Hymenophore annual, coriaceous, solitary or caespitose, attached to the substratum by a lateral rarely excentric stem. Pileus fan-shaped conchate, or spathulate, 5-25 mm. x 10-20 mm. x 1-2 mm.; surface bay-brown, cinnamon, or chestnut-brown, becoming fuscous or black when old, radiate-striate with fine raised lines which are sometimes darker in colour, obscurely coned with bands of darker colour, or concolorous, silky when young, soon dull, cuticle wanting; margin acute, plane or slightly inturned, fimbriate, sometimes lacerate, undulate or even; hymenial surface even, at first fawn or bay-brown, becoming; ferruginous, finally umber, sterile margin 1-3 mm. wide, lighter in colour, dissepiments finely toothed; stem to 15 mm. long, 1-2 mm. thick, equal, solid, velvety, cinnamon, with a small bulbous base. Context chestnut-brown, 0.2-l mm. thick, of radiately arranged parallel hyphae; generative hyphae chestnut-brown, to 6 μ thick, wall 0.5 μ, branched, septate. Pores angular, ferruginous in section, 0.5-1 mm. deep, 100-200 μ diameter, or 3-5 per mm.; dissepiments 75-100 μ thick, equal, apex finely velutinate. Basidia clavate, 12-16 x 5-6 μ, persistent. Spores broadly elliptical, 6-8 x 4-5 μ, smooth, tinted yellow.

New Zealand.

Growing solitary or caespitose on clay soil in forest or scrub.

Characterized by the lateral (seldom excentric) stem, small dark-co1oured pores and radiate-striate dull pileus. The species is most closely related to C. cinnamomea, possessing a similar coloured finely radiate-striate pileus. It differs in the lateral stem, thinner walls of generative hyphae, smaller pores, and smaller spores. The habitat also is different, collections recorded having been taken from clay banks. Though lateral in most specimens, the stem is excentric in two or three, a condition which was seen in the fragmentary type at Kew.

Locality: New Zealand.
