becomes recurved after splitting longitudinally and acquiring a stellate 

 aspect, and Batarrea (Pers.), which possesses an axile column immedi- 

 ately beneath the middle of the inner peridium. It develops into a stout 

 stalk, which raises the closed inner peridium on its summit and ruptures 

 the outer one, which now resembles in appearance the velum universale 

 of Hymenomycetes. In Scleroderma (Pers.) the development of the 

 glebe is intermediate between Hymenogastreae and Lycoperdaceae. 

 While the trama is disorganised, and a portion persists as a fine network 

 together with the masses of spores, it yet forms no true capillitium.

other sections, are yet readily comparable with them. The chambers 

 of the glebe possess very stout walls, and ultimately become separated 

 from each other. The wall of the peridium becomes transformed into 

 a gelatinous substance over the apical region, and on its disappearance 

 the chambers of the glebe (peridiola) are left exposed in the interior of 

 the bowl-shaped lower portion of the wall. Free and detached they 

 resemble comparatively large sporanges. In Crucibulum (Tul.) a thin 

 white membrane ternied the epiphragm temporarily covers the summit

The PHALLOIDE^: are an assemblage of very remarkable and strange 

 forms, in which the Basidiomycetes find their highest development.
