*C. LiNtni Kiitz. f. pulvinata, nova forma. This variety of C. 

 linum forms intricately interwoven cushion-like masses, not widely 

 spreading fleecy webs, as in the typical form. It grows entangled 

 among Corallines and other algse, entirely covering them with its 

 yellowish green fronds. Unlike the typical form, this variety grows 

 in tide pool among the rocks at about half-tide level, and in places 

 where there is no admixture of fresh water — not on mud in brackish 

 water. ^ There is no important difference between the typical form 

 and this variety in respect to width of filaments and length of 

 joints; if anything, the variety is rather the more slender of the two.
