Sarcomyxa serotina is a species of fungus in the family Sarcomyxaceae. Its recommended English name in the UK is olive oysterling. ^[1] In North America it is known as late fall oyster or late oyster mushroom. ^[2]

Description

The fruit bodies predominately comprise greenish, overlapping fan- or oyster-shaped caps. The caps are up to 9 centimetres (3+1⁄2 in) wide. ^[3] The gills on the underside are closely spaced, bright orange yellow, and have an adnate to decurrent attachment to the short and stout stem. ^[3] The spores are smooth, amyloid, and measure 4–6 by 1–2  μm; they produce a cream to yellow spore print. ^[4]

Habitat

It grows on fallen hardwood and sometimes conifers in cold weather in North America, serving as an indicator that the mushroom season is nearly over. ^[2]

Uses

The species is considered to be either edible but not choice ^[2] or inedible, with a flavour ranging from mild to bitter. Research has revealed that two separate species exist, Sarcomyxa serotina and S. edulis (unknown in Europe). ^[5] The latter is cultivated for food in China and Japan. ^[6]
