In addition Melanogaster mollis which I named (page 1047) 
from Wyoming is, tests Mattirolo, Melanogaster variegatus overly ripe. 
In Schweinitz‘s herbarium is a specimen from Europe of Melanogaster 
variegatus labeled ’’Rhizopogon aestivus", 
MELANOGASTER AMBIGUUS (Pig. 2005).- This to the eye is very 
much the same as Melanogaster variegatus but the spores (Fig. 2007-B ) 
are of a different shape and much larger (8-12 X 16-20) and easily 
distinguish it. It is fairly common both in Europe and the States. 
Specimens, New York, Pennington: Washington, Piper: Australis, 
Guilfoyle. I have no European material, 
MELANOGASTER RUBESCENS (Pig. 2006 ).- A very rare species in 
Europe, it appears to me the dried specimens have much broader cell 
walls than either of the preceding, hence the cells are more distinct. 
The spores (Fig. 2007-C) are narrow, elliptical, 4 X 12, very pale 
color, and closer to the spores of the usual Rhizopogon than to the 
other Melanogasters. I have only one collection from Mattirolo, 
Italy. 
The foregoing three species are the only three known in the 
flesh to either Mattirolo or Tulasne and apparently the only three 
valid species that exist. We do not, of course, include the foreign 
species that Messrs. Zeller and Dodge and ourselves have recently 
published as Rhizopogon, but we suspect that several of them are 
better classed as Melanogaster. 
Berkeley found the two most frequent species in England and 
named Melanogaster variegatus as Melanogaster Broomeianus and ambiguus 
as a variety f intermedius. Melanogaster Berkeleianus is, teste 
Berkeley ipse, Rhizopogon rubescens, Melanogaster aureus, Melano¬ 
gaster sarcomelas and Melanogaster ©doratissimus proposed by Yittadini 
(as Octavinia ) about ninety years ago, have not been found by a 
single reliable individual since. Hesse does record the latter as 
rare and Harkness claims to have found two in California. No reliance 
can be placed on either record. 
Corda proposed Melanogaster tuberiformis which he claims is 
common in Bohemia, and has spores shape of tadpoles. No one but Corda 
ever saw a Melanogaster with such spores and no one but Hesse and 
Harkness ever claimed since to have found the species. Harkness 
"confirmed" Corda’s statement or rather cites the figure where the 
spores are shown shape of tadpoles. A man must have a lot of cred¬ 
ulity to believe such improbable stories even if put forth as 
"science". 
Harkness discovered a "new species", Melanogaster Eisenii in 
California with globose spores but the chances are that what he had 
was; a young Scleroderma. No one who has a knowledge of the subject 
would have the temerity to propose a Melanogaster with globose spores. 
Bose claims to have found "en tres grande abondance" not far 
from Charleston, S. C. a curious fungus half puff ball, half truffle 
with black foetid powder filling the lacunose cells of the gleba. 
He figured it and called it Uperhiza caroliniensis (teste De Toni) 
but as a matter of fact it was Sprengle who added the "caroliniensis". 
De Toni compiled it and put it in Melanogaster with a question mark. 
It is quite doubtful, especially as no one in this country in the one 
hundred and ten years that have since intervened ever found anything 
that at all suggests it.
