in diameter, pale orange or flesh-color, fringed with suberect, 

 pale, roughish, faintly septate hairs 110-150// long. Conidia 

 cylindrical, straight, hyaline, with a nucleus in each end, 

 6— 8. 5 X 1. 5— 2ytf, concatenate on branched basidia and formed 

 by the constriction of the upper part of these branches (figs. 

 5 and 6.) — On dead stems of Astragalus flexuosus and A. 

 Drummondii. Sand Coulee, Cascade co. , Montana, May 1889. 



This is closely allied to V. gilva (Pers.) but differs from 

 Saccardo's description of that species and from his figure in F. 

 Ital. 728, in its concatenate, shorter conidia and branching 

 basidia. The specimen of V. gilva in Sydow's Mycotheca 

 Marchica differs from this in its much longer (500/i) brownish 

 hairs and rather narrower (1.5//) conidia and from the descrip- 

 tion in Sylloge Fung, in its longer hairs and shorter (6-8/.1) 

 conidia. 



Var. minor differs in its slenderer, smoother hairs and 

 smaller (5-6xl.25—1.5/i) conidia. — On dead Salix. 



Spoririesmium sorisporioides. — Forming thin, tobacco- 



brown, narrow, elongated, sublinear strips or patches, 2-5 cm. 

 or more long, evenly effused and composed of nearly globose 

 cells 12—15/2 diam. loosely combined into glomerules (conidia) 

 25-40// diam. almost exactly like the spore masses of Soros- 

 porium. — On decaying wood. Montana, June 1889. Ander- 

 son, no. 519. 



1 Macrosporiuni puccinioitles. (Plate VII, figs. 7-11.). — 



Tufts hysteriiform, narrow 7 , 2-3 mm. long, erumpent through 

 longitudinal cracks in the cortex of the stem so as to closely 

 resemble a Puccinia. Hyphae erect, simple, septate, yellow- 

 ish-hyaline, 60-70x5//, densely compacted, at first swollen at 

 the apex, then the swollen part becomes 1-septate and assumes 

 an elliptical or oval shape, 20—30x15-20//, and finally be- 

 comes elongated, oblong or clavate-oblong, 60— TO x 18-22//, 

 brown, 3-4-septate and muriform. The resemblance to 

 Puccinia is very striking. — On dead stems of Bigeloviae? with 

 Dothidea Montaniensis, E. & E. Helena, Montana, Nov. 

 1888. Rev. F. D. Kelsey. 



JEcidium Liatriclis. — Spermogonia small, epiphyllous, 

 black, on slightly thickened, light colored, sometimes purplish- 

 bordered, elongated spots, 0.5-1 cm. long by 8-4 mm. wide. 

 ^Ecidia hypophyllous, thickly scattered on the spots, the 

 pseudo-peridia narrow-cylindrical or slightly enlarged above,
