It will be noticed from the above stations that the plant reaches 

 us rarely from the South or West. 



FORMS OF LVCOPERDON ATROPURPUREUM. 



The plant is most puzzling, varying not only in size of spores and color of 

 g^leba according to conditions of ripeness, but very much as to shape and size. 

 The usual form (unmarked in above list) is obovate or subglobose (Plate oo 

 1%. oo), one half to an inch and a half in diameter. 



A more robust, large, subglobose form (as shown on our plate oo fig. oo of 

 Lycoperdon delicatumt) we have indicated in above list with a t. 



A pear shaped form, tapering to the base, with a somewhat slender stem we 

 indicate with a $. 



A lange, turbinate form such as is shown on our plate oo fig. oo we indicate 

 with a II. 



A rare, subcylindrical form with a small head we indicate with a double 

 star (I). This corresponds with the original Lycoperdon tlongatum (type at 

 Kew). We have received but one specimen, from Minn. Bot. Survey. 



The following forms based on cortex variations we would dis- 

 tinguish by a separate name though it is often difficult to refer plants 

 by this character. 



LYCOPERDON STELLARE*( Plate 57). This form has spines 

 not so slender as the typical form but thick at the base. As shown in 

 our figure (7 enlarged) the extreme form appears quite different from 

 the usual, slender-spined form (fig. OO enlarged). It is the form of 

 atropurpureum with the most strongly developed spines, and we have 

 never seen it typically from Europe. 



REFERENCES : This form in Peck's paper is Lycoperdon atrcpurpureum var. 

 stellare. It is Lycoperdon hirtum of Morgan's paper,t but this form does not 

 seem to occur in Europe and Lycoperdon hirtum (of Persoon at least), I take 

 to be the typical form of Vittadini's atropurpureum.

LYCOPERDON UMBRINUM (Plates 43 and 58). This plant 

 has all the interior characters described under Lycoperdon atropur- 

 pureum, including the slow change of the gleba and the various colors 



t According to specimens he gave me, but spines "long and slender" do not apply 

 well to it.
