context easily separable from the cuticle, bright-yellow, becoming 

 buff with age, at first mild to the taste, but with a lingering un- 

 pleasantness ; lamellae free or adnexed, about i cm. wide to nar- 

 rower at the stipe, moderately crowded, pale-dull-yellow, edges 

 at first distinctly furfuraceous ; spores ellipsoid, smooth, rounded 

 at the ends, obliquely apiculate at the base, hyaline, uni-guttulate, 

 12 X 7m; stipe tapering upward, bulbous at the base, stuffed or 

 hollow, clothed with a very delicate, furfuraceous layer above the 

 annulus, nearly glabrous below, pale-dull-yellow, 7 to 12 cm. 

 long; annulus distinctly yellow, very delicate and loosely woven, 

 thin, usually adhering to the margin of the cup in an appendicu- 

 late way after rupture, and leaving but a slight, delicate ring on 

 the stipe ; volva very delicate and loosely woven, distinctly yellow, 

 sometimes pointed, but more often nearly flat at the base, soon 

 glabrous, becoming less distinct with the growth of the plant. 



Type collected in the township of Springfield, New Hampshire, 

 about September 1, 191 7. Known from several other localities 

 in New Hampshire, also.

Cultures of Puccinia Clematides (DC.) Lagerh. and Puc- 

 cinia Impatientis (Schw.) Arth. 



During 1917 and 1918 the baneberries, Actaea alba (L.) Mill, 

 and A. rubra (Ait.) Wild., which grew in a small wood near Ste. 

 Anne de Bellevue, P. Q., were heavily infected with aecia. Field 

 evidence suggested the connection of these aecia with Puccinia 

 Clematidis (DC.) Lagerh. on Hystrix patula Moench. Roots of 

 Actaea rubra were dug up in the fall and kept in a cool cellar 

 during the winter. When placed in a greenhouse in the spring, 

 they developed rapidly. Wintered telial material of Puccinia 

 Clematidis on Hystrix patula was tested and found visible. In- 

 oculations were made on three pots of Actaea rubra on April 

 28th. Aecia were first noticed on May 5 and a very heavy in- 

 fection developed. One pot of plants kept as a check remained 

 free from infection. The inoculations and observations con- 

 nected with these cultures were made by Mr. P. I. Bryce, of the 

 Biology Department of Macdonald College, who also made the
