II. Cyathia lufipes (Ell. & Ev.) 



Cyathus riifipes Ell. & Ev. Bull. Torrey Club, 24: 125. 1897. 



Peridia very slender, obconic, .8-1.5 cm. high, 3-6 mm. wide 

 at the top, 1-1.5 mm. at the base, outer surface lightish brown or 

 tow- colored, very shaggy tomentose, and with a quantity of red- 

 dish-brown mycelium adhering at the base, forming a felt-like tuft ; 

 inner surface smooth, dark gray, shiny ; sporangioles 2 mm. in 

 diameter, dark, almost black, shiny, depressed beneath ; spores 

 25—29 n long, 18-22 fx wide, thick- walled, granular within and 

 hyaline. {PL 15./. 14-16.) 



On old sods, "growing head downward," 



Kansas : BartJiolome'w ; Nebraska : Bates. 



This species is readily distinguished from the other species of 

 Cyathus with a smooth inner surface by its very slender elongated 

 shape and its light densely tomentose peridium, besides the char- 

 acteristic feature of the red felt-like mycelial tuft at the base, from 

 which the species derives its name. 



12. Cyathia Wrightii (Berk.) 



Cyathus IVrightii Berk. Grevillea, 2: 34. 1873. 



Peridia rather large, cup-shaped, 1.2-1.8 cm. high, .5-1.2 cm. 

 wide at the top, contracted somewhat at the base, then bulbose, 

 the bulb composed of mycelium and adhering earth ; outer surface 

 darkish brown, very rough, shaggy and encrusted with earth ; 

 inner surface smooth, shiny, darkish ; mouth entire, not fimbriate 

 though the fine hairs circle up about it; sporangioles dark, 1.5-2 

 mm. in diameter, shiny, flattened; spores 22-25 /" lo"g> 15-18 fx 

 wide. {P/. 16. f. 7-p.)
