Marginal cystidia: spear- or sword-shaped, roughened with crystals at the top and appearing as if barbed like fish-spines.
Facial cystidia: numerous and similar to marginal cystidia.
Habitat & Distribution: Common in autumn in woods; also found in pastures.
General Information: A very common fungus which is rather confusing to the beginner because of its variation in colour, brought about by the change in colour with change in content of water. However, this fungus can be easily recognised by the unusually ornamented cystidia found on the gill-faces and gill-margins. This character and the fact that the spores possess amyloid ornamentation define in part the genus Melanoleuca. In many books this common fungus is found under the genus Tricholoma; however, members of this latter genus have neither amyloid ornamented spores nor barbed cystidia.
