Scattered over the under side of the leaves in the form of little jet- 

 black threads, scarcely |- a line high, which at first sight seem to be 

 part of the matrix. Flocci densely fasciculate, somewhat free at the 

 very base and at the apex. Spores oblong or clavate, very dark, trans- 

 versely multiseptate, with a few vertical divisions about y^oo- ^^ ^^

 At first orbicular, but becoming at length lobed and irregular, 

 clothed beneath with a dense spongy coat, consisting of red-brown 

 flocci, without any separate rooting fascicles, distinctly and repeatedly 

 zoned 5 margin obtuse, sometimes slightly reflected. Hymenium
