as found in collections. It is distinguished from atropurpureum (typ- 

 ical) by its reduced cortex spines. Many specimens occur however, 

 that are difficult to refer to either species (see plate 58 fig. 3). Be- 

 sides L. atropurpureum has a bad habit of losing its large spines when 

 it gets old and retaining its small ones so that it is often impossible to 

 decide to which form old specimens belong. In the small-spined form 

 (umbrinum) there are two types of spines. The usual type is of a 

 furfuraceous, granular nature (Plate 58 fig. i). Another form has 

 the small spines more regularly fasciculate and persistent (Plate 58 

 iig. 2). The latter is the type of spines we find in fuscum and cupri- 

 cum and it is only possible to refer such specimens to these two species 

 on the general color of the plant. Nor is it possible to split umbrinum 

 along these lines for sometimes we find both types of spines on the same 

 specimen. In shape and size the plant varies from little, pear shaped 

 specimens not a half inch in diameter (Plate 58 fig. 4) to large, tur- 

 binate plants such as is shown on plate 58 fig. 7. Lycoperdon elegans* 

 (Plate 58 fig. 10) is a large, robust, globose form. Lycoperdon deli- 

 catum* (Plate 44 fig. 8) is a smaller globose form. At first, though 

 it does not seem possible, they are the same species but specimens of 

 all intermediate forms and sizes are so common that it is not practicable 

 to distinguish them at all. In the following list we have marked with a 

 dagger (f) specimens tending to the large, turbinate form. 



REFERENCES : This plant appears as Lycoperdon glabellum in all the Amer- 

 ican papers also as Lycoperdon elegans in Morgan's paper. The same plant (cfr. 

 Myc. Notes, p. 209) is common in Europe and we, of course, take the earlier 

 European name for it.

LYCOPERDON FLOCCOSUM* (Plate 59). -We note a form 

 with same internal characters and the same coat of small, furfuraceous 

 spines as Lycoperdon umbrinum, but which has a few large, soft, white, 

 rlocculent spines superficially over the inner coat. (Plate 59 fig. i). 

 It seems to me closest to umbrinum but it is analagous to velatum if 

 the veil were reduced to a few, scattered, soft, flocculent spines.
