respects the thallus, to some extent, with C. delicata, but yet 

 different, and exhibiting perhaps rather the ultimate if scarcely 

 reached type of that of C. Papillaria. The granulate condition 

 passes into a fine-powdery one; but the turbinate and cup- 

 bearing podetia suggest resemblance to a minute C. Cornucopi- 

 j rather than to any C. macttenta. 



30. C. cristatella, Tuckerm. ; thallus squamulose, the squam- 

 ules minute, but at length rather elongated, cut, and crenate ; 

 podetia of middling size ; cylindrical often ventricose and not 

 rarely elongated; cartilagineous-corticate : smooth, warty, or 

 wrinkled, or beset at length with squamules ; not forming cups, 

 but the dilated summits passing into fastigiate (fertile) branch- 

 lets ; from yellowish- at length ashy-green ; apothecia scarlet, or 

 now yellow (b, oclirocarpia). - Obs. Lick. 2, 1. c.p. 394. C.

 Illinois, Hall. - A state with densely squamulose podetia (f. 

 vestita) now very like the southern C. pulchella, has occurred 

 in Massachusetts, and New Jersey, Miss Biddlecome. - A re- 

 duced form, as I cannot but consider it, with conspicuously 

 powdery squamules, and the short, simple apothecia now epi- 

 phylline (v. paludicola) inhabits Cypress, and other swamps; 

 and corresponds closely with' the European C. Cornucopioides v. 

 incrassata. - Some small forms of the present species resemble 

 greatly (7. Floerkiana, Fr. ; but the two lichens are quite dis- 

 tinct, and C. cristatella might rather be regarded as standing in 

 the same relation to C. Cornucopioides as C. sympliycarpa to C. 

 pyxidata. - C. substraminea, Nyl. Syn. 1860, was founded on 

 the ochrocarpious form of the present, with which the very dis- 

 tinct C. kpidota of the Ochroleucce, was mistakenly joined. 



31. C. leporina, Fr. ; thallus squamulose, squamules minute, 

 narrowed, erose-lacinulate, finally disappearing ; podetia frutic-
