More Fungi on Rotting Wood

Stump Puffball Fungi - Lycoperdon pyriforme

I'm fairly certain of the identification of this fungi growing on a pile of logs in Keil's Den, as this is the only puffball that grows on rotting wood. The openings that can be seen are for spore release.

Woodwart - Hypoxylon sp.

Think this is probably beech woodwart -hypoxylon fragiforme -growing in the Serpentine Walk, although hazel and alder are also present. Lichen is also present on the log.
