Lots of fungi have fruiting bodies (the bits which we can normally see) which only last briefly at the best of times. Most of these are sensitive to cold, and aren’t seen after frosty weather.
Over then next few days, I’ll be posting pictures of fungi I’ve noticed this month, which have survived several freezings and re-thawings. Here a clump of velvet shanks on a tree stump. The stump was on raised ground, right at my eye level.
