338 XXIV. REPRODUCTION OF THE HIGHER FUNGI AND LICHENS. 



interior shows itself to be constructed of delicate, shortly seg- 

 mented, approximately radially-arranged threads, single or in 

 bundles (compare the Figure). The long axis of the organ is 

 traversed by a cylindrical cavity, which receives the rod-like 

 conidia, which are segmented off from the ends of the threads. 

 Through the upper opening of the pycnidium the conidia can 

 make their exit. These pycnidia were formerly considered to 

 be the male sexual organs, and distinguished as spermogonia. 

 If Anaptychia is not at our disposal, various other lichens 

 show pycnidia, such as Pannelia (Physcia) parietina, Verrucaria 

 nitida, Collema melcenum, or Cladonia rangiferina.
