or leaf mold to very rotten wood and to wood in a one-fourth to a one- 
half decayed condition. This range would be represented by a habitat 
life curve, which rises from the leaf or wood mold in the ground 
to the upper limit on the decaying wood, influenced, to some extent 
at least, by other conditions of environment. Or if the wood habitat 
is the normal one, then the curve would descend according to con- 
ditions to the wood mold and leaf mold in the ground. This range 
in habitat is manifested by a large number of the higher fungi. The 
curve rises or descends from the normal habitat according to the 
peculiarities of each species and according to the modifying influences 
of other environmental conditions. 
The history of Hypocrea alutacea has become more interesting 
by the publication of Hypocrea Lloydii Bresadola in 1902, which 
was collected by C. G. Luoyp in West Virginia, in the summer of 
rgor. Following the brief description, BRESADOLA notes*® that the 
species is very interesting, with the aspect of Cordyceps but fructi- 
fication of Hypocrea. The photograph published at the time, with 
the description, suggested to me that the plant might be identical 
with Hypocrea alutacea, and I inquired of Mr. Lioyp if he did not 
think this to be the case. My letter was communicated to Dr. 
BRESADOLA, and his reply was published in a note by Mr. LioyD”’ 
in September 1902. These notes from BRESADOLA are very inter- 
esting. In the first place he was not familiar with H ypocrea alutacea, 
since he had never seen the plant; but accepting, as was nature 
under the circumstances, TULASNE’s interpretation of its parasite 
nature, the plant communicated to him by Mr. LLoyd was believed 
to be a new species in the section Podocrea of SACCARDO,”® a section 
formed to include species of Hypocrea with a vertical stroma. BRESA’ 
DOLA also compared the structure of the stroma of H. Lloydit with 
the structure of both Clavaria ligula and S pathularia flavida, and 
finds it very different from either. He concludes by saying that if 
Hypocrea Lloydit is really identical with H ypocrea alutacea, 4 species 
unknown to him, then he does not believe in the parasitic nature of 
the latter. At this time Luoyn (/. c.) accepted BRESADOLA’S nole ”
