The description of this species leaves us in the dark 

 concerning the manner in which the peridium ruptures, 

 nor does the single imperfect specimen which I have seen 

 throw any light on this point. If the peridium opens by 

 a small apical aperture the species seems too near L. molle. 

 If it ruptures irregularly it will be separable from L. sac- 

 catum, so far as the description goes, only by the sraooth 

 spores and the accurately limited capillitium. From 

 L. ccelatum its smaller size and smoother peridium would 

 apparently be its distinguishing features. 



Schweinitz in his Synopsis of the Fungi of Carolina and 

 Synopsis of North American Fungi reports some species not 

 yet mentioned but as I have had no opportunity of con- 

 sulting his specimens nothing positive can be affirmed con 

 cerning them. 



L. Bovista in Syn. Car. Fung, he says varies with a purplish 

 colored dust, from which it is probable that he includes 

 under this name both X. cyatkiforme and L. ccelaium. L. 

 umhrinum I suspect maybe equal to L. gemmatum\diT. hirtum 

 as a synonym of which it is given in Smith's English Flora 

 L. perlatum he refers in his Syn. N. A. Fung, to L. maxi- 

 mum^ which in turn is given by Fries as a synonym of L. 

 giganteum. His L. candidum he afterwards referred to L. 

 areolatum, another probable synonym of L. ccelatum. L. 

 pratense, according to Fries, is synonymous with L.pusiUurn^ 

 and L. excipuliforrne, as already stated, is regarded as a 

 variety of L. gemmatum. There then remains only L. 

 quercinum and L. uiriforme of his lists which may possibly 

 be unlike anything already noticed but about which there 

 is so much uncertainty that not even a conjectural 

 reference would be of any value.
