2. Fruiting Bodies

Themorphological diversityof fruiting bodies
in Agaricomycetes is unparalleled in any other
clade of Fungi. Agaricomycete fruiting bodies
include complex, developmentally integrated
forms, such as stinkhorns (e.g., Clathrus

ruber, Phallales) and veiled agarics (e.g.,

Lepiota lilacina, Agaricales), as well as rela-

tively simple corticioid forms (e.g.,Trechispora

stevensonii, Trechisporales). Agaricomycete

fruiting bodies range over several orders of

magnitude in size, from tiny cyphelloid

forms, such asHenningsomyces candidus or
