Frond forms a roundish mass with branches intricated and 

 attached at points to each other. Main branches are flexuose, more 

 or less dichotomous with alternate branches which are mostly curved 

 and loaded with short, secund, very patent, thorn-like ramuli. All the 

 branches are compressed and taper to sharp point rising with not- 

 constricted bases. Plant attains the height of 6-10 cm. with the 

 breadth of 1-2 mm. in broader parts. Sori are formed around the 

 mostly basal swollen parts of ramuli. Substance is slightly cartilaginous 

 when fresh, but soon softens changing the colour at the same time 

 from blood-red to yellowish-red. 



Hub. : On rocks between tide marks. Prov. Shima, Enoshima 

 and Misaki (Prov. Sagami), Prov. BoshyO, Onahama (Prov. Iwaki). 

 Sori : spring. 



Remarks : To me the substance does not seem to be " rather 

 stouter than the majority of species of the genus " as Holmes states.
