Flesh dirty buff or straw-coloured in cap, lemon-yellow in stem apex, vinaceous or blood-red below and brownish at the base, bluing slowly over the tubes; taste and smell not distinct. Tubes lemon-yellow, flushed greenish when older. Pores large, angular; colouring similar to the tubes, bruising blue. Spores 11–14×4.5–5.5¼, subfusiform. Spore print olivaceous walnut-brown.
