Ecology and distribution

Pycnoporellus lustrous lives on dead wood, causing brown rot. Most often it can be seen on a spruce tree, on which the bark is partially preserved. It is rarely found on pine, as well as on alder, birch, beech, linden and aspen. At the same time, he almost always settles on a valezh, on which the bordered tinder fungus has already 'worked'.

This species is confined to old forests (at least to those in which sanitary felling is rarely carried out, and there is a suitable quality deadwood). In principle, it can be found in the city park (again, there would be a suitable deadwood). The species is common in the northern temperate zone, but is rare. The period of active growth is from spring to autumn.

Description

Fruiting bodies are annual, more often they have the form of tiled sedentary semicircular or fan-shaped caps, less often prostrate-bent forms are found. The upper surface is painted in more or less bright orange or orange-brown shades, naked, velvety or slightly pubescent (bristly in old fruiting bodies), often with pronounced concentric zones.

The hymenophore in young fruiting bodies is creamy.

Older ones have pale orange, with angular thin-walled pores, 1-3 pores per mm, tubule length up to 6 mm. With age, the walls of the tubules break, and the hymenophore turns into irpexoid, consisting of flat teeth protruding from under the edge of the cap.

The pulp is up to 5 mm thick, light orange, fresh with the consistency of a soft cork, sometimes two-layer (then the lower layer is dense, and the upper fibrous), when dry it becomes light and brittle, when in contact with KOH, it first turns red, then turns black. Smell and taste are not pronounced.

Spore powder is white. Spores are smooth, from cylindrical to ellipsoidal, non-amyloid, do not blush in KOH, 6-9×2.5-4 microns. Cystyds are irregularly cylindrical, do not turn red in KOH, 45-60 x 4-6 microns. Hyphae are mostly thick-walled, weakly branching, 2-9 µm thick; in KOH they remain colorless or are colored reddish or yellowish.

Similar species

It differs from Pycnoporellus alboluteus in that it forms well-shaped caps, has a denser consistency, when in contact with KOH, it first turns red and then blackens (but does not become cherry). At the microscopic level, there are also differences: the spores and cystids are smaller, and the hyphae are not stained with KOH in a bright red color.
