Tachinid Fly

From my walk on Sunday: a small grey fly, probably a Siphona sp (Diptera: Tachinidae), on ragwort.  Flies in this genus feed through a thin foldable siphon (proboscis)..  In the above photo the siphon is folded and sticks out forwards from below the head; in the following photo it is partly unfolded.

Fungus

What I think is dead man's fingers fungus, Xylaria polymorpha, growing on a decaying log.

I now think this is Xylaria longipes.  This species tends to be thinner than Xylaria polymorpha and has a distinct narrow stalk.

Red Slime Mould

From a few days ago: fresh sporangia of a red slime mould.  It was on the underside of a log.  I have no idea of the species nor even the genus [Note added 2013-12-26: probably an Arcyria sp.] but I will keep an eye on it over the next few days to see how it develops and that might give some clues.

The slime trail on the right-hand side is probably just a slug trail and nothing to do with the slime mould itself.
