I initially thought these were a type of funnel fungi, one of the several Clitocybe species perhaps but, as I’m only too well aware that I’ve forgotten most of what I ever knew – never much – about fungi identification, I consulted an expert, Emma [@Coalspoilfungi on Twitter]. Turns out I was wrong – no surprise there!
These are Brown rollrims (Paxillus involutus) and they were massive, the biggest at least 12 inches across. They were growing on a grassy verge, next to a very busy local road. Emma told me: ‘They would have been viscid when wet, but when dry, [are] the texture of silky soft pig leather. Gills, cap and stem bruise easily deep red /orange to dark brown / Blackening slowly.’ Fungi are just so fascinating!
