Bluebottle Fly

From late summer a couple of years ago: a female bluebottle fly, probably Calliphora vicina (Diptera: Calliphoridae).  In C. vicina the lower part of the face is reddish, and the spiracle just behind the eyes (on each side of the thorax) is orange.  In C. vomitoria, which is also common, the lower park of the face is whiter, the spiracle just behind the eyes darker, and the 'chin' sports a bright orange 'beard'.

Coral Spot Fungus

A coral spot fungus, the asexual stage of a Nectria sp, possibly Nectria cinnabarina.

The sexual stage consists of small red spheres, like this (though this could be a different species of Nectria):

Remains of a Brain Fungus

What I think is remains of the crystal brain fungus Myxarium nucleatum (= Exidia nucleata) on a fallen twig. 

The white lumps are the calcium oxalate inclusions that are often visible in younger specimens (see here for example) and the brown film is the remains of the whiteish translucent fruiting bodies.  To quote from the Wikipedia page: "With age the fruit bodies may become brownish and eventually dry to a thin, varnish-like film".
