Mr. W. Mitten on the Mosses and Hepaticce of Sussex. 323 



104. O. cupulatum, Hoffm. 



Rare : on tiles at Balcombe. Mr. Borrer has gathered it at Stor- 

 rington, and Mr. Jenner at Lewes. 



105. O. tenellum, Bruch. 



Plentiful on trees about Hurstpierpoint and Henfield, but perhaps 

 not generally common. 



106. O. affine, Schrad. 



Abundant on trees, more rarely on tiles. 



107. O. speciosum, Nees ab E. 



Very rare : one patch was gathered by Mr. Spruce in an orchard 

 at Henfield ; it has since been carefully sought for in the same place 

 without success. 



108. O. rupestre, Schleich. 



O. rupincola, Funk. Eng. Fl. 

 In very small quantity on an ash-tree by a rivulet near New Close, 

 near Hurstpierpoint. 



109. O. striatum, Hedw. 

 O. leiocarpum, B. et S. 



Frequent on trees. 



Following C. Miiller, the old name has been used for this moss, 

 which, if it is the species so named by Hedwig, ought to retain his 

 name, bad as it may be. 



110. 0. Lyellii, Hook, and Tayl. 



Common on trees : unfrequent in fruit, which is mostly found in 

 woods. 



111. 0. pulchellum, Smith. 



Rare : in several places near Hurstpierpoint and in Tilgate Forest. 

 On hazel at Midhurst, and on bushes on the beach near Shoreham, 

 Mr. Borrer. 



112. O. crispum, Hedw. 



Not unfrequent, especially on beech-trees, in woods near the Downs. 



A somewhat smaller state than usual is sometimes met with, and 

 has been referred to O. crispulum, Bruch, but it does not quite cor- 

 respond with continental specimens. 



113. O. Eruchii, Hsch. 



O. coarctatum, B. et S. 

 Common on trees in woods, particularly in the forests, where it 

 abounds. 



114. O. Ludwigii, Schw. 



Very rare ; on beech-trees on the north side of Woolsonbury Hill. 

 Only three small tufts have been seen.
