Redlead roundhead – try saying that name several times at speed – a real tongue-twister! Its scientific name is also a bit of a mouthful: Leratiomyces ceres, the ceres epithet a reference to the red of its cap, though I’ve found they’re more of a rusty red than cerise.

This fungus is an ‘alien from Australia’ that favours wood chip, particularly on sandy soil, and it owes its spreading distribution to the way many park departments cover areas of ‘gardens’ with chippings of trees from wide and varied sources. I found this particular specimen on the Cardiff Bay Barrage, growing on bits of wood washed down the Rivers Ely and Taff during flooding events.
