Hymenomycete

Hymenomycete: formerly a taxonomic group of basidiomycetes, now understood as polyphyletic assemblage of basidiomycetes. Refers to fungi with fruit bodies whose hymenophore developes not enclosed or only so with a veil (velum, which is called a gymnocarpic or hemiangiocarpic ontogeny, respectively. Puffballs, on the other hand, have gasterocarpic development (hymenophore enclosed).
