Many bolete species have a cracked surface to the cap but with some it is an identifying feature. The red-cracking bolete (Xerocomus chrysenteron) has a reddish cap that readily cracks to show the yellow flesh of the pores underneath. This is a common fungus not only found in woods but also in parks and pastures, especially where beech or larch are nearby. Generally a solitary species, although occasionally found in small groups, this can be found from late summer through to early winter.
It is edible, especially if you like eating sponge!
