of T. hrumale Pers. from North Carolina, and in 1834* he gives 

 two species, T. bruniale and T. sqiiaumlosiim,\ of which latter he 

 writes "not a variety of the preceding but closely resembling 

 Rinella of Rafinesque,:}; " but notwithstanding his assertion to the 

 contrary T. squamosum is now commonly regarded as a variety of 

 T. pedimculatum {brumalc). In 1837, Montagne§ described T. 

 cxaspcmhim from Cuba, collected by Ramon de la Sagra, the 

 well-known Cuban naturalist, and this species has since been re- 

 ported from India. In 1867 Curtis'!! mentions T. fimbriatum and 

 T. mamtnosum as " common in North Carolina," and six years 

 later Berkeley** reported T. fimbriatum, T. mammosum, and 

 T. Meyenianum, collected by Wright in New Mexico. As late 

 as 1 89 1, Masseeft published Berkeley's description of T. WrigJitii, 

 also from New Mexico. Other American species have been de- 

 scribed since, T. obcsum C. & E., %% T. punctatum Peck, §§ and T. 

 semisulcatum Peck. *^ Much of the western material found in the 

 Ellis collection had been referred to T. obesum, although it repre- 

 sents very diverse forms. T. punctatiim has been reported from 

 several localities, but of T. semisulcatum only the type specimens 

 are known, and these are inaccessible at Albany, if indeed they 

 are still in existence. Extensive collections have been made in 

 different parts of the United States in the past few years and we

t Since writing the above it has been possible to examine Schweinitz' original 

 specimens, which are carefully preserved in the Philadelphia Academy of Natural 

 Sciences. There is a question as to the specimen marked T. brtanale being T. pedtin- 

 culatnm, to which it is usually referred, owing to the color of the peridium, which is a 

 bright terra-cotta red, unlike anything seen before — but this may be due to the color of 

 the clay in which the plant grew or to other causes of unknown origin. The specimen 

 marked T. squamosum resembles greatly some of our specimens of T. fimbriatum in 

 general habit and spore characters, with the exception of the mouth which is entire, but 

 not tubular and prominent, like the mouth of T. pedtinadahtm — which fact may be 

 owing to the wasting of the cartilaginous tissues occasioned by time — so that it is hardly 

 possible to determine what this plant really was.
