This species occurred last year abundantly at Chudleigh, and 
appears to be certainly the same with the species of Tulasne. 
Hysteromyces graveolens , Vitt., of which authentic specimens 
have been kindly communicated, is probably also the same 
species, as is also the case with Rhizopogon luteolus and R. 
virens from Italy, Hymenangium virens , Kl., Rhizopogon 
luteolus , Corda, and perhaps with Rhizopogon luteolus , Fr. 
This species- grows gregariously in sandy fir-woods. When 
young it is almost transparent, and resembles young Phallus 
caninus , being of a pure white, and furnished with white roots 
which proceed from a mycelium which spreads sometimes an 
inch or two ; in this state it turns pink on being touched ; 
in a more advanced stage it is yellow, but even then it has 
here and there a pink tinge. The smell is very much like 
that of Melanogaster ambiguus when old, but when young it 
has an acid smell like that of sour ham. It rapidly decays 
into a brown fetid pulpy mass. (B. and Br., 1 . c.). 
Rhizopogon luteolus, Tul. (Fig. 9). Globose, or oblong- 
ovate, from whitish becoming dirty yellow, then olive-brown, 
clothed with numerous slender, free or adnate mycelium 
strands, peridium thick, subcoriaceous, cells minute, rounded, 
subequal, at first empty, becoming stuffed, septa whitish,
