Descriptions
Distribution.-Beech Forest, York Bay, Wellington, N.Z. (E. H. Atkinson, 30 m., 5/10/10. Type, May, Aug., 1922; E. J. Butler, G.H.C., 29/7/23), Dun Mt., Nelson (J. C. Neill, 30/5/23). Collections in the herbarium of the writer. Nos. 873, 923, 1208.
Peridium violet, depressed-globose, base truncate, deeply excavated, up to 7 cm. high, and 7 cm. broad, smooth, glabrous, polished, viscid; drying pallid-brown, becoming rugulose. Stipe pallid-violet, tinted yellow at the base, stout, 3-9 cm. long, 10-20 mm. wide at the base, tapering to the apex, fibrillose, minutely striate, hollow; columella slightly expanded at the apex. Gleba pallid ferruginous, labyrinthiform or cellular, cells 1-2 mm. long, numerous, dissepiments thick. Spores coarsely verruculose, chestnut-brown, ovate, one end rounded, the other pointed, 12-17 x 8-11 µ, epispore thin.
Habitat. Solitary on the ground in beech forest. (Nothofagus sp.).
Peridio violaceo, depresso-globoso, 7 cm. alto, 7 cm. lato, leve, glabro. Stipite pallido-violaceo, 3-9 cm. longo, 10-20 mm. crasso, fibrilllloso, striato, excavato. Gleba pallido-brunnea, cellulosa vel labyrinthiforma. Sporis grosse verruculosis, castaneo-brunneis, ovatis, 12-17 x 8-11 µ.
This species is characterised by the large size and violet colour of the peridium. It is not uncommon in a certain beech forest near Wellington, appearing there during the winter months, usually after heavy rain. At first it is buried in the ground, often in clayey soil, but as it approaches maturity it appears on the surface. When submerged it is a pallid white, but as soon as it is exposed to the light it changes colour; that this change is effected by light is obvious when a specimen that has partially emerged is examined, for it is then seen that the portion above the ground is violet, but that the remainder is white. The peridium is deleidedly viscid when fresh.
In its younger stages the plant is readily confused with Gallacea scleroderma (Cke.) Lloyd, as in colour and hypogeal habit it resembles this species; but when the peridium is sectioned the plants may be readily separated.

The fruitingbodies of this common fungus in New Zealand can vary considerably in shape and size as is shown in Fig. 3 a-d. Excellent descriptions have been given by Cunningham (1942: 84), Heim (1951: 129) and Singer & Smith (1958: 212) but the white veil remnants scattered along the margin of the gastrocarp or along the stipe hitherto have been overlooked. All collections kept in our herbarium showed in fresh conditions obvious veil remnants, which cover parts of the peridium and still more frequently the lower portion of the stipe.
Spores 12-1.5 x 7.5-9.5 µm, ellipsoid to ellipsoid-oblong, rust brown, verrucose, mostly axially symmetric, perisporium poorly developed or lacking. Basidia 35-50 x 10-14 µm 4-spored. Cystidia absent. Epicutis consisting of interwoven, gelatinised, hyaline hyphae (2-6 µm diam.) forming a cutis, hyphae of subcutis cylindrical, with thin-walled membrane and epimembranous pigment. Clamp connections present, but sometimes rare.

On ground amongst litter of Nothofagus fusca, N. menziesii, N. solandri, N. cliffortioides. New Zealand.
Cunningham 1942: pl. 8, fig. 1, 2); Heim (1951: 129).
This species represents one of the most common fungi in all types of New Zealand Nothofagus forests. Th. porphyreum (Cunningham) also occurs during mild winter and its purple colours have attracted the attention of mycologists and naturalists alike.
