evolutis multifidisinterdum confertis ctapotheciis symphyearpis." 

 This description applies well to this specimen, in which there is a 

 decided reaction K+ in the folioles, and would seem to point 

 to its separation from squamosa, which has a different reaction, 

 K-. 



22. " CI. squamosa, Hofftn., v. ventricosa, Fr., glabriusnda." 



Here, again, there is the reaction K+ in the folioles of the 

 podetia ; and it may probably be also referable to frondosa, Del. 



23. " CI. squamosa, Hoffm., v. asperella (Flk.), Korb." 



K-C-. 



24. " CI. furcata, Hoffm., v. stricta, "Wall. (syn. v. stenozosia, Mass. 



Ttal. 196)." 

 K+ C + . =Tuck. L. Amer. 33, but with slight reaction. 

 Mass. Ital. 196 has full reaction, K + C + , and is therefore 

 referable to pungens. 



25. " CI. furcata, Hoffm., v. racemosa, Hoffm." 



K+ C + . = Coem. 183. This specimen has so decided a 

 reaction that I cannot hesitate in referring it as a state of 

 CI. pungens, var. foliosa. 



26. " CI. furcata, Hoffm., v. corymbosa (Ach.)." 



K + C + . =Coem. 189. The decided reaction refers this 

 also to CI. pungens. 



27. " CI. pungens (Ach.), Fr., f. foliolosa." 



K + C + . The true plant. 



28. " CI. pungens (Ach.), Fr., f. valida, Rabh. (syn. CI. muricata, v. 



Euganea, Mass. Ital. 191)." 

 K+ C + . In my copy of Mass. Ital., No. 191 is a much 

 stronger plant, and different in aspect from this specimen. 



29. " CI. pungens (Ach.), Fr." 



K + C + . = Mudd, 54 & 55 ; M. & N. 754 ; Leight. 1 6. 



30. " CI, pungens (Ach.), Fr." 



K+C+. 



31. " CI. degenerans, Flk., f. pleolepis, Ach." 



K+ C + . The decided yellow reaction makes this =lepidota, 

 Ach. 



32. " CI. degenerans, Flk., f. phyllocephala, "Wallr., Korb." 



K+ C + . The decided yellow reaction refers this also to 

 lepidota, Ach. 



33. " CI gracdis, Hoffm., v. aspera (Ach.), Flk." 



K + C + . The reaction and aspect refer this to CI. pungens, 

 var. foliosa. 



34. " CI. gracilis, Hoffm., v. elongata (Ach.)." 



K+ C + - The reaction and the peculiar character of the 

 cortical layer identify this with CI. ecmocyna, Ach. 



35. " CI. cornucopoides (L.), Fr., v. externa, Hoffm." 



Kf+C + . 



36. " CI. bacillaris (Ach.), f. davata-polycepluda." 



K- C-. 



37. " CI. bacillaris (Ach.), f. clavata, Ach."
