Dearness: North American Fungi 361 



Septogloeum salicinum (Peck) Sacc. 

 (Gloeosporium Peck). On Salix sericea. 

 Supplementary to the description in Ann. Rep. N. Y. State 



Mus. 33 : 26. 1883. 



The indefinite, "arid," spore-producing parts seem to develop 

 from precedent, dull-purplish areas. Acervuli hypophyllous, 

 irregularly rupturing the cuticle and delivering the spores in 

 yellowish heaps rather than in cirrhi. Sporules grumous, or 

 granular, no nucleate ones observed, 10-50 X 3-6/* mostly about 

 45X5/*, continuous or 1.3 septate, mostly 1 -septate, the prox- 

 imal half rounded on the end, 4-6 jx thick, the other half acu- 

 minate to a subacute point and curved. 



Septogloeum maculans Hark, on Salix lasiolepis. 

 Jour. Myc. 1 : 117. This is quite distinct and seems to be the 

 conidia of a dark, radiating fungus in the interior of the leaf. 



42. Cryptosporium candidum nom. nov. 

 A species of Cryptosporium on Abies was published in Myco- 

 logia 8: 107 under the preoccupied name C. falcatum. It is 

 hereby changed to C. candidum. The name refers to the white 

 flecks of exuded spore-masses on the dark bark of the host which 

 draw attention to the presence and location of the fungus. 



43. Fusoma rubricosa Dearn. & Barth. sp. nov. 



Minute, brown, elongate spots, 1 X .2 mm. indicate the points 

 of infection of the host; red areas extending from these spots 

 become confluent and impart their color to the leaf. Both sides 

 are similarly reddened but the lower side is white-specked with 

 the flake-like colonies of conidia. Conidia hypophyllous, hyaline, 

 shuttle-shaped, 3 septate, 35-45X11-15/*, subsessile or borne 

 on short sporophores, 9-18 X 4-5 /*•

 tional Park, Mont., Aug., 191 5, E. T. Bartholomew. Type col- 

 lection, Fungi Columb. 5019. 



44. Ramularia Clematidis Dearn. & Barth. sp. nov. 



Spots pallid, irregular, mostly bounded by the veinlets, paler 

 when held to the light than the unaffected portions of the leaf, 

 slightly reddened on the under side by the conidia. Hyphae 

 short, on colorless, flattish bases. Conidia hyaline, having a red- 

 dish tint in the mass, continuous or 1 -septate, 20-30 X 4-7 /*•
