cave belevv, black, warty. Peridium scarcely at all intruded, at- 

 tached by copious brown flocci at the base. Fructifying stratum 

 white. Asci linear, containing eight elliptic warty s])oridia. 



I have but a single specimen of this species, which differs es- 

 sentially from G. verrucosa in its elliptic sporidia. It differs also 

 from G. papulosa, Vitt., in being black, not brown ; but this dif- 

 ference is less essential, and might vanish on the discovery of a 

 series of specimens. The peridium also is minutely warty, exactly 

 as in Genea sphcerica, Tub, and G. verrucosa (at least Klotzsch's 

 plant), whereas Vittadini describes his species as papillose in con- 

 trachstinction to verrucose. The species is possibly new, but I 

 have not sufficient materials to warrant me in proposing it as 

 such. 



I have another species from the same locality differing in its 

 black flesh and intruded peridium, which I cannot refer with any 

 probability to a recorded species ; but of this also I have only a 

 single imperfect specimen. Young unexpanded specimens of 

 Peziza rhizopus with their tufted rooting fibres bear a strong 

 resemblance to a Genea.

Distinguished from the foregoing by its floccose peridium, 

 which is rather soft and dirty white, and is so much intmded as 

 sometimes to leave no cavity. One specimen exceeds half an inch 

 in diameter and has no central cavity. The sporidia are globose, 

 at first smooth, at length verrucose. With age they lose their 

 transparency. The smell is very strong and disagreeable, re- 

 sembling that of Melanogaster ambiguus. A small slice of it 

 placed in a drop of water on the field of the microscope produced 

 when dry a quantity of fine radiating crystals.
