JOHNSTON. — ON CAULOGLOSSUM TRANSVERSARIUM. 69 



synonyms Herculea Fries and Schtveinitzia Grev. is a synonym of 

 Podaxon. Cionium Lk., the only other generic name that has been 

 applied to it, represents a plant of an entirely different character, un- 

 doubtedly referable to the Myxomycetes. In view of these facts it seems 

 necessary to propose a new generic name for this form. 



In order to determine whether species other than C. transversarium 

 should be similarly treated, it seems desirable in this connection to 

 examine the published data which are available concerning Cauloglos- 

 sum elatum Fr., C. aegijptiacum (Mont.) Zobel, and C. novo-zelandi- 

 cum (Henn.) Fischer, which appear to be the only forms, with the 

 exception of the two species of Podaxon and the Penis caninus vir- 

 ginianus Plukenet already mentioned, that have ever been referred to 

 Cauloglossum. 



Cauloglossum elatum, a form occurring in East India, is described by 

 Fries (10) as possibly synonymous with Clavaria pistillaris Lour. (19). 

 In general form and in the presence of an axil columella it resembles 

 C. transversarium. In the minor characters, its white color, small 

 size (only half an inch in height), it seems to differ distinctly, while the 

 fact that the peridium falls away, only scaly remnants being left at the 

 base and apex, separate it clearly from C. transversarium, and suggests 

 that it belongs rather in the Podaxaceae. 



Cauloglossitm aegyptiacum (Mont.) Zobel, which was originally de- 

 scribed under Podaxon by Montague (22), is figured and described in 

 Corda (29). Zobel, however, modified Greville's original generic 

 description of Cauloglossum by adding the following points : "basidiis (?) 

 stellato glomeratis ; . . . stipes firmus, erectus, basi rudimentis volvae 

 vestitus. Volva incompleta, cum stipite connata, coriacea." A species 

 to which such characters apply cannot be included in the same genus 

 with C. transversarium ; and it seems probable that Montague was 

 right in placing it in Podaxon. It is a form that has been reported but 

 once, by M. Bove, from the lands between Suez and Gaza. 



The last form that has been placed under Cauloglossum is Clavo- 

 gaster novo-zelandicum described by P. Hennings (15) and referred 

 to Cauloglossum by Fischer. Clavogaster was a new genus pro- 

 posed by Hennings for a New Zealand form, the characters of which he 

 described as follows: " Perithelium subcoriaceum, persistens e stratis 

 binis discoloribus efformatum, clavatum, stipitatum. Capillitium sub- 

 fasciatum in cellulas favosas, polyedras, sporis levibus, ellipsoideis, color- 

 atis, pedicellatis. Hippoperdo peraffinis." 



In view of the fact that the presence of a capillitium and the absencf
