Notes: The description of Cunningham (1965: 55) is satisfactory. The species was transferred to
Antrodiella Ryv. & Johans. by Ryvarden & Johansen (1980) because of the dense basidiocarp,
dimitic hyphal system, and small spores.

Description: Hymenophore annual or perennial,
adherent, coriaceous, effused forming irregular areas 8-15 x 4-8 cm, 5-10 mm
thick. Hymenial surface at first white, drying cream or pallid yellow, sometimes
tinted orange, not creviced, even; margin thinning out, irregular,. concolorous,
1-10 mm wide, fibrillose, adherent. Pores obscurely stratose in old specimens,
slightly glancing, round, 7-9 per mm, 75-100 µm diameter, to 8 mm deep;
dissepiments entire, 30-100 µm thick, commonly 50 µm, acuminate, even or
slightly velutinate. Context white, to 1 mm thick, 200 µm or less in old plants,
of densely intertwined hyphae, embedding a few scattered crystals; skeletal
hyphae 2.5-5 µm diameter, walls 1-1.5 µm thick, aseptate, sparsely branched,
naked; generative hyphae 1-1.5 µm diameter, walls 0.1 µm thick, branched,
septate, with scanty clamp connections. Hymenial layer to 10 µm; deep, a scanty
palisade of basidia and paraphyses. Basidia elliptical, or subclavate, 4-6 x 2-4
µm, soon collapsing, bearing 4 spores; sterigmata erect, slender, to 4 µm long.
Paraphyses obovate, cylindrical, or a few subclavate, 4-6 x 2-3 µm. Spores
allantoid or sublunate, 2.5-3 x 0.75-1 µm, walls smooth, hyaline, 0.1 µm thick.
Habitat: HABITAT: Decorticated decayed fallen branches and trunks, associated
with a white rot.
Distribution: DISTRIBUTION: New Zealand.
Notes: Characterised by the
firm and dry coriaceous texture, light colour, small pores with thin
dissepiments, obscurely stratose in old specimens, sparsely branched aseptate
skeletal hyphae, delicate generative hyphae, and allantoid spores of small size.
Most collections are sterile, save near margins, and even in fertile plants
basidia are scattered and inconspicuous.
The species illustrates
the weakness of trying to establish a genus such as Perenniporia upon
the presence of stratose pores. In different specimens pores may be in a single
layer, of several seasons' growth but continuous, or show definite strata
indicated by slight changes in shape or colour.

Description: Hymenophore effused, to 15 x 8 cm., 5-10 mm. thick, firm, dry and woody, at first white, drying
cream or pallid yellow, sometimes tinted orange; surface even, not toothed, slightly glancing;
margin tapering, irregular, concolorous, from 1 mm. to 10 mm. wide, byssoid. Pores obscurely
stratose in old specimens, cream in section, round, to 8 mm. deep, 75-100 µ diameter, or 7-9 to
mm.; dissepiments 30-100 µ thick, commonly 50 µ, apices acuminate, even or slightly
velutinate. Context white, to 1 mm. thick, often 200 µ or less in old plants, hyphae loosely
woven, not cemented, similarly arranged in dissepiments, crystals few and scattered; skeletal
hyphae 2.5-5 µ thick, lumen 1 µ, hyaline, not staining, aseptate, sparsely branched; generative
hyphae to 1.5 µ thick, delicate walled, branched, septate, contents staining, clamp connections
present, scanty. Basidial type clavate, basidia elliptical or clavate, staining, 4-6 x 2-3 µ, soon
collapsing. Spores allantoid, appreciably curved, 2.5-3 x 0.75-1 µ, smooth, hyaline.
Distribution: New Zealand.
Notes: Differentiated by the firm, dry, woody texture and light colour of the hymenophore, small pores
with thin dissepiments, sparingly branched aseptate skeletal hyphae, and allantoid small spores.
It somewhat resembles P.subacida Peck, but differs in the smaller pores, cream colour, spores
(those of P.subacida being ovate, 3-4.5 x 3-4 µ), absence of cystidia and aseptate skeletal
hyphae.
