Delicate Fern Moss, Fern Moss
The delicate fern moss is perfectly named, reproducing the bipinnate or tripinnate structure of many ferns on a Lilliputian scale. These mosses are native to eastern North America, Alaska, Europe, the Caucasus, Siberia, Asia, Mexico, and South America.
Identification: “Fern fronds” are 1-3" (3-8 cm) in length, and adorn living and dead branches, as well as moist, shaded soil, humus, rocks, logs, or stumps. Fern moss may appear as deep green, yellow green, or orange-brown. The orange-brown coloration is not (necessarily) an indicator of poor health.
