Hapalopilus rutilans

Ciri dan struktur

The cap is fan-shaped to semicircular and convex, reaching a diameter of 2.5 – 12 cm. It lacks a stalk, and is instead attached broadly to the substrate. The fruit bodies are initially soft and spongy, but become hard and brittle once they have lost their moisture. The cap surface is covered with matted hairs, has shallow concentric furrows, and a dull brownish-orange color. The flesh is up to 3 cm thick at the thickest part, and is a pale cinnamon color. The pore surface is yellowish to brownish, and the pores are angular, numbering about 2–4 per millimeter. In young fruit bodies, the pore surface bruises reddish brown. The mushroom's odor and taste ranges from sweetish to indistinct. Fruit bodies produce a white spore print. Spores are elliptical to cylindrical, smooth, hyaline (translucent), and measure 3.5–5 by 2–3 μm. The basidia (spore-bearing cells) are club shaped and four-spored, with dimensions of 18–22 by 5–5.6 μm. H. rutilans has a monomitic hyphal system, containing only generative hyphae with clamp connections. In the flesh, these hyphae are thick-walled and highly branched, measuring up to 10 μm in diameter; hyphae comprising the pores and the subhymenium are thinner (up to 6 μm wide) and less branched. A chemical test can be used to help identify H. rutilans: all parts of the fruit body will instantly stain bright violet if a drop of an alkaline solution is applied. Dilute (3–10%) potassium hydroxide (KOH), is often used for this purpose.

Habitat dan peran ekologis

A saprobic species, Hapalopilus rutilans causes a white rot in its host. Fruit bodies of the fungus grow singly, in groups, or in fused and overlapping clusters on the wood of dead and decaying deciduous trees. Preferred hosts include Quercus (oak), Fagus (beech), and Betula (birch), although on rare occasions it has been recorded on conifer wood as well. In central Europe, its preferred host is oak, while in northern Europe it is found most commonly on Corylus and Sorbus. Fruiting typically occurs from early summer to autumn, but the tough fruit bodies are persistent and may be encountered out of the usual growing season. Hapalopilus rutilans has a mostly circumboreal distribution in the north temperate zone, and has been found in North Africa, Asia, Europe, and North America. Outside of this region, it has been recorded from Australia, and Oceania. In North America, where it can be found as far north as the Northwest Territories in Canada, it is more common in the eastern and southwestern part of the continent. In Europe, its northern distribution extends to Porsanger in Norway. Reported for the first time from India in 2011, it was found in forests depots of Chhattisgarh, growing on the stored logs of several native trees: Anogeissus latifolia, Chloroxylon swietenia, Desmodium oojeinense, Shorea robusta, and Terminalia elliptica.
