Soliformovum expulsum is a species of protostelid amoeba, a type of slime mould.[1][2] [3] It was formally reclassified and described by Frederick W. Spiegel in 1994,[4] based on earlier descriptions by Lindsay Shepherd Olive and Carmen Stoianovitch.
Taxonomy and etymology
[edit]The species was originally described as Protostelium expulsum by L.S. Olive and C. Stoianovitch in 1981.[3][5] It was later moved to the genus Soliformovum in a 1994 revision by Frederick W. Spiegel.[4] The genus name Soliformovum refers to the "sun-shaped" appearance of certain life stages, while the specific epithet expulsum refers to the forceful discharge of its spores.
Description
[edit]Soliformovum expulsum is characterized by its reproductive structures known as sporocarps (sometimes called sorocarps to distinguish them from spore-producing structures in fungi or ferns).[3]
Sporocarp structure: Each sporocarp consists of a single spore perched atop a slender, non-cellular stalk. Spore Discharge: Unlike many other protostelids that rely on passive dispersal, S. expulsum utilizes a "ballistospore" mechanism, where the spore is actively and forcibly discharged from the stalk at maturity.
Amoeboid phase: In its trophic (feeding) stage, it exists as a small, uninucleate amoeba that feeds on bacteria and fungal spores.
Distribution and habitat
[edit]The species has a cosmopolitan but patchy distribution, often found on decaying plant matter, particularly dead attached parts of vascular plants.[3] Recent ecological surveys have expanded its known range to include diverse regions such as the Uludağ University Campus forest in Turkey.
Scientific significance
[edit]S. expulsum is studied to understand the evolutionary transition from single-celled amoebae to multicellular fruiting structures. Its active spore dispersal mechanism makes it a subject of interest in fungal and protist biomechanics.
