zone, but in shallow water. I have usually found it growing at- 

 tached to stones and once only as an epiphyte (cfr. P. latifolia). 



I came across large vigorous examples bearing sporangia in 

 June and July. 



Found in the following piaces: — Str. : Sundene between Thorsvig 

 and Kvalvig (!); Ost.: Glibre (!). 



DESMOTRICHUM Kutz.

 tab. 11. 



Once only in June some small specimens were found, but 

 they bore quantities of plurilocular sporangia and agreed exactly 

 with Reinke's description and figures. They grew in shallow water 

 and were gathered together with Cystoclonium purpurascens amongst 

 which alga I lirst found it on examining the material more closely 

 here in Copenhagen, so I cannot say to what substratum it grew 

 attached.

PHYLLITIS Kutz.

Occurs in the littoral zone, especially on the open sea-shore, 

 but also in sheltered situations. It grows both in piaces where it 

 is left dry at ebb-tide and in rock -pools. It is usually found at- 

 tached to rocks and stones but also occurs, though rarely, as an 

 epiphyte, e. g. on Himanthalia lorea. In Kalbakfjord it grew at the 

 mouth of a stream where the water was occasionally quite fresh. 

 Fructifying specimens were found in April, May, June, July and 

 November. According to Reinke (Algenflora westl. Ostsee, pp. 61— 2) 

 this species is a winter and spring plant in the western part of the 

 Baltic; judging from the material I have had for examination it is 

 met with all the year round around the Færoes, where at any rate 

 it occurred abundantly during summer. 



This species is common, especially along the exposed eoasts of 

 the Færoes. 



126. Ph. zosterifolia Reinke, Algenflora westl. Ostsee, p. 61. 

 This alga which is doubtless rather rare along the Færoes was 

 found both on exposed coast and in somewhat shellered localities;
