meter those on which they are seated. When arrived at their 

 full growth they are somewhat obovate and produce four spi- 

 cules which at length are surmounted each with a globose 

 spore. When the spores are fully developed the sporophores 

 wither, and if a solution of iodine be applied, which changes 

 the spores to a rich brown, they w^ill be seen still adhering by 

 their spicules to the faded sporophores. The spores soon be- 

 come free, but the spicule often still adheres to them as 

 figured by Dr. Greville, f Sc. Crypt. Fl/ t. 336, but they are 

 not attached to the intermingled filaments. In Bovist a plum- 

 bed the spores have very long peduncles. I regret that I have 

 not been able to meet with a specimen in a fit stage of growth 

 to show them adhering to their sporophores. Up to the time 

 when the sporophores have nearly arrived at their full growth, 

 the structure is essentially the same as in Lye. giganteum, as 

 will be seen from the subjoined figures. 



Young specimens of Geastrum show the same anastomosing 

 cavities as Ly coper don and Bovista; I have not however at 

 present been able to meet with a specimen sufficiently young 

 to show the development of the spores. The only species 

 which occurs abundantly in this neighbourhood is G. Bryantii, 

 and in this species the fruit-bearing cells are already withered 

 in extremely small specimens long before the volva is rup- 

 tured. 



I regret not to have had an opportunity of examining Scle- 

 roderma and Elaphomyces in a sufficiently early stage of 

 grow r th, but as M. Klotzsch has demonstrated the existence 

 of true subterranean Hymenomycetes it is probable that they 

 will be found to agree in structure. With respect to Batarrea 

 Tulostoma, Cauloglossum and Podaxon, they are so evidently 

 allied to Ly coper don that there can be no doubt that they 

 also are Hymenomycetes. Polysaccum according to Corda has 

 spores furnished w T ith an hilum, and seated upon short distinct 

 cells springing from the floeci. It is probably therefore an 

 ally of Ly coper don. This however, and the genera not named 

 above, referred to Trichogastres, require due examination. 



I now come to the consideration of the genus Phallus, and 

 I have here to regret that my observations are confined to 

 Phallus caninus f but as far as that goes the proof is satisfac-
