During a walk at Fitzwilliam Country Park, I came across some common puffballs (Lycoperdon perlatum). They were just pushing up through the moss and I thought they looked very striking.
There were quite a few Russulas growing beneath silver birches and young oaks. I identified one of these as green Russula (Russula aeruginea).
At Ackworth, I found a clump of fungi which seemed to be a species of Agaricus. For these, I needed the help of the experts at the British Mycological Society. Agaricus bohusii was suggested initially but Geoffrey Kibby, who has published a number of authoritative guides to fungi, suggested that this fungus was a particularly scaly example of Agaricus subperonatus.
Agaricus subperonatus isn’t a common species, so this was an interesting find.
