Notes: Accepted as Coltricia strigosa.
This is a highly characteristic species in Coltricia with small, strigose basidiocarps and subglobose
spores of variable size, measuring 4.5-7 x 4-6 µm. In Melzer's reagent, spores show a negative
reaction, unlike those of some other Coltricia species which are weakly dextrinoid.

Description: Hymenophore annual or reviving a second season, solitary or caespitose, attached by a central stem. Pileus orbicular, convex, not umbilicate, 1-5 cm. diameter, 2-5 mm. thick; surface at first fawn, becoming chestnut-brown, not or vaguely zoned, strigose with coarse vertical hairs in the centre, hairs radiately arranged peripherally, cuticle wanting; margin usually bluntly rounded, plane, entire; hymenial surface decurrent, chestnut-brown or cinnamon, sterile margin lighter in colour, 1-5 mm. wide, dissepiments not toothed; stem to 2 cm. long, 3-6 mm. thick, solid, cinnamon, coarsely or finely tomentose, usually fused at the base to a common mycelial mass. Context 2-3 mm. thick, cinnamon, of parallel hyphae radiately arranged; generative hyphae 5-7 μ thick, wall 0.5 μ, chestnut-brown, branched, septate. Pores angular, 0.2-0.5 mm. deep, ferruginous in section, 150-400 μ diameter, or 2-3 per mm.; dissepiments 75-200 μ thick, equal, apices slightly inflated, delicately velutinate. Basidia clavate, 12-16 x 5-6 μ, persistent. Spores subglobose, globose or slightly obovate, 5-7 x 5-6 μ, commonly 6 x 5 μ, smooth, tinted yellow.
Habitat: Growing solitary or usually caespitose on rich humus on the floor of forest or scrubland.
.
Distribution: New Zealand.
Notes: Separated from other species listed by the stout pileus with coarsely strigose surface, shallow pores and subglobose spores. It differs from obese forms of C.montagnei (Fr.) Murr. by the coarse strigose hairs of the pileus and smaller subglobose spores. A second crop of pilei had developed on the Oratia collection, suggesting that the species may survive a second season.
