Common Name: Split Gill
This small, ashy-grey bracket looks like a polypore but the lower, hymenial surface consists of gills, the latter unusual in that they are split longitudinally. The genus name Schizophyllum, literally means "split leaves" referring to this character. Fruiting bodies are persistent, shriveling in dry weather, but reviving after rains.

(common names include yellow brain, golden jelly fungus, yellow trembler, and witches' butter[2]) is a common jelly fungus in the Tremellaceae family of the Agaricomycotina. It is most frequently found on dead but attached and on recently fallen branches, especially of angiosperms, as a parasite of wood decay fungi in the genus Peniophora.[3] The gelatinous, orange-yellow fruit body of the fungus, which can grow up to 7.5 cm (3.0 in) diameter, has a convoluted or lobed surface that is greasy or slimy when damp. It grows in crevices in bark, appearing during rainy weather. Within a few days after rain it dries into a thin film or shriveled mass capable of reviving after subsequent rain.
