1-2 mm. broad. Main branches irregularly alternate, rather naked below, 



with lower branches the usually longest, becoming gradually shorter above ; 

 branches of every order are in similar mode of ramification, furnished 



along the margins with sharpish or often deltoideo-obtuse simple or 

 divaricated teeth. All the branches very patent arising on rather 

 roundish axils, straight or rolled up at apices. Glandular cells full of 

 yellowish contents are scattered beneath the cortex. In some cases 

 fronds bearing slenderer branches are seen which have an appearance 

 quite differing from the normal ones (fig. 2-3). 7'etrjspvres forming 

 irregularly roundish nemathecia, slightly elevated, and arranged often in 

 row along the margins or on the intramarginal surfaces of branches. 

 Cystocarfric warts are similar in the s'hape and position as tetrasporic 

 nemathecia. Colour deep r.d. Substance ri^id when fresh, soon 

 turning to subgelatinoso-membranaceous and the plant pretty well adheres 

 to paper in drying. 



Hub. : on rocks between tide-marks near low tide ; from Ryukyu 

 to Rikuzen; Tango and Echigo.
