16 PLANTS BAKERIAN^E. 



time above timber line was always limited and that the 

 beauty and abundance of the flowering plants claimed our 

 attention, to the neglect of the Fungi. 



In the following list the sequence of families is that of 

 Engler & Prantl. In the few cases in which the generic 

 name used by us is another than that employed by Saccardo 

 in the Sylloge Fungorum, the latter is added in parenthesis. 



PERONOSPORACE.E. 



ALBUGO CANDIDUS (Pers.), Kuntze, Rev. Gen. ii: 658. 

 Little Kate mine, La Plata Mts., 11,000 feet, July 13, on 

 Sophia, n. 1084. 



BREMIA LACTUCJS, Hegel, Bot. Zeit. St. 39. Tab. 3. Man- 

 cos, 7,000 feet, June 24, on Agoseris, n. 1,089. 



PERONOSPORA ARENARI.E MACROSPORA, Farlow, Bot. Gaz. 

 ix : 38. Bob Creek, west of Mt. Hesperus, 11,000 feet, July 

 5, on Silene, n. 340. This corresponds very closely to speci- 

 mens collected in Illinois, and so determined by Farlow, 1. c. 

 The differences he so clearly pointed out between this and 

 the European P. Arenarise indicate it to be a distinct species, 

 but as our specimens are mostly without oospores we decline 

 to make the change, and write the name as above. 



PERONOSPORA PARASITICA (Pers.), Fr., Sum. Veg. 493. 

 Chicken Creek, west of Mt. Hesperus, 9,000 feet, July 6, on 

 Arabis, n. 1,085; also on Sophia, at Mancos, 7,000 feet, June 

 24, on Sophia, distorting the stems; n. 1087. This common 

 parasite was observed on various cruciferous hosts through- 

 out the region. 



USTILAGINACE.E. 

 SCHIZONELLA MELOGRAMMA (DC.), Schroet, Pilz. Schles.
