Basidiocarp is the part of mushroom that comes out from soil.

Ascogonium is a female reproductive body in some ascomycetous fungi from which asci are produced.

Ascocarp is the fruiting body (sporocarp) of an ascomycete Phylum fungus. It consists of very tightly interwoven hyphae and may contain millions of asci, each of which typically contains four to eight ascospores.

Pericarp is the part of a fruit formed from the wall of the ripened ovary.
