Gyroporus castaneus

Ciri dan struktur

PILEUS: convex to plano-convex, 3.5-5.5 cm diam., dry, finely tomentose to velutinate, cocoa brown, chestnut brown, or cinnamon brown; cuticle composed of short-celled, filamentous hyphae 8-15 µm diam., usually with conspicuous clamp connections and brown contents, terminal cells resembling dermatocystidia, often projecting at right angles to surface; margin entire. HYMENOPHORE: tubes to 7 mm long, excavated around apex of stipe, white when young, pallid yellow at maturity; pores concolorous with tubes, subregular, 0.5-1 mm diam. STIPE: 4-5 cm long, tapering apically, occasionally subcylindrical, 1-2 cm diam., solid at first, becoming stuffed, finally hollow, dry, tomentose to velutinate, concolorous with pileus or paler apically; flesh white to sordid white; annulus absent. SPORES: spore print not obtained, reported to be between Amber Yellow and Citron Yellow; spores pallid stramineous, short-elliptical, often ovate and flattened on one side, 7.4-11.7-(13) X 5.2-6.5-(7.2) µm., smooth. HYMENIUM: basidia hyaline, clavate, 27-35 X 9-12 µm, 4-spored; cystidia sparse on tube walls, crowded at tube mouths, hyaline, thin-walled, subulate with rounded apices to ventricose-rostrate, 35-52 X 5.2-9.8 µm.. HYMENOPHORAL TRAMA: bilateral, of the Boletus subtype; clamp connections present. CONTEXT OF PILEUS: white to sordid white, unchanging on exposure to air. TASTE: mild. SMELL: not distinctive. CHEMICAL REACTIONS: KOH and NH4OH on pileus and context of pileus—no reaction.

Habitat dan peran ekologis

Gyroporus castaneus is widely distributed throughout temperate regions of the northern hemisphere, where it occurs in association with both coniferous and broad leaved trees. The fact that both the above collections were found in relatively undisturbed native forest suggests that it is indigenous to New Zealand. Singer (1945b) noted an unconfirmed report of its occurrence in Australia, but did not state whether it was indigenous or introduced. G. castaneus is reported to be an edible fungus by European mycologists. The species is readily recognisable by the chestnut brown fruit bodies, hollow stipe, pallid stramineous spores, and presence of clamp connections. It has not previously been recorded from New Zealand.
