smooth, of an aurora-red colour with a mixture of pink, subses- 

 sile HOOK. Scot. ii. 9. GREV. Fl. Edin. 463. 



Hob. On dead branches of the plane and ash trees, not un- 

 common in spring. 



" Smaller than the preceding, and far more depressed ; sur- 

 face not rounded, but gently convex or quite plane, soft, 

 becoming confluent and angular, often irregular from the 

 union of one or more together." GREVILLE. Yet it 

 is sometimes difficult to trace the limits between the spe- 

 cies, nor do I think it would be injudicious to unite them 

 under one name. 



3. T. granulata, brownish -red, rough and tubercular, subsessile. 

 PERS. Syn. 113. GREV. Crypt. Fl. t. 187. 



Hab. On dead branches of the sycamore, rare. 

 Diameter about a line ; blackish when old. 



81. CENANGIUM. 



1. C. Abietis, gregarious, coriaceous, subsessile, rugose, and 

 somewhat powdery? dull black, compressed ; when moist spread- 

 ing, the disk yellow. Sot. Gall- ii. 736. C. ferruginosum, GREV. 

 Crypt. Fl. t. 197. Peziza Abietis, MOUG. and NEST., No. 399. 



Hab. On dead branches of the Scotch fir, frequent. 



82. PEZIZA. 



OBS. The genuine Pezizce are shaped like a cup or saucer, and 

 in the smooth concavity or disk the seeds are placed, whence they 

 are discharged in the form of a fine powder. These seeds are 

 contained in linear tubes, placed erect, and in close apposition, 

 but it requires a good magnifier and a careful dissection to unfold 

 this structure. It is a remarkably beautiful genus, but from the 

 great number described the species are difficult to ascertain. 

 Their consistence is in general soft and fleshy ; they exhibit all 

 colours, vary much in size, and while the greater number grow- 

 on decayed wood, some prefer the naked soil. Unable to identify- 

 some of the minute species, I have chosen, as I have done in 

 other genera, rather to omit them from my list, than expose my-
