Discussion

The sporophytes of Sphagnum wulfianum are moderately common. This is the most dry-growing species in North America, typically growing in association with Sphagnum centrale, S. girgensohnii, S. russowii, and S. squarrosum. It is easily recognized as the only species that regularly has more than six branches per fascicle. The Lycopodium clavatum-like growth habit and conifer swamp habitat along with the strongly 5-ranked branch leaves make it even easier to recognize in the field.
