On Adoxa moschatellina. 

 March to May. 



Biology. — The mycelium of this fungus is perennial ; affected 

 plants, cultivated by Professor Trail at Aberdeen, and by myself at 

 King's Lynn, year after year, produced only teleutospores. Mr. 

 Soppitt placed some over-wintered teleutospores in active germination 

 on healthy plants, in March, 1888 ; in ten days the teleutospores had 

 reproduced themselves without the intervention of either uredospores or 

 zecidiospores. He had previously satisfied himself of the distinctness 

 of this species from P. albescens by his observations of the fungi as 

 they occurred in a state of nature in Yorkshire. 



Puccinia saxifragae. Schlecht. 



Teleutospores — Sori amphigenous, dark chestnut or blackish brown, 

 on numerous discoloured spots, irregular, soon pulverulent, 

 confluent. Spores elliptical or ovate, slightly constricted, 

 apex surmounted with a conical or wart-like pale papilla, 

 faintly reticulate, yellow-brown, 26-45 ^ i4-2o/x. Pedicels 

 short, deciduous.
