Shape in side view of the basidiospore.　Q (quotient) = ratio of length/width of a basidiospore.

Globose(spherical): the perfectly round spore, Q = 1.0-1.05
Subglobose: nearly round, Q = 1.05-1.15,
Broadly ellipsoid (short ellipsoid):, the shape between subglobose and ellipsoid, Q = 1.15-1.30
Ellipsoid: the simplest equilateral spore in which the ends are rounded and the sides are curved Q = 1.30-1.60
Ovoid: shaped like an egg
Elongate (= oblong): the side are almost parallel, the ends squarish,
Cylindric: the sides are more or less parallel
