On rachis and pinnae of Dicksonia squarrosa, Dunedin, Berggren 400 (type).

Apothecia scattered, superficial, cupshaped with short cylindrical stalks, up to about 1 mm. diameter, white throughout, clothed with cylindrical, obtuse, often slightly capitate, thin-walled, septate, hyaline, finely granulate hairs which are 25-35 x 3-3.5 µ on the flanks but up to 75 x 5.5 µ at the margin. Asci cylindric-clavate, pore blued by Melzer's reagent, 8-spored, 70 x 6 µ; ascospores irregularly biseriate, fusoid, 14-18 x 2-2.5 µ; paraphyses lanceolate, up to 3 µ wide, with oily contents, protruding about 10 µ beyond the asci.

APOTHECIA 0.4-0.6 mm diam., stipitate, superficial, scattered or gregarious in small groups. DISC concave, greyish-white, surrounded by the raised margin and obscured in dried apothecia. RECEPTACLE translucent, pale grey or olive-grey, urceolate, the margin over-reaching the disc to constrict the aperture, fringed with whitish hairs, elsewhere clothed with short hairs which are scarcely visible in rehydrated apothecia but give them a pulverulent appearance when dried. STIPE cylindric, 100-300 µm high, 100-130 µm diam., also clothed with short hairs. HAIRS hyaline, cylindric-clavate, obtuse, those at the margin densely set, 50-70 x 4.5-5.5 µm, multiseptate, the walls thickened, granulate except towards the base. Hairs elsewhere scattered, shorter, 15-30 µm long, usually smooth. ASCI 63-75(-80) x 6-7 µm, 8-spored, cylindric-clavate, virtually sessile, apex conical, the pore conspicuously outlined blue in Melzer's reagent. ASCOSPORES 13.5-19.5 x 2.0-3.0, mean 15.8 (SD 1.4) x mean 2.4 (SD 0.2) µm, hyaline, fusoid, acute at the ends, straight, often inequilateral or slightly curved, frequently becoming 1-septate, biseriate. PARAPHYSES lanceolate, 3.5-4.5 µm, diam., septate only towards the base, containing numerous small guttules, exceeding the asci by 15-20 µm. SUBHYMENIUM indistinct. MEDULLARY EXCIPULUM composed in the stipe of parallel, vertically arranged, hyaline hyphae 2.0-2.5 µm diam., continuing into the receptacle as a narrow layer of parallel hyphae lying adjacent to the ectal excipulum but becoming interwoven in the centre of the receptacle in a layer 40-50 µm deep at centre, narrowing upwards and not differentiated from the ectal layer at the margin. ECTAL EXCIPULUM indistinct on the stipe, 25-30 µm thick on the receptacle, composed of broad, often subglobose, thin-walled, hyaline cells 8-15 x 5-12 µm, arranged at the base of the receptacle in irregular rows at a rather high angle to the surface, becoming narrower and prismatic, 4-5 µm diam. towards the margin and lying in chains curving round parallel to the surface. Margin extending beyond the surface of the disc by 70-80 µm.
