Ciri dan struktur
The fruit bodies of Mycena haematopus are the reproductive structures produced by cellular threads or hyphae which grow in rotting wood. The shape of the cap of the fruit body will vary depending on its maturity. Young caps, or "buttons", are ovoid (egg-shaped) to conical; later they are campanulate (bell-shaped), and as the fruit body matures, the margins (cap edge) lift upward so that the cap becomes somewhat flat with an umbo (a central nipple-shaped bump). The fully grown cap can reach up to 4 cm in diameter. The surface of the cap initially appears dry and covered with what appears to be a very fine whitish powder, but it soon becomes polished and moist. Mature caps appear somewhat translucent, and develop radial grooves mirroring the position of the gills underneath. The color of the cap is reddish- or pinkish-brown, often tinged with violet, and paler towards the edge. The margin is wavy like the edge of a scallop and may appear ragged because of lingering remnants of the partial veil. The gills have an adnate attachment to the stem, meaning they are more or less directly attached to it. They are initially whitish or "grayish vinaceous" in color, and can develop reddish-brown stains. Between 20 and 30 gills reach from the cap edge to the stem, resulting in a gill spacing that is described as "close to subdistant"—gaps are visible between adjacent gills. There are additional gills, called lamellulae, that do not extend directly from the margin to the stem; these are arranged in two or three series (tiers) of equal length. The stem is 3-9 cm tall and 0.1–0.2 cm thick, hollow and brittle, and a dark reddish-brown color.
Habitat dan peran ekologis
In North America, M. haematopus is distributed from Alaska southward. According to Mycena specialist Alexander H. Smith, it is "the commonest and the most easily recognized one in the genus". The species is common in Europe and has also been collected from Japan, and Mérida, Venezuela (as the variety M. haematopus var. marginata). In the Netherlands, M. haematopus is one of many mushrooms that can regularly be found fruiting on ancient timber wharves. The fruit bodies can be found year-round in mild weather. The mushroom obtains nutrients from decomposing organic matter (saprobic) and the fruit bodies can typically be found growing on stumps and well-decayed logs, usually in groups that are joined together by a common base. The decomposition of woody debris on the forest floor is the result of the combined activity of a community of fungal species. In the sequential succession of mushrooms species, M. haematopus is a "late colonizer" fungus: its fruit bodies appear after the wood has first been decayed by white rot species. The initial stage of wood decay by white rot fungi involves the breakdown of "acid-unhydrolyzable residue" and holocellulose (a mixture of cellulose and hemicellulose).
