Description

Hymenophore annual, solitary or growing caespitose from a common base, laterally attached by a short stem 3-4 mm. x 2-4 mm., sometimes growing from a stem-like elongation of the upper surface, occasionally dimidiate and attached by a broad base, firm but brittle, entirely white when fresh, drying cream. Pileus shell-shaped, spathulate, bell-shaped or occasionally applanate, 1-3.5 cm. x 1.5-2 cm. x 1-2 mm.; surface white, becoming cream, smooth, dull, sometimes obscurely sulcate, cuticle 30-40 µ thick, of compacted hyphae with ends upturned and arranged in a close palisade; margin thin, acute, interned, entire or when old crenate or toothed; hymenial surface plane or concave, even, white, drying cream, dissepiments not toothed. Context white, 0.25-1 mm. thick, densely woven, separated from the pores by a delicate wood-coloured woven layer; generative hyphae 6-10 µ thick, lumen 2-3 µ, freely branched, septate, staining, clamp connections present, small. Pores round or angular, 0.2-0.5 mm. deep, white in section, 100-150 µ diameter, or 6-7 per mm.; dissepiments 50-150 µ thick, mostly 100 µ, of woven mainly parallel hyphae, slightly tapering, apex delicately velutinate. Basidial type merulioid, basidia cylindrical, 6-8 x 2-3 µ, arranged in a dense persistent palisade. Spores allantoid, 3-3.5 x 1-1.5 µ, smooth. hyaline.

Distribution

New Zealand.

Habitat

Growing on bark and decorticated wood of dead branches, usually solitary, sometimes caespitose, occasionally dimidiate.

Notes

The species is not closely related to others in this region possessing a monomitic hyphal system. It may be recognised readily by the merulioid basidial type, allantoid spores, glassy thick-walled intricately woven hyphae, definite though delicate cuticle, and white pileus. The lateral stem may be reduced to an expansion of the base, or lacking when plants are dimidiate and sometimes imbricate.

Description

Hymenophore annual, ceraceous, solitary or caespitose from a common base, attached by a narrow lateral base or pendent from an umbo. Pilei conchate, spatulate, campanulate, or applanate, 0.5-3.5 cm wide, 0.5-2 cm radius, 1-2 mm thick; pileus surface white, drying cream, glabrous, even or sometimes obscurely radiately sulcate; cortex to 40 µm thick, a close palisade of partly cemented hyphae with rounded ends; margin acute, inturned, entire or crenate when old; hymenial surface plane or concave, even, white, drying cream. Pores white in section, round or angular, 6-7 per mm, 100-150 µm diameter, 0.2-0.5 mm deep; dissepiments 50-150 µm thick, most about 100 µm, slightly tapering, apices delicately velutinate. Context white, 0.25-1 mm thick, of densely intertwined hyphae, separated from the pores by a delicate layer of wood coloured intertwined gelatinised hyphae; generative hyphae 6-10 µm diameter, 5-6 µm in dissepiments, lumena 2-3 µm wide, freely branched, septate, with clamp connections. Hymenial layer to 15 µm deep, a dense permanent palisade of basidia and paraphyses. Basidia subclavate or subcylindrical, 6-8 x 2.5-3 µm bearing 2-4 spores; sterigmata erect, to 3 µm long. Paraphyses subcylindrical 5-7 x 2-2.5 µm. Spores allantoid, 3-3.5 x 1-1.25 µm, walls smooth, hyaline, 0.1 µm thick.

Distribution

New Zealand, Australia, Java.

Habitat

Bark and decorticated wood of fallen branches, associated with a white rot.

Notes

Plants are commonly applanate or conchate, attached by a narrow lateral base, solitary or in small groups arising from a common base. In some collections they are attached by a narrow vertex; in one they are pezizaeform and growing upon the surface of a fallen log, attached by stem-like. bases. In microfeatures all are identical. The Victorian collection has pores slightly larger (5-6 per mm), but agrees in other features. A conspicuous cortex is present, formed from a palisade of erect hyphae which, because of unequal length, give to the surface a peculiar dull appearance although it is glabrous. Plants are hard and horny when dry, owing to the presence of mucilage encrusting walls of the context hyphae, dissepiments and hymenial layer, and of masses of mucilage lying between them. P. imporcatus is identical with some of the collections from New Zealand, even to the allantoid spores. They are not globose, as was claimed by Lloyd, who confused mould spores with those of the species.
