Chromozero blue-plate - Chromosera cyanophylla


Hat with a diameter of 1-3 cm; first hemispherical with a flattened or slightly depressed center, with a tucked edge, then truncated-conical with a raised or upwardly curved edge; smooth, sticky, slimy in wet weather; striatal from the edge of the cap and up to ¾ radius; in older specimens, it is possibly hygrophane. Initial color is dull yellow-orange, ocher-orange, olive green with orange tints, lemon yellow; then dull yellow-olive with green, orange and brown tints, grayish-olive by old age. There is no private veil.

The pulp is thin, the shades of the colors of the cap, the taste and smell are not expressed.

The plates are thick, sparse, descending; up to 2 groups of shortened plates are present. The color is initially fawn pink-violet, then blue-violet, and, towards old age, gray-violet.

It grows in the first half of summer (perhaps, not only, these are my personal observations, according to which it grows together with Mycena viridimarginata both in time and in the substrate), on rotten coniferous wood: spruce, fir, according to literature, less often, and pine trees.

Similar species

There are no similar species due to the very peculiar color of the fruit bodies. At first glance, some faded specimens can be mistaken for Roridomyces roridus, but at a second glance, this version is swept away immediately.


The edibility is unknown.
