Gleba cellular, cells about 1-2 mm diam., not distinctly radially arranged; brownish, without well differentiated tramal plates, not gelatinised. Stipe 6-20 x 3-4 mm, cylindrical or fusoid, attenuated towards the apex (columella), normally transcurrent and extending to the cortex of the cuticle but rarely terminating abruptly in the gleba; yellow, ornamented with distinct, adpressed, orange or reddish coloured zones forming one or more girdles of the veil; when wet slightly viscid, becoming dry with age. fistulose.
