 gen. /. 47./. I. Dilkn. mufc. t. 14./. 6. A-M.) 



Common Cup-Mofs, or Lichen. AngUs. 



Jn heaths, and on banks and rocks, and about the 

 roots of old trees. 



The ground of this is at firfl: a granulated cruft 

 only, v.'hich grows afterwards to fmall leaves, 

 irregularly laciniated, green on the upper fide, 

 white underneath ^ at the bafe of which leaves 

 ariie grey afh-ca!our'd funnel fliap'd cups, from 

 half an inch to an inch high, fomctimes cover'd 

 v;ith a fariiiaceous powder, ai:d lometurjes not, 

 flender at the baie, but Vv'idely expanded at the 

 rim. The Ralk of the cup, or funnel, is tu- 

 bular, but not throughout, for the cup itfeif is 

 concave and clofed at the bale. The lira, if 

 attentively examined, is linely jrenated. 



This is the mcft common and fimple appearance of 

 this Lichen, but it varies greatly. 



Sometimes the margins are furrounded v/Ich brown 

 fefTiIe tubercles, which in decay turn to a hlackilh 

 colour. And fometimes thcfe tubercles are lup- 

 ported on fhort peduncles, and begin to affume 

 the appearance of fecundary cups. It is figui'd 

 in both thefe ftatcs by Dillenius^ t. 14./. 6. C. 



3t is alfo frequently proliferous, and' that in two 

 different v/ays. Sometimes fecondary cups grow 

 out of the margins of the firft-, and others again 



out
