Mycena haematopus Bleeding Mycena
This is probably the most common of the Mycena species in Eastern Canada. It fruits in clusters on well rotted logs and is often found during wet periods throughout the summer and fall. It is recognized by its distinctive colour, and the fact that the stalk 'bleeds' red juice when cut or broken. The margins of the cap frequently have an attractive, toothed fringe hanging below the edge. During extended wet periods, it is often found being attacked by Spinellus , a parasitic pin mould related to Mucor.
Caps are 1-3 cm, bell-shaped, vinaceous red, smooth, striate, and with a toothed or scalloped margin. Gills are attached, whitish, and stain reddish. Stalks are up to 8 cm tall, slender, fragile, smooth with hairy base, and coloured as the cap, exuding reddish juice. Spore prints are white. Widespread and common, it fruits in dense clusters on rotten wood.
