acrosporen.

Brit.

/ˈakrə(ʊ)spɔː/, U.S.

/ˈækrəˌspɔr/

Origin: Formed within English, by compounding; probably modelled on a French lexical item. Etymons: acro- comb. form, spore n.

Etymology: < acro- comb. form + spore n., probably after French acrospore (1822). Compare German Akrospore (1855 or earlier). Compare acrosporous adj.

Chiefly Mycology.

Originally: †a stalked antheridium of a moss, liverwort, or other cryptogam (obsolete. rare). In later use: a spore produced at the apex of a hypha or other cellular filament forming the structural element of a fungus; a basidiospore.
