The plants have a strong rooting system that binds them firmly to the soil and 

 they do not become "tumblers." At the same time the interior structure is that 

 of a Bovista and the only objection to so calling them is, if included in the genus 

 Bovista it is not possible to clearly define the latter genus. 



BOVISTELLA DEALBATA (Plate 88). Peridium globose, 

 thin, opening- by a definite mouth, strongly attached to the soil, and not 

 breaking away (normally) when mature. Cortex a thin, furfuraceous 

 coat, which first breaks into areas, and then disappears leaving the sur- 

 face smooth. Sterile base none. Gleba olive brown. Capillitium of 

 separate, deeply colored, branching threads. Spores globose, smooth, 

 4-5 mic..f with slender pedicels, 10-12 inic. 



This plant is only known to occur on the Pacific coast. It has a 

 general close resemblance to Bovista plumbea but different habits and 

 a different cortex. It was compiled in Saccardo as Bovista dealbata, 

 but I do not believe the compiler has any clear ideas as to the distinction 

 between Bovista and Bovistella.

BOVISTELLA BOVISTOIDES (Plate 70). Peridium flaccid, 

 dark brown, globose, thin, opening by a definite mouth, attached t<> the 

 soil and not breaking away when mature. Cortex a thin, furfuraceous 

 coat which breaks into areas and is subpersistent. Sterile base none. 

 Gleba dark, brown. Capillitium of separate, deeply colored, branching 

 threads. Spores globose, smooth, 4-5 mic. with slender pedicels, 10- 

 12 mic. 



Originally described from India % I have received it from corre- 

 spondents both from British India and Australia. It is very close to 

 the preceding species, and the descriptions read very much the same. 

 On comparison, however, they are quite different. This species has 

 much thinner, more flaccid peridium, darker in color and a different 

 colored gleba.

BOVISTELLA HENNINGSI1 (Plate 89). Plant subglobose, devoid of a 

 sterile base. Peridium papyraceous-cartilaginous. Cortex minute, fasciculate, 

 persistent spines. Gleba olive-lead color. Capillitium separate, deeply colored, 

 thicker walled threads with thick (12-16 mic.) stem and relatively short, strongly 

 tapering, pointed branches. Spores globose, smooth, 4-5 mic. with thin pedicels. 



All that I know of this species is a plant from Mussooree, British India, 

 which I found at Berlin, labeled "Bovista plumbea, form." and half of which was 

 given to me by Dr. Hennings. I feel sure it should not be referred to B..vi>ta
