1855 J. B. Sanderson in Todd's Cycl. Anat. & Physiol. V. 221/1 The term Polyspore is usually applied..[to] a gelatinous..pericarp or conceptacle.

1867 J. Hogg Microscope (ed. 6) ii. i. 272 The first form to which the term polyspore has been applied, is that of a gelatinous or membranous pericarp or conceptacle, in which an indefinite number of sporidia are contained.

2. A group of more than four spores, esp. in certain red algae.
