Geosiphon pyriformis is a glomeromycete fungus and obligate symbiont commonly found in soil. Glomeromycete fungi are usually arbuscular mycorrhizae that form a symbiotic relationship with vascular plants and brophytes. While most glomeromycete fungi form these arbuscular mycorrhizal (AM) relationships, Geosiphon pyriformis has not been observed in AM relationships with plants. Geosiphon pyriformis "may also be symbiotic with plants.

Description and significance
Nostoc punctiforme is a filamentous cyanobacterium that can be photoautotrophic, diazotrophic, heterotrophic, and/or symbiotic. This species of cyanobacteria has vegetative cells that can differentiate into heterocysts, spore-like akinetes, or motile filaments called hormogonia. This species is also broadly symbiotic, forming relationships with fungi, bryophytes, gymnosperms, and angiosperms. The genome contains a large number of unique genes that likely play essential roles in cell differentiation and symbiosis.- “An overview of the genome of Nostoc punctiforme, a multicellular, symbiotic cyanobacterium”
