Isothecium stoloniferum is an extremely variable species strongly related to the less variable I. myosuroides. Isothecium stoloniferum differs in its genetic composition (K. Ryall et al. 2005). There is a morphotype of I. stoloniferum that resembles I. alopecuroides, but the leaves are not cucullate and the apex is acute and strongly toothed. This morphotype appears to be most frequent on boulders or outcrops in and beside streams, often in well-drained but humid sites.
The predominant morphotype of Isothecium stoloniferum has pinnate, acute-branched plants, sometimes with a stipe emerging from the primary system or proliferating from the secondary system, and can appear dendroid, especially when humid. The shoots are not julaceous, and flagelliform branches are infrequent. This morphotype tends to produce short stolons adventitiously usually near the base of the stipe. Another morphotype mimics I. myosuroides and is often impossible to distinguish; it is commonly epiphytic and tends to produce flagelliform branches; some populations can be composed entirely of flagelliform branches. Although the alar cells are less pronounced in this morphotype, the long-acuminate, strongly toothed leaves are characteristic.
