Anomodon attenuatus (Schreb.) Hueben. 

 Rocks and base of trees. Common in the vicinity of Lake Placid. 

 Mrs Britton. 



Anomodon apiculatus B. & S. 



Base of trees. Common. This is the most abundant species of the 

 genus and like Neckera pennata and Leucodon julaceus it prefers the 

 trunks of living trees, though unlike them it is usually found at the base 

 of the trunk where it forms dense dark green mats. Mrs Britton. 



Pylaisia velutina B. & S. 



Trunks of trees. Common. Forming delicate glossy light green 

 patches. Mrs Britton. 



Pylaisia intricata {Hedw.) B. & S. 

 Trunks of trees. Adirondack lodge. Less glossy and darker green 

 than the preceding. Mrs Britton. Wood farm and near Mountain View 

 house. Closely resembling the preceding species, but having a shorter 

 less cylindric capsule and a shorter beak to the lid. Both species fruit 

 freely. ' The genus name is variously written by different authors. 

 Beside the form here used we have Pylaiea, Pylaisaea and Pylaisiella. 



Climacium dendroides (Z ) W. &M. 



Damp or wet ground along streams and in swamps. Vicinity of Lake 

 Placid. Mrs Britton. Banks of the Ausable above Brewster's mill. 



The species of Climacium attract attention because of their large size and 

 tree : like aspect. When fertile each plant usually bears irom five to 20 cap- 

 sules on long erect pedicels. In C. dendroides the lid remains attached 

 to the columella. Both species have semiaquatic states which have been 

 distinguished as varieties. Mrs Britton. 



In the Manual, the principal divisions of the genus Hypnum are 

 regarded as subgenera, but many bryologists now regard them as valid 

 genera. We have followed the Manual. 



THUIDIUM 

 Hypnum abietinum Z.

 a darker green color than the other. 



Hypnum Blandovii W. & M. 



Mossy shaded places between the road and the river near the Notch 

 house. Fertile.
