Identification notes
When growing ‘typically’, this very common and widespread Didymodon is normally easily recognised. However, it is variable and some states may be confused with certain other small soil-dwelling acrocarps, especially D. vinealis and D. fallax.
As with other Didymodon species, careful examination under a compound microscope is usually essential to reach a satisfactory identification. The behaviour of the leaves when they dry can also be very helpful in differentiating D. insulanus from lookalikes (see resources below).
