Yellow-cracked bolete – one picture is of a mushroom someone had kicked over, showing than on the underside of the cap the spores are released through pores not gills in this genera. The same picture shows how the yellow pores turn blue when bruised.
The final picture in the set is of a lone individual of a different but unidentified bolete species which was growing under the same few trees outside a block of flats, the former Wolverhampton Customs and Excise Office.
