Fungus

Dead moll's fingers fungus, Xylaria longipes.  The one on the right has been nibbled, probably by a mouse or a squirrel (would a slug climb all the way to the top before starting to nibble?).

I prepared a microscope slide of the spores using the method given here and this is the result (at x600):

These spores are roughly 1.5 times the length of the spores of Peniophora quercina shown here.  This, and the shape shown above, is consistent with the description given for X .longipes which includes 'Spores 13-15 x 5-7 um; smooth; fusiform' (fusiform = spindle-shaped, ie: pointed at both ends).

At first I assumed this fungus to be Xylaria polymorpha but that has 20-31 x 5-10um spores, which would be 2 to 3 times as long as those of P. quercina.  This is clearly not the case with the spores in the above image.

Moth

From back in August: tortrix moth Pandemis corylana (Lepidoptera: Tortricidae).  A bit over-exposed.

Bracket Fungus

What it think is blushing bracket fungus, Daedaleopsis confragosa, growing on a dead branch of a willow tree (Salix sp). 

The underside looks like this:

And the spores (prepared by the method given here) look like this at x600:

These spores are smaller and thinner than those of Peniophora quercina, which is roughly consistent with the 'cylindric 8–11 x 2–3um' given here.

The first photo and the specimen were take in Whiteknights Park, Reading, UK, on 2012-12-15.

Venus and the Moon

From last Tuesday morning: planet Venus and the crescent Moon in the pre-dawn sky.  Mercury should have been visible a few degrees to the lower left of Venus, but I did not notice it at the time and so did not include it in the image.

Yellow Fungus on Grass

From back in summer-time: a yellow crust on a grass stem.  Initially I assumed this was the eggs of some insect but now I think it is a fungus of genus Epichloe, possibly Epichloe typhina.
