68 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



gitudinally septate; spores hyaline, even, flattened on one side, 



9X5V2M- 



A specimen of Tremellodendron Hibbardi, fig. 106, collected 



by Miss Hibbard at West Roxbury, Mass. — the type locality 

 agrees well with the original specimen of Clavaria tenax, fig. 105. 

 T. tenax has somewhat the aspect of some forms of T. pallidum 

 but is readily separable from the latter by the very dark hymen- 

 ium of T. tenax.

"C. caespitosa carnosa, clavis difformibus compressis contortis 

 substriatis maximis albo-testaceis. 



"Septembri et Octobri. Caespites ad radices arborum et in 



terra efformat magnitudine capitis humani, fungus omnino ab- 

 normis, quibusdam annis frequens, aliis rarissimus. Ex una 

 radice, subradiculosa oriuntur clavae interdum regulares, ad sex 

 uncias latae, unam vel tres uncias altae et unciam crassae; sub- 

 stantia carnosa et fibrosa agaricina, odore muscoso Agarici 

 Prunuli. Interdum clavae solitariae occurrunt. Quandoque 

 pulvere albo detergibili tegitur." 



Present-day collections of this fungus would not be referred 

 to the Clavariaceae, for very careful examination of preparations 

 of the outer surface of the fructifications of the authentic spe- 

 cimens does not show basidia nor any distinctive spores or 

 fruiting organs by which the fungus may be classified. I did 



not find any evidence that these pyriform masses are Agarics 

 overrun by a Hypomyces. European mycologists have found in 

 Europe malformations of Lentinus tigrinus of such form that 

 they so regard "Clavaria gigantea." In the Eastern United 

 States Clitopilus abortivus may form in great abundance mal- 

 formations very similar in aspect and consistency to the spe- 

 cimens of "Clavaria gigantea" which have been preserved; it is 

 my opinion that the latter was based on such abortive growths. 

 The note by Schweinitz of odor of Agaricus [Clitopilus] prunulus 

 favors this conclusion also.
