THE RUSTS OK NOVA SCOTIA. FRASER. 



376 



II. Uredinia epiphyllous, scattered or in lines, oblong, or 

 linear, ochraeeous-brown, pulverulent, surrounded by the 

 ruptured epidermis. Urediniospores mostly globose, 19-24/*; 

 wall yellowish-brown, thick, about 2^, finely and densely 

 yerrucose. 



III. Telia mostly epiphyllous, sometimes hypophyllou* 

 scattered, often confluent, abundant, rounded oblong or linear, 

 often 1 cm. or more in length, pulvinate, dark brown or black. 

 Teliospores globose, subglobose, obovate or elliptical, 13-22 by 

 19-40/u; wall dark brown, smooth, thickened at the apex; 

 pedicel hyaline, much longer than spore ; a few two-celled spores 

 present. 



Pycnia and aecia on Atriplex patula L., A. patula Var. 

 hastala (L.) Gray, Pictou,' May 21, 1910. (Chenopodium 

 album L., shown by cultures, not collected). 



Uredinia and telia on Distichlis spicata (L.) Greene. 

 The life history of this rust was made out by the writer by 

 cultures during the spring of 1910 (Mycologia 3: 72-74. 1911). 



Sowings of the teliospores were 

 were successful on Chenopodium 

 album and Atriplex patula Var. 

 hasiata. Collections of aecia were 

 made on Salicornia europea L. and 

 Suedia maritima which probably 

 also belong to this rust. They were 

 collected beside the rusted Distichlis 

 and were morphological 1 y similar ta 

 the aecia on Atriplex. 



Infection experiments by Arthur 

 (Jour. Mycol. 1:234. 1909) showed 

 that Puccinm subnitens Diet, on Distichlis spicata has 

 aecia on Chenopodium, Atriplex and other plants. The aecia 

 of both rusts are similar and cannot be separated easily. These 

 facts suggest the possibility that the rusts were once identical 



Uromyces Peckianus. Four telios- 

 pores, two urediniospores.
