Thuidium delicatulum (Hedw.) Schimp.
Thuidium delicatulum (Hedw.) Schimp. var. repens Kindb.
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.
