meterspor

Meterspor is a term that has appeared in limited scholarly contexts as a provisional label for a spore-like structure observed in certain fungi and algae under microscopy. It is not an established taxonomic category and is not widely used in current fungal or algal nomenclature. The word derives from combining meter (measure) with spor (spore), reflecting its descriptive origin rather than a defined lineage. In the sparse reports where it appears, meterspor refers to spores described as having specific size ranges and distinctive wall features. Because criterial definitions varied between studies and reproducibility is uncertain, meterspor has remained a tentative, nonstandard designation rather than a formal taxon. It is not assigned to any recognized genus or family, and no formal description meets contemporary taxonomic standards. If discussed, meterspor would be considered part of an organism’s sporogenous stage, with dispersal following general spore biology; however, there is insufficient evidence to define its ecological role or host associations. The term appears in historical microscopy-focused literature, and later reviews have largely abandoned it in favor of conventional spore terminology. See also: Spore, Sporulation, Mycology.
