Old walls and sandy pastures. Common about London It varies 



with a smooth and nearly solid stem, or subsquamose with a central 

 pith. A vertical section of the plant shows a groove round the top 

 of the stem, exactly as in Geasfer Brynntii {■a. character scarcely 

 sufficiently indicated in the figures of Greville and Sowerby and more 

 strongly marked in Tul. Jimbriatum) and a cavity towards the top of 

 the peridium, in consequence of the flocci being shorter above. The 

 stem is nearly of the same texture as that o( Battarrea phalloidcs, and 

 though the volva is so very imperfect even in the most highly developed 

 species, I cannot but think there is a strong affinity. Sporidia bright 

 ferruginous.
