The bank-and-path moss with translucent, crosswise-rippled leaves that crisp up when dry. A hairless cousin of the haircaps, and an easy one to learn.

Apple moss (Bartramia pomiformis)

The upland rock moss you can name from across a path, by the rows of tiny green apples it hangs out when it fruits.

Silky wall feather-moss (Homalothecium sericeum)
