posed portions, the gill-like structure is not very pronounced, but 

 in other specimens the gill-like structure of the gleba is very 

 plainly to be seen. It is always more or less apparent in longi- 

 tudinal sections as may be seen on comparing figures 5 and 6 on 

 Plate 107. In some cases the anastomosing plates seem much like 

 those of a Favolus. altliough it i-^ difficult to make certain of any 

 regularity such as occurs usually in specie^ of that genus. The 

 polyporoid and agaricoid resemblances arc, however, more strik- 

 ing than hymenogastroid. The chambering, nevertheless, is 

 sufficiently complete to range this species in the Hymenogastrineae 

 rather than in any other group of equal rank. 



In appearance and structure, this species varies so much from 

 5. Guienzii, the type of the genus that it may well be doubted 

 whether it will ultimately be considered cogeneric with it, but, at 

 present, it seems best to refer to Secotium rather than attempt 

 to split up that genus. Its nearest relatives are 5^. coaractum 

 Berkeley and S. Gnnnii Berkeley. It resembles very closely the 

 figures of Berkeley (Hooker's Journal of Botany, 1845) and of 

 Corda (Icones Fungorum, pt. I, pi. 6, f. 25-30), but differs from 

 them in the shape of the pileus (or peridium) and in the shape 

 and size of the spores. From 5". Gnnnii Berkeley as described 

 by IMassee (Grevillea, vol. 19, p. 96. 1891 ), it difi:ers in tb.e slender 

 sterigmata and in the shape and size of the spores. Lloyd (The 

 Lycoperdaceae of Australia, New Zealand and Neighboring 

 Islands, p. 7, pi. 26, f. 7 and 8) figures a plant from Texas, under 

 the name of S. coarctaium, which may belong to this species. It 

 agrees reasonably well in habit, but the spores appear to be more 

 globular than in our plants. I am indebted to Dr. Ed. Fischer of 

 Bern, for examining material and giving me the benefit of his 

 opinion concerning the position of this plant.

This species, unlike the preceding, is not at all plentiful in 

 the region about Berkeley, where it has been foimd thus far, only, 

 and occurs in small numbers usually more or less buried in the 

 soil and covered by a thick layer of leaves. W.hen the leaves are
