Crihraria. 59 



Gregarious, 1-5 — 2 mm, liigh, resembling superficially C. 

 intricata, but distinguished by the nodes of the network being 

 almost circular in outline, and without the prominent angles 

 from which the delicate strands spring in the last-named 

 species. 



Cribraria intricata, Schrad. (f. 11 — 13). 



Sporangia globose, erect, stipitate, ochraccoics hrown, calyculus 

 ocmpying half the sporangmm, margin dentate, nodes of network 

 numerous, containing granules, colowed, irregidarly angular, 

 with several large, jjointed, marginal prqfcetions, connected by

 diameter.
