JOURNAL OF MYCOLOGY. 



[Vol. 1, 



RcESTSLiA LACERATA, Tul. — On Gratoegus tomeniosa. JSTear Ottawa, 

 August. Possibly these speciineiis are referable to H. cornuta, Tul. 

 Some of them are certainly distinguishable with difficulty from that 

 species. 



^ciDiuM CoMPOSiTARUM, Mart.— On leaves of Aster Idndleyanus, 

 JS'ipogon river, July. Another form (of this species V) on Lactuca Cana- 

 densis from the same locality has the secidia densely clustered in patches 

 i cm. in diameter. 



^ciDiUM Grossulari^, DC— Lake Ellen, Nipigon river, June. 



^ciDiUM Ranunculacearum, DC— On Anemone nemorosa, Nipi- 

 gon river, July. This is the form distributed in K. A. F. 1003 a. 



^ciDiUM ALBUM, Clinton —On Vicia Americana, Nipigon river, July. 



^ci^iUM Caladit, Schw. — On Ariscema triphyllum, Ottawa, June. 



^ciDiUM YiOL^, Schum.— On V. renifoUa, Ottawa, June. 



CoLEOSPORroM MmiATUM (Pers.)— On Bosa Uanda, Red Rock, Lake 

 Superior, June. 



Melampsora salicina, Lev. (Uredo.)— On willow leaves, Lake 

 Nipigon, July. 



Uredo obtusa, Strauss.— On Potentilla gracilis, Moose Jaw, N. W. 

 Terr., May. 



Uredo gyrosa, Reb.— On leaves of Bubus.

C^OMA LUMiNATUM, Schw.— On Bubus trijiorus, Ottawa, June. 



UsTiLAGO URCEOLORUM, Tul.— Fruit of Carex siccata and C. canes- 

 cens, Lake Nipigon, June. 



IMPERFECT FU^^GI. 



ExciPULA CONGLUTINATA, E. & E. (in Bull. Wash. Coll. no. 1, p. 6.) 

 Dead stems of Banunculus, Cape Chudleigh. The specimens are in no 

 way distinguishable from the original Mt. Paddo specimens. 



Ephelis borealis, E. & E — Stroma of a grayish bufC color and of 

 fine grumous texture, extending along and enveloping the leaf for about 

 i cm., after the manner of Epichloe typhina, Fr. Spores masses not 

 numerous (2—5 on a stroma), innate, causing convex swellings which are 

 at first covered by the superficial layer of the stroma but are at length 

 exposed with an imperfect margin, appearing somewhat like a flat Peziza. 

 Spores acicular, nearly straight or often bent in the middle, hyaline or 

 pale yellowish, nucleolate (?), ends subobtuse, 15—25 x f z^. 



On leaves of living grasses, Nova Scotia, June, 1883. Possibly this 

 may not prove sufficiently distinct from E. Mexicana, Fr., but that spe- 

 cies is said to have a black stroma and infests the inflorescence of grasses. 

 LYCOPERDINE^. 



Lycoperdon atropurpureum, Vitt.— Ottawa. 



Secotium Warneri, Pk.— Among rubbish in gardens, Ottawa. 



Mycenastrum Oregonense, E. & E., Ottawa. 



The following species of Lycoperdon apparently undescribed was
