A small form witli the tlialliis ptilviiiale, polyphyllous, and the lobes nu- 

 merous, congested, and Aariable at tlie niar<rins. It is connected with the 

 tvpe by intermediate states, and is but rarely seen in its more charac- 

 teristic form. Apparently it never occurs iji fruit.

Though generally regarded as a variety of the preceding, the different 

 characters of the thallus and the larger spores render it as distinct a 

 species as most of the others in the genus. It may at once be recognized 

 by the peculiar flocculose and usually more or less squamulose upper 

 surface of the thallus, which is sometimes paler in colour, lacunose 

 beneath (form hrotera, Ach. Meth. p. 103), and occasionally in old plants 

 becomes subcribrose at the margins. The apothecia are extremely rare 

 in Great Britain, and are sparingly visible only in one or two specimens.
