Claim: The Basidiomycota has gills on hymenium (the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores), which is adnexed.
Evidence: The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In agarics, the hymenium is on the vertical faces of the gills.
