BOVISTELLA RADICATA (Plate 87). The European form of this plant 

 is hardly worthy of a separate name. It is a more rigid plant, and has stiffer 

 cortex spines and not so strong pedicels to the spores which is all the diflfnvnce 

 I can note. Originally collected in Algeria by Durieu, it was called Lycoperdod 

 radicatum by Montagne. Recently it has been collected in Tunis by Patouillard, 

 and the name changed to Bovistella radicata. In Europe it is a very rare plant 

 and only two collections are known, both made during the past season i 1905] 

 and sent to me. First, by Rev. P. Merino, Galicia, Spain; second by 1'mf. 

 Plottner, Rathenow, Germany.

A FORM FROM JAPAN. We have received from K. Miyabe a specimen 

 collected at Sapporo by J. Hanzawa, which is we think a form of BoviMrlla 

 Ohiensis. The specimen is old and little more than a sterile base and hence we 

 are not sure as to its cortex. It has the appearance, however, of being an old 

 specimen of Bovistella Ohiensis, the same structure and threads. The >porcs 

 are slightly different from the American plant, being perfectly globose, slightly 

 larger. 5-6 mic, and with pedicels so thin they are seen with difficulty. 



BOVISTELLA LYCOPERDOIDES (Plate 87). IVridium sub- 

 globose with a stem-like sterile base. Cortex white, of small, tufu-d. 

 soft spines. Gleba dark umber. Capillitium short, separate threads. 

 Spores smooth, 5-6 mic., with slender pedicels. This plant is related 

 closely to the preceding but differs in shape, cortex, habitat and u'.eba 

 color. Only one collection is known, made at Xilvala, X. W. India, 

 by O. W. Duthrie, and preserved at Kew. These specimens grew in 

 moss. The plant was called by Cooke Mycenastrum lycoperdoides a.nd 

 is compiled in Saccardo as Scleroderma lycoperdoides. 



BOVISTELLA PALUDOSA (Plate 87). Periditim reddish 

 brown, subglobose, contracted to a short stem-like base, thin, becoming 

 smooth when old. Cortex minute, sub-furfuraceous. Sterile l>a-e 

 scanty.f Gleba dark olive. Capillitium of separate, branched threads. 

 with the main stem thick. 8-10 mic., and deeply colored. Spores glo- 

 bose, smooth, 4-5 mic., with slender pedicels, 10-12 mic. long. 



This plant grows in Sphagnum moss and is quite similar t<> the 

 preceding. It has a different cortex and color. But one collection K] 

 known, made by Leveille at Malesherbes, France, in 1845. Two spec*] 

 mens of this collection are in the Museum of Paris and one at Ke^ 

 It was called by Leveille Bovista paludosa and compiled in Saccardo 41 

 Calvatia paludosa. It has no relation whatever to the genus Calvatia. 



with Vi C ?LA 0t i b if sure il has a slerile bas as specimens are not cut open. However, al 

 nis shape I have ever seen do have sterile bases.
