Appearance

The cap of "Mycena alcalina" ranges from conical to bell shaped and is generally 1–4 cm in diameter. The cap is supported by a thin, hollow stem growing anywhere from 20-65mm long. The cap appears black at first, but fades to a grey-brown colour around the edges, with the stem generally being the same colour as the cap. The flesh of "Mycena alcalina" ranges from white to translucent and is fragile and thin. This species of mushroom is edible, but it has a mild acrid taste and distinct bleach-like odour, making it unpleasant to eat.
YAM! When crushed these fellows emitted a bleach like odour. Although they could in actual fact be M. leptocephala. As David Arora says in his book “Mushrooms Demystified”, “YAM, yet another mycena!”. About the edibility he says, “Who knows? Who cares? I don’t. Do you?” This group had colonized the top surface of a moss covered log. Canada,Fall,Geotagged,Mycena alcalina,Mycena leptocephala,Nitrous bonnet,Stump fairy helmet mushroom

Habitat

"Mycena alcalina" is saprotrophic, meaning it derives nutrients from the breakdown of organic materials through use of extracellular enzymes. This particular species is found most often growing on the wood of coniferous trees. It can typically be found growing during the early summer and fall.
