In older ones each of these is divided into two equal parts, and the 
inferior one is usually elongated slightly. But many asci which were 
dried at this stage show sixteen segments in a crowded chain, all of 
about the same form, and subglobose to subcuboidal. In a very 
few cases the spore is pyriform, divided into two cells by a cross wall 
cutting off the lower smaller cell without any perceptible constriction 
at the septum. It will be seen that the age of the asci and spores at 
the time of collection of the plant will vary, and consequently there 
will be a variation in the form of the spore segments. All may be 
subcuboidal and of the same size and form, or when older the inferior 
segment may be slightly elongated and narrowed, and the superior 
one will be globose to subcuboidal. They are so crowded also in 
the ascus that there is a tendency for them to cling into a chain 
or necklace, and this may be aided not only by a small amount of 
periplasm, but also by remains of the disintegrating ascus which are 
difficult to perceive. 
If Karsten’s plant had not been reported as growing on an insect, 
one would have no hesitancy in placing it in Hypocrea alutacea, for 
all the characters of form, color, and structure agree. The only 
difference is that of the substratum. The fact that it is reported as 
growing on a decaying insect, taken in connection with its agreement 
in form, structure, and color with Hy pocrea alutacea, is rather strong 
evidence that this is only a further extension of the range of decaying 
organic matter on which the fungus grows. It should also be noted 
that Podostroma leucopus was found in coniferous woods, and Hy po- 
crea alutacea is usually found under pines or spruces, though it occurs 
on decaying wood of the broad-leaved trees, as is seen from its Saal 
rence on Alnus cited above, and ELxis3° reports it at Newfield, N. J 
on “bark of a decaying (maple ?) limb, lying on the ground.”4°
