Status
Most often does not appear until after the first hard frost in fall. Many mushroomers consider its appearance a signal the end of the season is in sight (J. Solem, pers. comm.).
Description
Cap: Highly variable color from yellowish-green or dark olive to brown usually with purplish tints; kidney to fan-shaped; slimy when wet; margin incurved; flesh white/thick. Gills: Bright ochre to whitish; attached to decurrent; close. Stalk: Lateral attachment; stalk stubby if present; whitish/yellowish/brownish; hairy, especially at attachment poin (J. Solem, pers. comm.).
Where To Find
Groups, overlapping clusters on dead hardwood stumps, logs, and sticks, occasionally on conifer (J. Solem, pers. comm.).

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
[edit]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
[edit]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
[edit]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]
