:^88 THE RUSTS OF NOVA SCoTIA. — FRASER. 



Arthur ill the ''North American Flora" places this species 

 in the genu- Kudineola on account of the absence of the aecia. 



Phragmidium speciosum Fr, 



Earlia speciosa (Fr.) Arth. 



0. Pycnia mostly hypophvllous, in i^-roiips opposite aecia. 



T. Aecia livjiophyllou-, petiolicolous or caulicolous, some- 

 times epiphyllous, often developing on the fruit, solitary or in 

 irregular groups, small or occupying considerable areas, up to 

 1 cm. long on the stem, orange; paraphyses mostly oblong or 

 ("lavate, usually 8-15 by 40-50/*. Aeciospores globose, sub- 

 globose or ellipsoid, 20-25 by 22-35ju; wall pale yellowish, 

 verrucose, contents orange. 



II. Uredinia wanting. 



III. Telia caulicolous or especially fruiticolou:^, jiroiluc- 

 ing swellings on st^em and pedicels, large, sometimes 2x1 cm. 

 compact, black. Teliospores cylindrical, sometimes somewhat 

 ellipsoid, 29-33 by 60-11 5m, usually rounded below, slightly 

 narrowed above, cells 3-9, apex with snb-liyaline papilla; wall 

 brown to black, about 4fi thick ; ] edicel hyaline or tinted above, 

 very long, 8-10 times the length of the s])ore or longer, not 

 swelling in water. 



On Rofsa (species not determined). Pictou. 



This rust is very commnn on the wild roses about Pictou. 

 It attacks especially the pedicels and the fruit, the affected 

 fruit remaining green and not changing to the normal red 

 colour. 



It occurs upon any and all s]iecies of roses and is widely 

 distrihut^^d in the United States and riuiada, Arthur places 

 this species in the genus Earlia, as it differs from the true 

 members of the genus Phragmidium in the gelatinous j^edicels 

 of the teliospores, the large compact telia on the stems and 

 the absence of uredinia.
