USF Herbarium (Griepenburg s.n., 4 Apr 1970, Highland
Hammock State Park)
The leaves are scale-like, with small roundish to squarish cells with multiple papillae on both sides. As in other members of the Thuidiaceae, leaves on the main stem are larger than on the branches. The midrib extends 2/3 to 3/4 of the leaf length. Spore capsules are asymmetrical and bent to the side.
The related genus Thuidium differs in that papillae are found only on the lower surface, and there is usually only one per cell.
This species is found throughout state but lacking in the southern Atlantic counties. It is also found throughout eastern N. America, Europe, and south into South America.
Also found in Florida, but very limited in distribution and distinguished on minor characteristics are:
C. involvens, southern Florida north to Volusia County, but with major gaps.
C. pygmaeum, 2 records: Jackson and Manatee counties
C. schistocalyx : Highlands, Miami-Dade counties
The species has previously been known as Hypnum minutulum or Thuidium minutulum.
