Boletus subtomentosus, Suede Bolete.
One of our commonest Boletes, this one has a mat brown cap (like suede) which very soon cracks all over to show the yellow flesh beneath (hence the old name "Yellow-cracked Boletus") It does not get very large, cap 5-8cm across, with a short stout stipe, up to 5cm high. The pores are pale yellow, rather large and angular, especially near the stipe, where they grow down the stipe a little way. It is edible, and is found in woodlands, often in groups and sometimes in rings.
