Identification notes
This is a small, scruffy-looking moss. Look for low-growing patches of slender, golden-green plants without hair-points on the ground – sometimes extensive but more commonly among other bryophytes and low-growing plants. Like C. pyriformis and some other species of Campylopus, detached shoot tips (which act as vegetative propagules) are frequently seen scattered about on the colonies.
If you think you’ve potentially collected some, do check it microscopically to be sure. This will involve cutting transverse leaf sections to see if stereids bands are present (they shouldn’t be) and using a new razor blade to slice multiple times across dried shoots should give at least a few decent sections.
