Ascomata turbinate, napiform or ellipsoidal, up to 25 mm in the largest dimension, medium brown and slightly reddish in some parts to dull brown, often with deep cracks, sometimes slightly lobed, often with minute flattened polygonal warts visible on the surface using a hand-lens, glabrous, sometimes with an inconspicuous basal attachment.
Peridium 400-650 µm thick (including warts 80-250 µm high), with two distinct layers and a very variable structure. Outer layer ca 100 µm thick, pale brown, composed of hyphae to 13 µm diam with walls up to 2 µm thick, forming a textura angularis to epidermoidea, both types of structure sometimes being visible in the same section. Inner layer 300-550 µm thick, not clearly distinct from the gleba, slightly pigmented or nearly colourless when close to the gleba, usually composed of hyphae up to 16 µm diam, forming a textura angularis, often also with thinner hyphae about 8 µm diam, mixed with a few thicker (up to 12 µm diam), more pigmented, straight, septate hyphae with walls about 1.5 µm thick, forming a textura intricata.
Gleba pale yellowish-brown, solid with paler labyrinthine veins separating individual closed fertile chambers completely filled with asci and hyphae and lined with hymenium. Hyphae in the veins 4-6 µm diam, colourless, septate, forming a textura intricata, but, sometimes up to 16 µm diam and forming a textura globulosa. Paraphyses cylindrical, colourless, about 5 µm diam, with rounded, free, slightly swollen tips, the same length as the asci or often elongated and anastomosing with the paraphyses arising from the opposite side of the fertile chamber.
Asci cylindrical, tapering towards the base, 250-300 x ca 35 µm, with walls up to 1.5 µm thick, not turning blue in Melzer's reagent, 8-spored, often with 1-2 spores aborted.
Ascospores uniseriate within asci, globose, 18-25 µm diam excluding ornamentation, with walls up to 3 µm thick, often with one droplet in each ascospore; young ascospores smooth, colourless, becoming pigmented and ornamented with strongly cyanophilic warts when older; at first slightly pigmented with minute warts about 1 µm high and 1 µm diam at the base, later pale brown, with sparse hemispherical warts up to 1.5 µm high and 2 µm diam at the base.

Ab L. tesselato differt quod habet ascomata maioria, pallide brunnea, saepius turbinata et cum verruculis polygonalibus et applanatis; habet ascosporas, quoque, verruculis sparsis et irregularibus indutas. Ab L. vario differt quod ascomata habet nil tomentosa in quibus fertiles adsunt loculi glebae quos complent paraphyses, asci et ascosporae etiam in senectute.

Typus: New Zealand: South Island, Otago, McLenan, bank of an estuary in sandy soil, 1 April 1939, s. coll. (holotype, K). Some ascomata parasitized by Microthecium geoporae (Obermeyer) Höhnel and eaten by insects.
