摘要

The genetics of taxonomic traits is poorly documented in the genus Agaricus. By integration with recent phylogenetic data, new hypotheses emerge concerning the white colour of the pileus and the 'phenol' odour. In numerous multispecies clades and in species, coloured and white pilei coexist, suggesting that they could derive from an ancestral polymorphism. Correlations between the white pileus and the open habitat (i.e., not under trees) suggest that the white cap could represent an advantage by providing better resistance against the sunlight and consequently against desiccation. In section Xanthodermatei, the phenol odour increases from the more basal clades to the more terminal ones. Correlatively, the main toxic phenolic compounds are p-quinol in a species of the most basal clade, and phenol in the most terminal clade. We hypothesise that phenolic secondary metabolites deriving from an initial ancestral biochemical shift, are implicated in defence mechanisms against animals and /or micro-organisms.
