This small, delicate-looking fungus was growing under deciduous trees, on a sparsely grassy verge by the track around the lake at Newmillerdam Country Park. They remind me of the little folded-paper parasols used to decorate a cocktail but this isn’t the parasol mushroom.
The caps in the background appear to be the older ones and, like the inkcap that I drew the other day, they are turning black around the gills, although I suspect that these aren’t closely related.
It might be a species of Mycena.
