, walls 0.2 µm thick, hyaline, with clamp connections, encrusted beneath the hymenium. Metuloids arising from the hymenium and hyphae of the intermediate layer, projecting to 60 µm, subulate with sometimes inflated bases, terminating in long-acuminate apices which often collapse, 60-112 x 4-5 µm, encrusted save at apices with flat tuberculate crystals, walls thinning towards apices. Hymenial layer to 30 µm deep, a lax palisade of basidia, paraphyses, and metuloids. Basidia subclavate, somewhat scanty, 20-26 x 5-6 µm, bearing 4 spores; sterigmata delicate, to 6 µm long. Paraphyses subclavate, somewhat scanty, 16-20 x 4-5 µm. Spores narrowly rod-shaped with rounded ends, sometimes vermiform or allantoid, 14-17 x 1.5-2.5 µm, walls smooth, hyaline, 0.2 µm thick.

DISTRIBUTION: North Africa, Europe, Great Britain, North America, West Indies, New Zealand.

HABITAT: Effused on bark or decorticated dead wood.

Recognised readily by the long rod-shaped spores often adhering in fours, and subulate metuloids projecting for about half their length and bearing flat tuberculate crystals.

TYPE LOCALITY: Tunisia.
