stipitate, the stipitate portion cylindric, hollow, reticulate-pitted, 
white below, orange-colored above, slightly enlarged upward, di- 
viding into three arms ; arms arched outward, united at the apex, 
transversely wrinkled, cylindric or sometimes compressed so as 
to appear triquetrous, orange-colored, attenuate upward, 3-6 cm. 
long; gleba dark-green, borne on the inner side of the arms, 
foetid ; spores hyaline, ellipsoid-ovoid, 4. 5-5. 5 X 2-2.5. 
Growing in the yard of Mrs. F. F. Schellenberg, Pittsburgh, Pa., 
July, 1915. Type specimens have been deposited in the Carnegie 
Museum, Pittsburgh, Pa., and in the New York Botanical Garden. 
Plants developed from eggs removed from the ground had very 
long arms, but the stipitate portion of the receptaculum was very 
short. The description of Coins javanicus Penzig agrees in a 
general way with my plants. The former are smaller. I do not 
have access to the original description, and Saccardo in the Sylloge 
does not give the color of C. javanicus, so I have not been able to 
compare the two species with respect to color.

Review of Kniep’s Beitrage zur Kenntnis der Hymeno- 
MYCETEN, IIP 
Kniep in his previous reporP on the question of the origin of the 
binucleated cells in the Basidiomycetes mentioned the appearance 
of small bodies in the clamp connections which appeared to him 
to be disintegrating nuclei. In his present paper he makes these 
indefinite bodies the basis of a new theory in explanation of how 
the binucleated cells in the Basidiomycetes arise. In accordance 
with his new view, he accepts the fact that the binucleated cells 
arise before the anlage of the carpophore is formed. While his 
previous observations are correct, he now interprets them as ab- 
normalities. The present article deals with a cytological study 
of Corticium varians sp. nov. and Corticium serum Pers. These 
species have a single nucleated spore and the nucleus divides after 
the spore germinates. A young mycelial cell has but a single 
nucleus but at the time a clamp connection is formed the nucleus
