MOSSES WITH A HAND-LENS l8l 



HARPANTHUS SCUTATUS (Web. & Mhor.) Spruce is a third 

 not infrequent species likely to be confused with the preceding, 

 but the plants are so much smaller (scarcely ^V of an inch in 

 width), that one who has seen all four will have no difficulty. 

 The leaves are short-ovate, more ascending. The spores mature 

 in May and June. The favorite habitat is old logs in damp places. 



SPHENOLOBUS MICHAUXII (Web.) Steph. is about the size of 

 the preceding, but is a plant of mountainous regions with a much 

 darker color ; the leaves are inserted nearly crosswise of the stem 

 and are almost sheathing at base ; when dry they are more or less 

 folded together. The perianth is cylindrical. On rotten wood. 



This plant was formerly put in the genus Jungermannia and 

 there are several plants of that genus as treated in Gray's Manual 

 that may be sought here. They are, however, for the most part 

 plants of smaller size and less frequent occurrence. Many of them 

 are confined to mountainous regions and many can not be well 

 determined with a lens. 



LOPHOZIA ( Jkmgermannia in part) 



This genus which has usually been treated as a subgenus of 

 Jungermannia consists of numerous species of creeping forms 

 with succubous leaves which are not much longer than broad and 

 are markedly toothed or cleft at the apex. Many are alpine or 

 subalpine. 



L,. BARBATA (Schreb.) Dum. is common in the mountains of 

 New England and New York on damp shaded rocks, some- 

 times on rotten logs or banks. It is rare or entirely lacking 

 in the southern portion of our range. The leafy stems are an 

 inch or more long and about T V inch wide. It usually grows 

 in flat tufts closely applied to the substratum, but occasionally the 

 stems are ascending or erect. The shade of green of the 

 plants depends upon the amount of light they receive ; in 

 full sunlight they have a yellowish-brown tinge. The leaves 

 are more or less quadrate in outline and are divided at the apex 

 into three or four teeth or lobes ; there are no other teeth or 

 marginal markings. The plants are dioicous and the antheridial 

 plants are slightly different from the spore-producing or female 

 plants as is shown in the figures. 



L. INCISA (Schrad.) Dum. In this plant the leaves are 2-6 

 lobed, but two of the lobes are larger and the leaf has a
