light velum zone, 1-2mm wide. G i Il s as in the preceding species
bu t at first more rose-coloured ("Light Congo Pink"). S t e m often
short, 6-8 cm X 20-30 mm, cylindrical, solid, sometimes hollow,
whitish, turning tawny when touched, gradually turning grey. Covering

P. subperonata is nearly allied to P. vaporarui, but differs from
it in the pinkish red of the flesh, the well developed cystidia on the
edge, and the less round form of the spores.
