median and second lobes; the base of the second lobe is pro- 

 longed cephalad into a fingerlike process continuous with a 

 striated band terminating at the anal plate (Plate III, fig. 1). 

 The lateral margins indented, marking five sutures along which 

 are single rows of minute quadrate scales with serrate apical 

 margins (Plate III, fig. 2). Circumgenital glands in two 

 groups, each of about 150 orifices.

 acutiflorum. The colonies of this scale are usually completely 

 covered by the thick, felted, brown masses of a fungus, Septo- 

 basidium bakeri Patouillard.
