Little Puffballs

After a long Aug-Sept draught, we got soaking rain last week, and as a result a few puffballs (Lycoperdon pyriforme) appeared on a rotting log laying just to the east of the Observatory. These are edible as long as the interior flesh is white. They turn greenish-yellow to dark olive-brown with age, then puff out their olive green spores once they dry out.

Here is a video of pyriforme in February which show how they spread their olive colored spores.
