persed population of spore-producing cells
called basidia emerge. The basidia arise from
a genetically rich, dense surface layer on the gill
called the hymenium. The gill trama is nestled

between the two hymenial layers and is composed of larger interwoven cells, which act as
channels for feeding the hymenial layers with
nutrients. (See Figure 53). When the mushrooms are young, few basidia have matured to
the stage of spore release. As the mushrooms
emerge, increasingly more and more basidia
mature. The basidia are club-shaped, typically
with four"arms" forming at their apices.These
arms, the sterigmata, project upwards, elongating. (See Figures 47 and 48). In time, each tip
swells to form small a globular cavity which
eventually becomes a spore. (Figure 49).
Initially, the young basidia contain two hap-

bid, sexually paired nuclei. They fuse, in a
