This species, which the author has known since 1939, only differs
from P. arvensis by its occurrence in meadows near the shore, its
small scales placed in a circle on the ring, its short, stocky stem
with a fairly firm and narrow pith, and more especially by the f act
that the pellicle is only pure white when quite young, but already before
the bursting of the veil becomes distinctly ochre yellow and most
frequently cracks radially, almost like an Inocybe (hence the name
[issurtiia), with narrow, lighter-coloured fissures between the yellow
patches of the pellicle. The tendency to form bottle-shaped marginal
cystidia seems to be the only demonstrable microscopic difference
from P . aroensis, to which it may perhaps approximate by inter-
