Beech Woodwart Fungus

From a early April this year: beech woodwart fungus, Hypoxylon fragiforme. 

I am not sure what the small red particles are: they could be the spores of the fungus, or they might just be something else that happens to be living on the fungus.  [Note added 2012-02-19: they could be Nectria episphaeria, see here.]

White Cup Fungus

An tiny white cup fungus, possibly Dasyscyphella nivea, but there is a warning here, in the Wild About Britain fungi forum, that microscopic examination is really needed to identify this type of fungus to the species.  Still, it is rather pretty.

Waxcap Mushroom

A waxcap mushroom, probably Hygrocybe conica.

Puffball Fungus

From a few years back: puffball fungus Morganella pyriformis (= Lycoperdon pyriforme).  This is the same species as the decayed specimens shown here.

Update on Sun 2010-12-12 by Tristram Brelstaff

Apparently the preferred name is again Lycoperdon pyriforme.  See here.

White and Grey (and Black) Fungus

Fungus Kretzschmaria deusta (= Ustulina deusta) growing on a decaying log.  This fungus can dangerously weaken tree trunks, causing them to break.  The white and grey growths are the immature fruiting bodies which appear in the spring.  As they mature, they harden and turn black, as shown in the following photo:
