Late Oyster is a common, widespread, small to medium-sized, fleshy, shelf-like fungus. It is saprobic on decaying stumps and logs. It is found singly or in overlapping groups on the trunk or a large branch of a dead and decaying tree. It usually occurs on a hardwood, especially black cherry, but occasionally also on a conifer. It appears in the late fall with the onset of cold weather.

There is often no stalk. If there is a stalk it is short, 3 16 to long, thick, and laterally attached. It is yellow, brownish-white, or the same color as the cap, and is covered with velvety hairs.

The cap is kidney-shaped or semi-circular and 13 16 to 4 in diameter. The color is variable, often on the same cap. When young it is downy and often flushed with violet. As it ages it becomes hairless and olive-green to yellowish-green. Eventually it turns yellowish-olive or light brown. When wet it is somewhat slimy or sticky to the touch (viscid). The margin is rolled inward and often lobed, indented, or wavy. As it ages the margin flattens out. The flesh is thick, white, and firm, and there is a gelatinous layer just below the skin (cuticle) of the cap. It is edible but has a mediocre taste and becomes bitter as it ages.

There is no universal veil.

The gills are narrow, close together and run down the stalk if there is one (decurrent) or broadly attached (adnate). They are bright orangish-yellow, yellowish-orange with a brown tinge, pale orange, or pale yellow at first, fading with age.

The spore print is pale yellow.

Late Oyster was formerly placed in the family Tricholomataceae and known as Sarcomyxa serotina. Tricholomataceae was a “wastebasket taxon” containing all mushrooms in the order Agaricales with white, yellow, or pink spores that have not already been classified into another family. Following a large-scale phylogenetic study of Agaricales (Moncalvo, Vilgalys, Redhead, et al., 2002), seven families were segregated from Tricholomataceae. Late Oyster Mushroom was transferred to the new family Mycenaceae with the new name Panellus serotinus. In 2019 it was transferred again, this time to the new family Sarcomyxaceae, and the old name Sarcomyxa serotina was restored. The last move was not universally accepted. Species Fungorum and GBIF use the name Sarcomyxa serotina, while MycoBank and NatureServe use the name Panellus serotinus.

Vzácná jedlá houba nižší kvality vynikající však na čínu. Roste na živých i odumřelých listnatých stromech.
