Plants sessile or short stipitate, cupulate or urceolate, 2-4 
cm. diam.; hymenium creamy-white when fresh becoming brown 
on drying; cup clothed externally with rufous brown hairs which 
are obtuse, up to 4-5-septate, scarcely constricted at the septa, 
rather thin walled, up to 350/4 long, rarely longer; stem when 
present stout, more or less longitudinally plicate and sometimes 
lacunose below. Asci clavate-cylindrical, apex rounded, 300- 
325x15/4; spores uniseriate, hyaline, continuous, granular-rough- 
ened, elliptical to elliptical-oblong, 25-33x10-12^ (majority 28- 
32/x) ; paraphyses cylindrical, apex slightly thickened, septate, 
brown. 
On rich woodland soil, burnt soil, or much decayed wood, 
Aug.-Oct. Pennsylvania and Delaware. 
I have not seen this species in the fresh state and so can give 
no more information about it than can be gotten from herbarium 
material. It seems to agree in size, form, color, and certainly in 
the structure of the excipulum, with M. fusicarpa , the chief dif¬ 
ferences being found in the somewhat longer external hairs, and 
the shape and size of the spores. The latter are relatively much 
broader being elliptical or oblong-elliptical with rounded ends, 
rather than fusiform, and average 28-32/x long as against 36-41/4 
in M. fusicarpa. The largest spores of M. semitosta barely sur¬ 
pass the smallest ones of M. fusicarpa. 
Dr. Michener’s collections seem to be somewhat immature, 
but Mr. Ellis’s material seems to be better developed. The spores 
present agree perfectly in all the specimens. In the type of M. 
semitosta they measure 25-33x10-12^, while in that of P. hainesii 
they are 30-31x10-12/4.

W. A. KELLERMAN. 
Symbiosis in the Genus Lolium, E. M. Freeman, Minn. 
Bot. Studies, 3:329-334, Oct. 18, 1904, admits that it cannot be 
affirmed without reservation that the entire life-history of L. 
temulentum is understood, but it can be affirmed that the yearly 
life-cycle is known, and that the parasite can live on indefinitely,
