THE BRYOPHYTA OF ICELAND 469 



Note. Entosthodon fascicularis is said to have been found by 

 Hornemann near Reykjavik, but no specimens of it can be found in 

 the collections, and the occurrence of this species in Iceland is not pro- 

 bable. 



FAM. BRYACE^E. 

 115. Leptobryum pyriforme (L.) Schimp. 



Very common in the majority of the districts of Iceland. This 

 species, especially in N. and NK. Iceland, is common on peat or damp 

 ground, but also on rocks, especially in soil-filled fissures. In S. Iceland 

 it occurs abundantly on damp rock-sides, in the clefts of tuff rocks, and 

 by rivers. It is only in N\V. Iceland that it appears to be rarer. There 

 it is common alone; the sea-side around Nautevri and Arngerdarevri,

but is otherwise rare in this part of the country and has only been 

 found close to the coast. 



The fruit ripens late in summer. In N. Iceland only some of the 

 fruits were ripe at the end of July. In specimens collected near Eyja- 

 fjordur by O. Davidsson in Sept. Oct. the capsules were ripe, but the 

 lids were not yet thrown off. 



116. Anomobryum filiforme (Dicks., Lindb.) Husnot. 



E. Iceland: Hornafjordur!; Berufjordur!; Stafafell!. W. Iceland: Pa- 

 trcksfjordur!, at an altitude of about 150 metres; Botnsdalur!; Esja, 

 Modruvellir !, at an altitude of about 200 metres; Alafoss!. S. Iceland: 

 Fljotshlid, common!; Eyjafjall, common!. 



Rather common in E. Iceland as far as Berufjordur, and in W. Ice- 

 land; common in S. Iceland; not found in the northern part of the country. 

 It grows, as a rule, scantily on damp rocks, mixed with other mosses, 

 such as Blindia acuta, Ancectanyium compactam, Amphidium lapponicum, 

 Anenra pinguis, etc., occasionally, however, also in large, pure cushions. 

 In S. Iceland it occurred everywhere on the faces of damp tuff rocks, 

 mixed with other mosses. Fruit was found only near Holt in S. Iceland. 



117. Anomobryum concinnum (Spr.) Lindb. 



S. Iceland: Hrutafell!. 



It was growing here rather scantily on the face of a damp tuff 

 rock, mixed with Blindia acuta, Metzgeria furcata, Barbula rubella. B. cy- 

 lindrica and Mynrella julacea. 



llcS. Plagiobryum Zierii (Dicks.) Lindb. 



E. Iceland: Stafafell!; Berufjordur!. N. Iceland: Myvatn (Grl.)!. 

 NW. Iceland: Arngerdareyri !; Patreksfjordur!. W. Iceland: Nordredalur 

 by Borgarfjordur!; Esja, in several places!; Lundur!; Bardshellir Grl.)!;
