fruits ripen during July; near Seydisfjordur many were found to be ripe 

 on July 1st, and in South Iceland ripe capsules were collected between 

 1015 June. 



Splachnum Icnue is recorded byGliemann to have been collected 

 by Morch, but the specimens in the herbarium collected by Morch 

 belong partly to Splachnum sphcericum and partly to S. vasculosiim. 



i 



112. Splachnum vasculosum L. 



Commonly distributed. 



Like the preceding species it grows, often abundantly, on cow-dung 

 in wet marsh} r ground. It is most frequent in the lowlands, but ascends 

 also as far upwards as to the mountain heights. Thus at Seydisfjardar- 

 heidi it was common up to about 600 metres above sea-level, and in 

 NW. Iceland also it was found as far upwards as about 500 metres. 

 Such forms from mountain heights are as a rule low in growth and 

 have short setas. 



As is the case with Splachnum sphcericum the fruit ripens at diffe- 

 rent times during the course of the summer, from the first half of June 

 into August. 



Splachnum ampullaceum, as recorded to have been found by Koenig, 

 is undoubtedly nothing else but S. uasculosiim. 



FUNARIACE^:. 

 113. Funaria hygrometrica L. 



Commonly distributed all over the country. 



It usually grows on peaty ground, associated with Dicranella crispa, 

 Polytrichum uracile, P. juniperinum, Bryum spp., etc., but is also found 

 on humus-covered rocks and on tuff. It does not occur abundantly, as 

 a rule, and it does not ascend to any great height, doubtless not higher 

 than to an altitude of 300400 metres. The fruit ripens in the be- 

 ginning of August. The spores vary considerably in size in this species, 

 from 0.011 to 0.021 mm., in plants which otherwise show no deviation 

 from the type. 



114. Entosthodon ericetorum (Bals. et De Not.) Br. eui. 



Funaria obtusa (Dicks.) Lindb. 



W. Iceland: Kleppjarnsreykir in Reykholtdalur!; Englandshver!. In 

 both places with ripe fruit (2530 July). 



This species grew in the above localities on warm ground. Near 

 Englandshver it grew along the outlet of a spring. Near Kleppjarns- 

 reykir it was found both on a stone standing in water of a temperature 

 of about 50, mixed with Blimlia acnta, Aneura multifida, Anthoceros 

 and Scapania irrigua, and also on warm, damp ground mixed with 

 Fissidens osmundoides.
