Pileus width (cm), basidiocarp width (resupinate species)

English

If the　pileus shape is orbicular (round), pileus width is a diameter of the pileus.

If the pileus shape is flabelliform, petaloid, spatulate or dimidiate pileus width is the longest part from the point attached to the substrate (except the stipe) to the edge of the pileus.

If the pileus shape is semicircular, pileus width is the radius of pileus.

If the pileus shape is elongated, pileus width is the longest length from a substrate that pileus attached to the end of the pileus.

If the basidiocarp is resupinate (apileate) and is looked on a rectangle, the width is the shorter side of the basidiocarp.
