Sporophytes are rare in Sphagnum microcarpum, which grows over bare soil in a manner similar to that of S. cyclophyllum and S. fitzgeraldii. It is now recognized as separate from S. cyclophyllum, with which it has been treated as synonymous in the past. Besides the microscopic differences, S. microcarpum has a compact upright growth form quite unlike that of typical S. cyclophyllum. Sphagnum microcarpum is nearly always branched whereas S. cyclophyllum is nearly always simplex.

The name Sphagnum mobilense Warnstorf also has been applied to this taxon.
