Comentario: Lamellulae (short gills) are rounded truncate to attenuate. This lends some support to the idea that this species belongs in sect. Validae. The shape of the bulb (somewhat pointed on the bottom and a bit turnip-like) may be of some help. I made a mistake, Karin, in not suggesting that you post the picture you sent me with the good view of the bulb. I think that may be a clue worth having on this observation.
