From its nearest allies it is distinguished by its brilliant golden yellow 

 or ferruginous tint, its neat form, its firm equal stem, which is at first 

 coloured like the cap, and then acquires a rufous tint, but especially by its 

 being marked with little dots, but not reticulate, above the fugacious ring, 

 which is at first whitish, and then acquires a yellow tinge, and its decurrent, 

 minute, simple, golden yellow pores, inclining to sulphur. The flesh, more- 

 over, is of a decided, though pale yellow.— J/. /. B.
