Historical Examples of antheridium
The index reference for "Antheridium" should probably be 159, rather than 150, but was not changed.
A fruiting portion, magnified, showing the structure; a sporocarp, and an antheridium.
The antheridium consists at first of a basal cell and a terminal one.
These cells, especially the outer ones, develop a great amount of a red pigment, giving the antheridium its characteristic color.

Word Origin for antheridium
- An organ in certain organisms that produces male gametes. Antheridia are found in many groups of organisms, including the bryophytes, ferns, ascomycete fungi, and some algae. Most gymnosperms and all angiosperms, however, have lost the antheridium, and its role is filled by the pollen grain. Compare archegonium.
