COCCOMYCES RUBICOLA, E. & D. 



Ascomata covered by the adnate epidermis, hemispheric-prominent; the pus- 

 tules pierced in the centre, then radiate-cleft and open, exposing the pale, whitish 

 or wood-coloured disk, i— i mm. in diam., bordered by the toothed margin of the 

 ruptured ascoma. Asci, oblong-cylindrical, sessile, 60—70 x 7 //. Paraphyses, 

 filiform, curved or bent at the tips. Sporidia fasciculate, linear, nucleate, hyaline, 

 sub-attenuated below, 45 — 60x2 — 2^//. 



On dead stems of Ricbus strigosus, Granton, Ont., Aug., 1895. Herb. D., 

 No. 2352. 



C. Rnbi (Fr.) is a foliicolous species, having sporidia only 6—8 /i. long. 



HYPHOMYCETES. 

 Rhinotrichum herbicolum, E. & D. 



Effused, light yellow, becoming brown in the centre. Hyphae, coarse, septate, 

 branched, nearly hyaline, 8—10 /i, thick. Fertile hyphas, sub-undulate above, tips 

 swollen and bearing the globose, sub-hyaline, finely echinulate, 7 — 9 fi., conidia. 



On dead stems of Solidago Canadensis, London, Can., Aug. 1895. Herb. D., 

 No. 2314. 



This species differs from R. Curtisir, Berk., in its coarser hyphae and its smaller 



echinulate conidia. 



Stysanus tubericola, E. & D. 



Stem composed of parallel fibres, 700 to 800//. high, 10 — 12 /i thick, tips of the 

 fibres relaxed and bearing the elliptical, brownish, 4 — 5 x 2^ — 3 ^ conidia, forming a 

 terminal oblong head no — 130 x 35—50 //. The fibres forming the stem spread out 

 at the base forming a loosely interwoven grayish mycelium. 



This fungus developed on pieces of potato in a moist chamber which had been 



used for culture purposes. Other pieces of potato were inoculated with it and thus a 



considerable quantity was obtained. London, Can., Apr: to June, 1894. Herb. D., 



No. 2261. 



Ramularia Aris^m^e, E. & D. 



Spots oval, tan coloured, turning pale or yellow-white by concentric rings from the 

 centre outwardly, i to 2 cm. Conidial tufts minute, very numerous, mostly epiphyl- 

 lous, giving a grayish cast to the pallid area of the leaf, the tuft consisting of a few 

 close, almost sessile, conidia. Conidia hyaline, grumous, nucleate, straight, 

 20 — 22 x 3 — 3i II. 



On leaves of Ariscema triphyllum, Torr., Granton, Ont., July 1893. Herb. D., 



No. 2139. 



ToRULA Caricina, E. & D. 



Hypophyllous forming dense dark olive, orbicular or elliptical patches, i — 2 mm. 

 diam., composed of erect, simple or branched from the base, chains of closely con- 

 nected, smooth, translucent, pale brown conidia, 20 — 30 // long, consisting of 10 to 

 15 conidia about 3 /^ in diameter. 



On dead leaves of Carex Itipulinns var — ; London, Can., Sept. 1896. Herb. D., 

 No. 2403. 



T. graminis, Desm., also occurring on species of Carex, has conidia 5 to 6 /y in 

 diam., becoming black. 



Cladosporium (?) myriosporum, E. & D. 



The fungus first appears as pale specks on the pea-pod ; it soon becomes erum- 

 pent in small, light-coloured tufts, and finally confluent, forming a sc'urfy or faveolate 

 scabby coat on the pod. From the first the much-branched, fertile hyphae produce
