27. Cryptosporium falcatum sp. nov. 
Acervuli 40-260 ju,, gregarious in irregular patches, 2-6 cm. 
across, erumpent in minute pustules, noticeable on account of the 
white masses of ejected spores. Conidia hyaline, falcate, nucleate, 
20-35 X 6-8 ft., mostly about 30 X 7 
On bark of the trunks of unhealthy or dead Abies balsamea 
(L.) Mill., near London, Ontario, April-May, 1915, /. Dearness

28. Ramularia Lapsanae (Desm.) Sacc. 
Oidium fusisporioides f. Lapsanae Desm. 
Collected on Lapsana communis L. at Flora, Ont., July, 1915, 
J. Dearness 38^ The indefinite arescent areas caused by the 
fungus are indistinguishable from the discolorations produced by 
the red spider, Tetranychus telariiis. This may account for the 
fact that this fungus has not hitherto been recorded here. 
29. Stemphylium nemopanthes sp. nov. 
Hyphae usually shorter than the conidia, hyaline, branched, 
4.-3 ft thick, making with the conidia black, gregarious tufts, 100- 
200/1. Conidia irregularly pyriform, acrogenous on the hyphae 
and branches, 30-35 X 20-24 ft, made up of dark-brown shining 
cells 3-4/1, not separating.
