indicating that H. Lloydit and H. alutacea were identical. Later, 
however, he states?? that PATOUILLARD believes H. Lloydii “is a good 
species and very different from H. alutacea.” Luoyp saw specimens 
of H. alutacea at the Herbarium of the Museum of Paris and said 
that he does not think it possible the two plants are the same. 
Through the courtesy of Dr. BrEsADoLA I have had the oppor- 
tunity of seeing the type specimen of Hypocrea Lloydii, and I con- 
sider it identical with H-ypocrea alutacea. In plate XVI are photo- 
micrographs of a section from the dried specimen through a portion 
of the clavula showing the perithecia, and in plate XV are similar 
photomicrographs of the plant collected at Ithaca, the material having ° 
been fixed while it was fresh. The only differences which can be 
observed are those which are due to the difference in the age of the 
plants at the time they were collected. The specimen of H. Lloydit 
Was quite mature, as shown by the more advanced stage of disappear- 
ance of asci or freedom of spores from the asci. The perithecia are 
therefore somewhat older and larger, and are thus crowded against 
each other, and flattened on the sides where they are closely packed. 
The form of the plants themselves at first sight appears different, 
H. Lloydii, plate XI V, fig. 3, being long and slender, while those of 
H. alutacea, plate XIV, fig. 1, are stouter. But the individuals of 
H. alutacea which were all growing close together differ more among 
themselves than the H. Lloydii does from the individual of H. 
alulacea at the left. It is unfortunate that this specimen is curved, 
and therefore that not all of the stem is shown in the photograph. 
However, the long stem of the single individual of H. Lloydii (the 
Species is based on the single specimen collected), as one can see 
from an examination of the photograph, is due to the fact that the 
lower half of it was in the leaf mold, the stroma having 1ts origin 
about 4°™ below the surface of the leaf mold. It is a matter of com- 
mon observation in the case of many stipitate fungi to find the stem 
“onsiderably elongated under such conditions. I have seen notable 
“xamples in the case of Collybia radicata, Clavaria ardenia, and 
Others, the length of the stem depending on the depth of the ie 
Gags below the surface. The plant is quite variable also in — 
Its stoutness. This is perhaps also due to some extent to co
