Hygrocybe coccinea

Hygrocybe coccinea, sometimes called the scarlet hood, scarlet waxcap or righteous red waxy cap, is a colourful member of the mushroom "genus" "Hygrocybe". These waxcaps are found across the Northern Hemisphere from China and Japan to Europe and North America. The small bright red mushroom is a familiar sight in unimproved grasslands in Europe in late summer and autumn, and woodlands in North America in winter.
Taxonomy.
The scarlet hood was first described as "Agaricus coccineus" by German mycologist Jacob Christian Schäffer in 1774, before being transferred to the genus "Hygrophorus" by Elias Magnus Fries in 1838, and finally "Hygrocybe" by Paul Kummer in 1871. The specific epithet "coccinea" is Latin for "scarlet".
Description.
A small waxcap with an initially bell-shaped, and later flattening, cap 2–5 cm (¾–2 in) across, scarlet in colour and slimy in texture. The adnate gills are thick and widely spaced, yellow red in colour. The spore print is white. The ringless stipe is up 2–5 cm (¾-2 in) high and 0.3–1 cm (⅛-⅓ in) wide, red with a yellowish base. The flesh is yellowish-red and the smell and taste faint. The oval spores measure 7–9.5 x 4–5 μm.
Distribution and habitat.
"Hygrocybe coccinea" has a wide distribution in unimproved grasslands across Europe from August to October. In Britain, like all Hygrocybes, it has its best seasons in frost-free late autumn months, and in western North America it may be found under redwoods or in mixed woodland in winter. It has been recorded growing under "Rhododendron" and oak ("Quercus") in Sagarmatha National Park in Nepal, and also occurs in India, China and Japan.
Specimens initially identified as "H. coccinea" in Australia have been reclassified as "H. miniata" or "H. kandora".
Edibility.
The scarlet hood is edible, but of fairly little interest. It should not be confused with the inedible "H. punicea".
