' The similarity in the appearance of C. /utescens and C. cinnabar- 
znum has led to the confusion which has existed concerning 
their distinctions. Schweinitz in 1822 described a form from 
Carolina as M. lutescens and later in 1831 a second species as M. 
cinnabarinum. Sprengel (1827), Fries (1849), and Nees, 
Henry, and Bail (1837) all give M. /utescens as the only Ameri- 
can species, but Corda, as we have just seen, gives also Calostoma 
cinnabarinum, without being aware of its generic connection with 
Mitremyces lutescens. Massee in his monograph states that owing 
to the considerable variations in size, color and form which 
C. cinnabarinum presents he is of the opinion that the Mitremyces 
lutescens of Schweinitz is but a young condition of his MW. ctmna- 
barinum, and unites the two under this name. The only refer- 
ence made to the shape of the spores of M. dutescens by the early 
observers is found in the description of Corda, who states that 
they are globose. Calostoma cinnabarinum, on the other hand, 
as is well known, has ellipsoid punctate spores. Among the 
specimens contained in the Curtis collection and labeled . 
lutescens are two examples, however, one from Alabama (coll. 
Peters), the other from West Virginia (coll. A. H. Curtiss), which 
agree with Corda’s description in possessing globose spores. 
They further differ from C. cinnabarinum in having a longer foot- 
stalk, the gelatinous strands of which are finer and more closely 
woven, while the color is of a more uniform pale yellowish. The 
length of the footstalk (fig. 7) was as much as 9™, although 
part of it had evidently been broken off at the ai and in a 
fresh state it might have been even longer. 
These two dried specimens were the only material of C. 
lutescens which I was able to examine, but they indicate that 
Massee was in error in considering the species identical with C. 
cinnabarinum, and that, while it is probably the globose spored 
form to which Schweinitz gave the name of M. Jutescens, it is, 
_ with little doubt, the form which Corda describes by that name. 
The “M. lutescens” from Ceylon described by Massee as C. 
Berkeleyi is identical with the American form as far as concerns _ 
the character and measurements of the spores. The habit,
