... temperature and pH vary widely. Although most common in neutral and alkaline waters, stromatolites also are forming in several acid-sulfate spring and geyser systems in the Waiotapu geothermal area and at Lake Rotokawa. Growth of these stromatolites is partly mediated by a biota that is dominated by fungi...
