Another Tachinid Fly

From back in September: a Siphona sp (Diptera: Tachinidae).  Its feeding siphon is folded back under its chin.

Tachinid Fly

From back in August: a Nowickia ferox (Diptera: Tachinidae).  It seems that the yellow palps distinguish N. ferox from the other Nowickia species (but, as we only get ferox in the UK, this fact is not of much practical use here).

Rust Fungus

From back in mid-summer: a plant gall on the underside of a nettle leaf (Urtica dioica), probably caused by the fungus Puccinia urticata.

Bracket Fungus

Brackets of Bjerkandera adusta growing on the end of a horse chestnut log (Aesculus hippocastanum).

The pore surface is grey and there are about 7 pores per mm.  This agrees with the 6-7 per m given here.  The similar Bjekandera fumosa has a white spore surface and only 2-5 pores per mm (see here)

The spores are about 4 x 2.5um (the field of view is about 86um wide).  This agrees with the 4.5–5.5 x 2.5–3um given here.

And the hyphae have clamp connections:
