Mosses of Central Florida 15a. Physcomitrium collenchymatum
The species previously posted under this name was misidentified. It is now re-posted under the correct name of Physcomitrium pyriforme. The latter species is common in Florida and elsewhere in the U.S., while P. collenchymatum is rare.
Physcomitrium collenchymatum is a much smaller plant, up to 4 mm high and with a capsule stalk 2-3 mm long, compared with P. pyriforme, which is typically 4-10 mm high, with capsule stalks up to 14 mm long.
My apologies for the previous misinformation.
