How to recognize Anacamptodom splachnoides: This moss forms dark green dense mats. The leaves are usually ovate-lanceolate Iegg-shaped to spear-shaped) with a costa or midrib that extends above midleaf, and with cells that are oblong rhombic. It might be confused with an Amblystegium except for the erect symmetric capsule that is strongly constricted below the mouth when the spores are ready for dispersal, often so much that a mass of green spores protrude. The first picture above shows this condition except for one capsule where the operculum or capsule lid is still in place. When dry the eight triangular exostome teeth of the peristome are strongly recurved against the capsule. These teeth move back and forth depending on the humidity and open up when conditions are right for spore dispersal.
Where to find Anacamptodon splachnoides: This moss is found in knotholes, forks and crevices where moisture collects on deciduous trees.
