From Wikipedia, the free encyclopedia
Pirum gemmata is a unicellular eukaryote that belongs to the Ichthyosporea clade, a group of protists closely related to animals. P. gemmata was isolated from the gut contents of a marine invertebrate, specifically the detritivorous peanut worm Phascolosoma agassizii.[1]

Pirum gemmata’s growth under culture conditions, is through the development of a mature syncytial stage that undergoes sporogenesis and eventually releases endospores through one or more openings in the parent cell wall. Mature cells are multinucleated, with a cell wall, and can measure up to 200 μm.[1] Endospores are amoeboid and some have pseudopod-like cell extensions.
Taxonomy
Pirum gemmata is a member of the Ichthyosporea clade, which is the earliest branching holozoan lineage.[2][3]
