SOME NEW SPECIES OF RUSSULA 



Gertrude S. Burlingham 

 (With Plate 7 and i Text-figure) 



Most of the following species have been under observation for 

 several years, and with the possible exception of R. simulans and 

 R. ornaticeps they seem to be rare. Even these species are lim- 

 ited in season and in habitat. The first collection of R. Hib- 

 bardae was made in 1916 by Miss Ann Hibbard who also col- 

 lected the type of R. viridi-oculata. She has made numerous 

 water-color sketches of the species described from Vermont and 

 has placed these at the disposal of Miss Eaton for the preparation 

 of the plate which accompanies this article. 



On July 29, 1919, I found several specimens of R. disparilis 

 Burl, growing on Newfane Hill, Vermont, under yellow and 

 white birches and poplars. This had previously been reported 

 only from the type locality, Stow, Mass. The taste at first was 

 sweet' and nutty, then tardily peppery. The stipe in some speci- 

 mens had a pink wash near the apex and base on one side. The 

 lamellae in mature specimens were pale maize-yellow. 



Russula simulans sp. no v. 



Pileus fleshy, broadly convex, becoming infundibuliform with 

 age, up to 11 cm. broad; surface reseda-green to ivy-green, paler 

 on the margin, vinous-purple in the center, or slate-violet and 

 green streaked together, or the whole faded with some yellowish 

 spots, viscid when wet, cuticle separable half way to the center, 

 striate-reticulate under the lens and very slightly so to the naked 

 eye, glabrous; margin even or scarcely striate-tuberculate for a 

 depth of about one mm., inrolled nearly to maturity; context
