Introduction:
This is a small specie, very variable about colour. This variability confused several mycologists in the past and sometimes they have believed to discover a new specie; for this reason, as frequently happens in the case of a variable specie, Mycena amicta has received many names, as you can see below.
Systematics:
Kingdom: Fungi
Division: Basidiomycota
Class: Basidiomycetes
Subclass: Agaricomycetidae
Order: Agaricales
Family: Tricholomataceae
Genus: Mycena
Species: Mycena amicta (Fries) Quélet
Nomenclatural informations:
Mycena amicta was published by Elias Magnus Fries as Agaricus amictus on Systema mycologicum vol. 1: pag. 141 in 1821. It was recombined by Lucien Quélet in the Mycena genus with a publication on Mém. Soc. Émul. Montbéliard, Sér. 2-5 pag. 243 in 1872.

Macroscopic features:
Pileus broad-obtusely conic to conic-campanulate, usually with obtuse umbo. Surface faintly pruinose at first, completely covered by a thin separable and lubricous pellicle. Colour very variable: grey, yellow-grey, yellow-pink, blue, dark-blue, green-blue, etcetera. Lamellae close, narrow, adnate to nearly free, whitish, then pale avellaneous. Stipe pallid to sordid brownish gray, hoary from a dense pruinose-pubescent covering, with lower part yellow-blue to green, with or without briar. Odour and taste mild.
Microscopic features:
Spores 7-9 X 4-5 micron, narrowly ellipsoid, smooth, amyloid. Pleurocystidia smooth and not differentiated, cheilocystidia smooth and abundant, hyaline, narrowly fusoid. Clamps present in all structures.
Habitat and vegetative life:
Scattered to densely gregarious on conifer needles and debris or on rotting conifer wood. It was found under Pinus pinea, Pinus pinaster, Picea abies, Abies alba, Fagus sylvatica and Alnus viridis in spring-summer. It is common in Europe, in the United States and in Canada.
Possible confusions:
A very closed specie is Mycena subcaerulea (Peck) Saccardo which has globular to sub-globular spores, not ellipsoid. Others similar species are Mycena cyanorrhiza Quélet, Mycena pachyderma Kühner and Mycena pseudocyanorrhiza Robich which are different colour, always without blue tonality, and both cheilocystidia and pleurocystidia with several extensions on the top. |
