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).
