Chromozero blue-plate - Chromosera cyanophylla

Description

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.

Spore powder is white. The spores are elongated, of various shapes, 7.2-8×3.6-4.4 μm, Q = 1.6 … 2.5, Qav = 2.0, Me = 7.7 × 3.9, thin-walled, smooth, hyaline in water and KOH, non-amyloid, not cyanophilic, with a pronounced apiculus.

The leg is 2-3.5 cm high, 1.5-3 mm in diameter, cylindrical, often with an expansion at the base, often curved, slimy, sticky and shiny in high humidity, sticky, dirty-gristly in dry weather. The colors of the leg are varied, with purple-brownish, yellow-purple, yellow-green, olive shades; dirty fawn in young or old mushrooms; often pronounced blue-violet at the base.

Habitat

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.

Edibility

The edibility is unknown.
