Fuscoporia gilva, commonly known as the oak conk,[1] is a species of fungal plant pathogen which infects several hosts.[2]
Description
The fruit bodies typically grow in rows of horizontal platforms, which grow over several years and sometimes "smear" onto the wood. The caps are usually semicircular with lumpy margins, 2–10 centimetres (3⁄4–3+7⁄8 inches) wide, with zonate colouration ranging from dark brown to light reddish-brown or yellowish at the margin, which is up to 1 cm thick and velvety. There are 5–8 pores per square millimetre. The flesh is tough and corky. The spore print is yellow.[3]

Mensularia radiata is usually found on non-oak hardwoods; fresh specimens often exhibit white-tipped pores near the margin.[3]
