Descriptive notes

Anomodon attenuatus is an olive green, loose, and irregular plant that forms into a "mat" shape. Branches can taper into a stringy tail, a blunt tip, or a knobby pom-pom. Leaves are triangular, with a round base, and end in a small "tooth" at the apex. They fold around the stem, and wrap in to chains. The leaf edges are smooth. Cells are papillose.

Capsules, when present, are upright, cylindrical and light shades of brown. They are between 2 and 3mm long. The whole plant is "short", and reaches approximately 1 inch from the rhizomes to the apex of the tallest leaf.

General distribution and habitat

A. attenuatus are found on the bases of tree trunks, in soil backs and on rocks (specifically calcareous cliffs and boulders).

Campus distribution

I found my specimen on a dry boulder (5ft. x 5ft.) 100 meters from the pond. The plant took up almost the entirety of the boulder's visible surface.

Found another specimen growing near the pond, this one on the base of a maple tree. Jkendrick 20:40, 16 April 2013 (UTC)

Two more specimens were found in the forest off of the Blue Trail under different clearings in the canopy, one in a nook at the base of a hardwood stump, and one on a small boulder sitting on the ground. Gfredericks 19:32, 30 April 2013 (UTC)

Other notes

A. attenuatus is commonly known as the poodle moss.
