Comments: It is interesting to observe how the pilei are changing color with time. Young pilei are almost black tinged deep blue or violet; the gills are initially whitish or lightly bluish. These colors are then gradually changing to more pinkish and finally to brownish colors. One can find quite differently looking pilei next to each other. The gills have characteristic and usually distinctive blue-black edge.

The mushrooms were photographed on two places near each other on the same pasture. They were growing solitary and in scattered groups of several fruit bodies. There were about 20 of them all together. Pilei diameter from 20 to 35(48) mm, stipe from 6 to 11 cm long and from 2 to 3.5 mm in diameter; flesh brittle; stipe fibrous, hollow; SP abundant, pinkish-ochre, oac651.
