THE BRYOPHYTA OF ICELAND 409 



25. Alicularia geoscypha De Not. 

 Nardia minor (Nees) Arnell, A T . haematosticta Lindb. 



Commonly distributed all over Iceland and, as a rule, fruiting. 



This species doubtless occurs as frequently in the lowlands as on 

 mountain heights upwards to the limit of plant-growth. It is generally 

 met with on damp gravelly ground associated with other Hepaticas, for 

 instance by streams with Cephalozia bicuspidata, Scapania subalpina, S. 

 curta, Lophozia alpestris and L. Wenzelii, or on damp gravelly ground 

 on rock\ f flats with Pohlia gracilis, P. commutata, Aongstroemia longipes 

 and several other species. On mountain heights, especially in NW. 

 Iceland, it generally grows in company with Anthelia Jnratzkana on gra- 

 velly flats irrigated by melting snow. 



\ar. insecta (Lindb.) K. M. was collected near Isafjordur (at about 

 300 metres alt.) together with the type. 



Note. Alicularia compressa (Hooker) Nees is figured in Flora Danica, 

 tab. 1772, fig. 2, and is recorded to have been found near Gronnefjord(?) 

 by Morch, but no specimens of it are to be found in the collections. 



26. Eucalyx subellipticus (Lindb.) Breidler. 



E. Iceland: Berufjordur!; Seydisfjordur!. N. Iceland: Hof near Eyja- 

 fjordur (O. D.) !; Oxnadalur. NW. Iceland: Kaldalon!; Laugarland!; Grun- 

 navik (at about 350 metres alt.); Gnupsdalur!. W. Iceland: Gilsbakki: 

 Esja, several places!; Kolvidarhol!. S. Iceland: Thingvellir, several places!. 

 It has been collected everywhere in fruit. 



It is no doubt rather common but often overlooked on account of 

 its diminutive size and resemblance in habit to the far more frequently 

 occurring small species of Alicularia and Haplozia, with which it is 

 generally associated. It is usually found on damp gravelly ground, 

 more rarely on damp rocks or in lava-clefts; now and then in unmixed 

 tufts, but generally mixed with Alicularia scalaris and A. geoscypha. Sca- 

 pania curta, Dicranella crispa, Pohlia spp., etc. Near Hof it grew mixed 

 with Haplozia pumila; in Almannagja it occurred in many places at the 

 bottom of clefts or on humus-covered ledges associated with Lophozia 

 alpestris, Alicularia geoscypha and Scapania subalpina. Near Seydisfjordur 

 it occurred creeping over stones by the river and mixed with Haplozia 

 atrouirens. 



27. Haplozia crenulata (Sm.) Dum. 



Nardia crenulata. 



Near Geysir (Morch; Stp.!); figured in Flora Danica, tab. 1774, 

 fig. 1, u in uliginis Islandiae frequens, A. Morch.'' Common near all the 

 hot springs in Reykholtdalur!, Reykirdalur !, on Biskupstungur!, on Rey- 

 kjanes (Ostf.)!, near Laugarvatn!, in Lundurreykjadalur! and near Myvatn!. 

 It was found also in W. Iceland: Borgarnes!, at several places along the 

 road; Lsekjarmot!, on wet ground in bogs. NW. Iceland: Laugarland!, 

 on boggy ground.
