The capsules of this moss have a very neat and polished 

 appearance. It may be confounded with Grimmia ovaia ; 

 but, as Mr. Turner, its original discoverer, has rightly ob- 

 served, the want of the diaphanous points to the leaves will 

 always sufficiently distinguish our present plant. The teeth 

 are broad, often cleft, as in Dicranum^ but more deeply* 

 The habit is very nearly that of Grimmia ovata. 



20. LEUCODON. 



GEN. CHAR. Fru&stalk$]&tett&} PeristoThe single, of 

 32 teeth, closely united in pairs ; Calyptra dimi- 

 diate. (TAB. II.) 



We have adopted with much satisfaction Schwaegrichen's new 

 genus Lezicodon, published in the second part of his valuable 

 Supplement to Hedwig's Species Muscorum. The only British 

 species has been occasionally thrown among the Dicrana^ Tri- 

 chostoma, and Pterogonia; from any of which an attentive con- 

 sideration of the lateral fruit, deeply divided teeth, and dimidiate 

 calyptra will keep its genus distinct. The teeth are very nar- 

 row, whitish, and sometimes appear united at their tops ; but this 

 appearance may arise from our taking as the subjects of our ob- 

 servations capsules in too young a state ; since in specimens which 

 have been gathered fresh from the trees, and in a state where 

 the lid had naturally fallen off, the teeth appeared as deeply di- 

 vided, and the divisions as separate, filiform, and jointless as in 

 some species of Didymodon*
