peristome is ^vell sllo^vn, the outer teeth deeply sulcata on the median 

 lino, and very highly cristate-lamellate ^yithin. The lid (not descrihed hy

Canoe Camp, Oct.-Nov. 1912 (Xo. 34). 



This pretty and delicate little moss covers the surface of large leaves in a 

 very thin, closely appressed sheeL It belongs to a small group, to whicl 

 the two species named in the diagnosis and one or two others belong, of 

 somewhat similar habit and leaf-structure, and with extremely delicate seta. 

 In the present case the seta is much finer than the finest human hair. Their 

 generic position is somewhat doubtful ; they h:ive been referred to both 

 Trirhosteleuvi and laxUheliam, and, indeed, as Fleischer states ('Nova 

 Guinea,^ viii. 740), form a connecting link between the two. The lid is 

 generally short and unlike Trkhosteleam, and the form and position of the 



capsule varies much. 



T. Levien differ.^, in addition to characters montioned abovo^ in the more 

 distinct pa[)illa} and larger spores (25-30 /i). T. Wernevi is larger in all its 

 parts. 



The alar cells are not at all stron<ilv marked, being confined to 1-2 oval, 

 hyaline cells, much larger than the adjacent ones, but not at all conspicuous 

 as compared with many sj)ecies of the genus.
