straight or slightly curved, ends rounded, often minutely 

 biguttate, 8-10x3-4/1 ; sporophores not seen. 



On dead stems of Pedicularis racemosa, near Pagosa Peak, 

 6 Aug.; n. 45. 



This was previously collected by Mr. Baker on Pedicu- 

 laris, at Four Mile Hill, near Steamboat Springs in Northern 

 Colo., July 22, 1896. It was referred by Ellis to the com- 

 posite P. herbarum. It seems, however, to be sufficiently 

 distinguished from that assemblage of forms by its larger, 

 scattered and not gregarious hycindia. In this vast genus 

 spore characters alone furnish an insufficient guide to the 

 recognition of species. 



PHOMA HERACLEI, n. sp. Pycnidia scattered, prominent, 

 black, subglobose, not collapsing, about mm., finally ex- 

 posed by the shredding away of the thin epidermis, of firm 

 cellular parenchyma, cells 4-6x6-8^; shorules oval, hyaline, 

 usually with a minute gutta near either end, about 8-10 

 x6/i. 



On dead stems of Heracleum lanatum, near Pagosa Peak, 

 9,000 feet, 20 Aug.; n. 46. 



PHOMA LUPINICOLA, n. sp. Thickly scattered on large, 

 often slightly whitened areas; pycnidia long covered by the 

 thin epidermis, black, prominent, subglobose, not collapsing, 

 about 150-175/i, membranous, of distinctly cellular paren- 

 chyma, cells 6-12/x. averaging 8/* in diameter, ostioles simply 

 perforate, the opening about 20/u, in diameter; sporules 

 numerous, regularly oval or subcylindric, ends broadly ob- 

 tuse, quite uniformly with a minute gutta at either end, 

 about 8-10x4-5/4. 



On dead lupine stems at Durango, 18 March ; n. 47. 



RHABDOSPORA GUTIERREZ: AE, n. sp. Pycnidia scattered, 

 buried but finally somewhat protruding through the thin,
