Polyporus atrostrigosus Cooke 1890

Latin

Polyporus (Hispidi) atrostrigosus, Cke.
Pileo dimidiato, carrnoso, postice effuso, olivaceo-filligineo; pilis strigosis adpressis virgato, margine acuto, contextu albo, tubulis elongatis, poris albis, minutis, rotundatis, dissepimentis tenuibus.

Notes

With somewhat the appearance of a Polystictus, but anodermeous. Pileus 1-2 inches or more diam., half an inch thick behind.

Typification

On stumps, etc. New Zealand. (Colenso 522.)

Description

Hymenophore annual, solitary, laterally attached by a broad base, hard and woody, sometimes dimidiate and imbricate. Pileus triquetous or fan-shaped, to 4 cm. x 1.5-2.5 cm. x 5-8 mm.; surface black, densely coated with coarse imbricate strigose tufts of hyphae radiately arranged, vaguely sulcate, cuticle wanting, replaced by imbricate hyphae with rounded ends and fuscous walls; margin bluntly acuminate, lacerate, inturned; hymenial surface wood colour to smoky brown, irregular, dissepiments strongly toothed. Context white or cream, 2-5 mm. thick, of parallel hyphae radiately arranged, firm and woody; generative hyphae 5-7 µ thick, wall 1 µ, sparsely branched, septate, clamp connections abundant and large. Pores irregular, angular, to 5 mm. deep, wood colour in section, waxy, 100-200 µ diameter, or 4-6 per mm.; dissepiments 50-150 µ thick, of parallel hyphae cemented together, tapering to the apex where even. Basidial type clavate, basidia clavate, 10-12 x 3-4.5 µ. Spores allantoid, 5-5.5 x 1.5-2 µ, smooth, hyaline.

Distribution

New Zealand.

Habitat

Growing solitary, sometimes imbricate, on decorticated rotting logs lying on the forest floor.

Notes

Characterized by the coarse, imbricate, strigose black hairs which clothe the surface of the pileus. The pigmented walls of these separate the species from P. setiger, which otherwise it resembles.

Lloyd (1922, p. 1147) recorded the species from Tasmania. He described the spores as being elliptical, 6 x 5 µ, so had obviously confused the species with some other, probably P. pelles Lloyd, which has the pileus covered with dark coloured erect fibrils.

Description

Hymenophore annual, solitary, hard and woody, laterally attached by a broad base, sometimes dimidiate and imbricate. Pilei triquetous or flabelliform, 2-4 cm wide, 1.5-2.5 cm radius, 5-8 mm thick; pileus surface dingy grey or black, densely clothed with coarse imbricated strigose tufts of hyphae radiately arranged, with walls fuscous and bearing granules of mucilage, obscurely sulcate; without a cortex; margin bluntly acuminate, lacerate, inturned; hymenial surface wood colour or smoky brown, irregular. Pores irregular, wood colour in section, angular, 4-6 per mm, 100-200 µm. diameter, to 5 mm deep; dissepiments 50-150 µm thick, tapering, apices strongly toothed. Context white or cream, 2-5 mm thick, firm and woody, of parallel hyphae radiately arranged and aggregated at intervals into compact bands; generative hyphae 5-7 µm diameter, 3-4 µm in dissepiments, walls 0.5-1.5 µm thick, sparsely branched, septate, with clamp connections. Hymenial layer to 18 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 10-12 x 3.5-4 µm, bearing 2-4 spores; sterigmata erect, slender, to 3 µm long. Paraphyses subclavate or subcylindrical, 6-10 x 3-3.5 µm. Spores allantoid, 4-5.5 x 1.5-2 µm, walls smooth, hyaline, 0.1 µm thick.

Distribution

New Zealand, Tasmania.

Habitat

Solitary or occasionally imbricate on bark or decorticated dead branches and trunks, associated with a brown cubical rot.

Notes

Specific features are the coarsely imbricated strigose black hairs clothing the pileus surface, small pores, and allantoid spores. The species is close to T. setiger, differing mainly in the smaller pores and different type of surface hairs. Lloyd (1922b, µm. 1147) recorded the species from Tasmania, but as he described spores as being elliptical, 6 x 5 µm, it is probable he had at hand a specimen of T. pelliculosus, which it resembles in surface features.

Description

Postia atrostrigosa (Cke) comb. nov. Basionym: Polyporus atrostrigosus Cke, Grevillea 19: 2. 1890.
Postia atrostrigosa is part of a complex of species surrounding Postia caesia (Schrad.: Fr.) Karst., given the blue colouration of the fruit bodies upon bruising or drying and the amyloid, allantoid basidiospores.
