Mushrooms Marcos number 14 - Commonly known as the Bleeding bonnet or by it's Binomial name Mycena sanguinolenta is a very widely distributed mushroom in the northern hemisphere. Here in the UK, this species can be found on humus and vegetable debris among grass and moss, on fallen twigs and moss-covered trunks of both deciduous trees and coniferous trees, and among fallen needles of coniferous trees; therefore, the most common habitat would be forests or woodlands. With this is mind, & more importantly because it belongs to the family Mycenaceae, the sanguinolenta is a saprotrophic, so therefore usually found in summer to Autumn however throughout the year. With it's shaped hemispherical, pointed, sulcate, and umbrella-like cap, this is a very distinctive feature when I look out for this mushroom.
