  Gills close, adnate to adnexed, white becoming pale brown, finely serrate, edges with droplets of liquid when young.

• Stipe

  Stipe 4-7 cm tall, 0.7-14 cm thick, equal to enlarged at the base, pallid to concolorous with cap, apex pruinose, i.e. covered with fine powdery granules; veil absent; solid; rhizomorphs usually seen at base.
