Sarcomyxa serotina

Appearance

The gills on the underside are closely spaced, bright orange yellow, and have an adnate attachment to the stipe. It produces a yellow spore print; spores are smooth, amyloid, and measure 4–6 by 1–2 µm. The caps are edible, but some people report the taste to be bitter—a factor that may depend on the host tree on which it is found.

Uses

In Japan, where it is called "Mukitake", it is considered "one of the most delicious edible mushrooms", and a system has recently been developed to cultivate the mushroom in plastic greenhouses.
