features

Macroscopic features

The rose mushroom forms tufted or roof-tile-like fruiting bodies that grow on top of each other and protrude from the bark of the infected tree. The fan-shaped, convex or flat hats reach a size of 20-50 × 30-70 mm (width × length) and are pink, white or light gray. They have a dry surface that is velvety or tomentose to the touch and a thin, tender mushroom flesh that has a sharp, pungent odor. The hats are attached to a common, only rudimentary stem that is white in color and has a felt-like surface. The yellowish or pinkish lamellae of the rose oyster mushroom are descending, relatively wide, about 4–8 cm long and close together. Its spore print is beige. The fungus initially has a longitudinal mycelium that is covered by branched rhizomorphs and is often woolly with age and runs above ground. The mushroom threads are initially white, but take on a pink hue.

Microscopic features

The mushroom spores of the rose oyster mushroom are smooth, cylindrical and measure 6.0–9.0 × 1.5–3.0  µm . His trama is dimitic , he has cheilocystids , but not pleurocystids . The hyphae of the fungus have buckles .

ecology

The natural substrate of the rose oyster mushroom is mainly hardwoods such as palm trees , rubber trees and bamboo in the tropics and subtropics , where it is widespread. It breaks down the lignin content of the wood and thus causes white rot . He is dependent on relatively high temperatures of 20–30 ° C, as well as a relative moisture content of the substrate of 95–100%.

distribution

The rose oyster occurs in the tropics and subtropics of America and Asia. Its distribution area includes South and Latin America, Southeast Asia, Hawaii, Japan and the Antilles.
