it is possible that the exoperidium may under certain conditions carry 
away with it more of the intermediate red layer than usual." 
The description of the footstalk as “ reddish brown ” is again quite 
true of dried specimens, but in the fresh plant, when the strands are 
swollen with moisture, the color is a pale watery yellowish or greenish 
yellow. 
In old plants gathered after a rain on November 21, 1898, the 
footstalks were 7-8 cm. long, and 3% to 4% cm. wide at the thickest 
part, narrowing abruptly below the peridium and at the dark, some- 
what root-like base. The strands were rarely less than 2 mm. in 
diameter (except just below the peridium) and often 4-5 mm. 'They 
were much branched and anastomosed. After drying (in hot air) the 
footstalks shrank to the following dimensions: length 412-5 cm., width 
114-2 cm., diameter of strands 12-3 mm. ; and the color changed to a 
dull red brown. A comparison of these figures is interesting in con- 
nection with the description of the next species about which little 
seems to be known in a fresh state. 
The spores, important for the identification of the species, are 
elliptic-oblong, echinulate or punctate, pale yellow, 17-22 x 8-9 p (18x 
8-10 p, Burnap). The plant occurs (about Boston) from July to 
November. 
Calostoma lutescens (Schwein.) Burnap. Burnap’s notes on this 
species were based on two specimens in the Curtis Herbarium. Two 
specimens, collected in November, 1898, by the Rev. Paul Whitehead, 
near Richmond, Va., furnish a few additional notes. 
The general color of the whole plant (dry) is a pale greenish 
yellow. About the base of the endoperidium is a stiff collar, rather 
imperfect but still conspicuous, formed of spreading, somewhat revo- 
lute, irregular teeth, basal fragments of the exoperidium which re- 
main attached. Some indication of this collar may be seen in Burnap’s 
drawing (pl. xix, fig. 1), but he makes no mention of it. If it should 
be found to be characteristic it would offer another means of distin- 
guishing this from the last species, for it seems to indicate that the 
exoperidium here splits from above, instead of from below. The foot- 
: Desvaux (Jour. de Bot. 2: pp. 94-95, quoted by Massee in his monograph on 
the genus Ann. Bot. 2: 5, p. 38) remarks as follows: “This plant sometimes loses its 
color, when it has been dried carelessly, because its color, which is only superficial 
and does not penetrate the substance of the outer layer of the peridium, consists of 
a sort of red pruinosity that easily comes off."
