continues attached round the base of the stipe. In Ph. impudicus the inner wall of 
the peridium is also rent at its apex, and the gleba is detached from it and rises 
clear above it. An annular transverse rent in the lower portion of the cone separates 
the cup-shaped basal portion which remains round the base of the stipe from the upper 
portion, which is torn into shreds, and the pileus which bears the gleba is thus 
separated from the stipe except at its upper margin which adheres firmly to the 
summit of the stipe. 
The gleba when exposed to the air drops from its stalk as a slimy mass containing 
the spores in consequence of the deliquescence of its gelatinous tissue. In Phallus 
caninus the cone and the part of the inner wall of the peridium which covers the 
gleba go through this process of disorganisation and become indistinguishable before 
deliquescence. For further particulars and differences among the species the reader is 
referred to the more elaborate works which will be cited below, and the descriptions in 
systematic treatises.

Clathrus cancellatus, as we have known since Micheli’s time, agrees with Phallus in 
the character of the gleba and peridium. But the receptaculum which raises the 
gleba from out of the peridium has the form of a net or lattice-work with large 
meshes surrounding the outer surface of the gleba. We know from Tulasne' especially 
that the development of the parts begins here, as in Phallus, with a separation 
of the uniform tissue of the young compound sporophore into central column, 
gelatinous layer, and outer wall of the peridium (Fig. 155). Lamelliform processes 
which anastomose and form a net-work pass from the peridium to the surface of 
the central column, passing like septa through the gelatinous layer. The lowest of 
these converge towards the point of insertion of the column or of the whole body 
and unite there. Then the column becomes further differentiated into the inner 
wall of the peridium, the gleba, and a roundish axile gelatinous body of a cartilaginous 
consistence. The latter occupies the entire central portion; its base rests on the 
peridium and passes into it, the whole of its surface, with the exception of the point 
of insertion, being covered by the thick gleba. The lamellae of the trama in the 
gleba spring on all sides from the central body; hence it appears in a transverse
