In some specimens the perforation or umbilicus at the apex of the 

 pileus is rather large, with a broad margin, giving a truncate ap- 

 pearance such as is ascribed to the species ; b'lt in many specimens 

 the apex is more rounded or obtuse, and would not be regarded as 

 truncate. The apical perforation, which in other species communicates 

 with the interior of the stem, in this one is closed, at least in recently 

 developed specimens, although specimens are sometimes found in 

 which the closing membrane has disappeared and the pileus is clearly 

 perforate. This membrane, however, when present, is so depressed or 

 sunk below the surface that it is liable to be overlooked. It makes 

 the pileus umbilicate rather than perforate. Possibly it was this pe- 

 culiarity of structure that led Rev. C. Kalchbrenner in his paper on 

 New or Little-known Phalloidei, p. i6, to place this species with the 

 Cynophalli.^ Whether this and the other peculiarities of structure 

 already pointed out warrant the separation of this species from the 

 other Hymenophalli or not I leave for other mycologists to decide. 

 1 he noticeable characters of this species may be grouped together 



Bulb ovate, pinkish, sometimes marked by a few irregular, elevated 

 lines or wrinkles, after rupturing slightly split on the margin ; pileus 

 conical or ovate-conical, at first covered, except at the apex, by the 

 ohve-green spore-stratum, minutely cellular-spongy, umbilicate at the 

 apex, whitish when denuded ; stem cellular-spongy, hollow, subcyl- 

 indrical, tapering upwards within the pileus and surrounded at the top 

 by a short, entire, pendent membraneous veil, also tapering down- 

 wards withm the bulb and surrounded at the base by a similar cup- 

 shaped veil, whitish; spores narrowly elliptical, .00016'— 0002' of 

 an inch long, about half as broad.

 covered by Mr. Ravenel in 1846, but appears to have remained un- 

 published till 1873.
