Aphanothece saxicola is a unicellular cyanobacterium in the order Chroococcales, forming colonial aggregates embedded in thick gelatinous sheaths on rocky substrates in freshwater and terrestrial environments. Its colonies appear as thin, greenish to brownish crusts on wet rocks, stream banks, and moist cliff faces. It contributes to biofilm formation and can fix atmospheric nitrogen under certain conditions.
