Oxyporus latemarginatus: the frothy porecrust fungus

Some fungi form lovely toadstools, others form amazing brackets, but some are just crusty and boring. Frothy porecrust (Oxyporus latemarginatus} is, as its name perhaps implies, crusty and boring! It is not much to look at forming large patches of grey, cushion-like lumps on the bark of rotting timber in dead oak and beech trees, often when they have fallen to the ground.

The crust is still the fruiting body of the fungus, of course, and the substance ouses from the tree and is soft or frothy at first but after the spores are spent they become hardened and stay on the trunk for some considerable time.

An autumn and winter species it is considered uncommon outside of the south-east of England but there is a suspicion that it is spreading and I have now seen on dead beech wood in more than one location in Dorset so I expect it is now quite widesppread here too.

Is it edible? Well, what do you think? I am not going to try it!
