Found under spruce and fir, on a rotting log.
These were a little strange, the people at the SMG meeting did not know what they were, although it was good material. So I borrowed a Mycena book and put them under the scope.
They had clavate cheilocystidia, with numerous small sharp extentions, giving then a kinda flat-top buzz cut sorta look. There were also similar pleurocystidia. The spores were smooth, ellipsoid, and amyloid, apr. 6-9 um in length. The spore size was strangely variable. There were no reactions to Meltzer’s in the gill trama.
Looking at the sources, the section was fairly well determined with the cystidia shape. The green colors through it off though. There are a few species with these green colors, but all the habitats were wrong, and they were rare and in strange places. But then looking in the description for the common species in this section – M. arcangeliana, is see that is it sometimes found to be olive green in color, although it is usually off-white to gray. This fact was not in the key, so the key steered me wrong there, towards the green species.
In any case, these are the fairly common wood rotting Mycena arcangeliana, but in a strange greenish form.
