Pseudoinonotus dryadeus), commonly known as oak bracket, warted oak polypore, weeping polypore or weeping conk, is an inedible species of fungus belonging to the genus Inonotus, which consists of bracket fungi with fibrous flesh.

Most often found growing at the base of oak trees, it causes white rot and decay of the trunks.

[3] Its velvety upper surface is cream to rusty brown with a yellower margin, and is pitted with tubes up to 3 cm deep which ooze an orange-brown liquid when the fruit body is young,[1][4] hence the name "weeping conk".

Inonotus dryadeus is a parasitic saprobic fungus,[1] with spores entering wounds on broadleaf trees (predominantly oak, although sometimes maple, elm and chestnut).

It has been observed in North America and temperate northern Europe, where it is described as widespread but locally common.
