76 THE GASTEROMYCETES OF THE UNITED STATES AND CANADA 



715. On D -. WagstaS's lawn, September 8, 1913. 

 811. In old road to Rocky Ridge Farm, September 10, 1913. 



7059. On wet ground in deciduous woods in Emerson's swamp, August 5, 1923. Spores dull brown 

 under the microscope, spherical, warted, 5.8-7.2m thick, often with a very long pedicel, up to 3 

 times the length of the spore. Capillitium threads 3.5^.8^ thick, pitted. 

 7160. On lawn among elms, September 27, 1923. Smallest plants about 1 cm. broad. Spores 



distinctly warted and with hyaline material, 5.5-7^, often with a long pedicel. 

 7165. On ground in swamp of Emerson Farm, September 28, 1923. Largest plants up to 5 cm. wide.

Lycoperdon subvelatum Lloyd 



Plates 41 and 112 



Plant depressed-globose, 3 cm. broad and about 1.5 cm. thick in the dried state; 

 base pinched to a short stalk, ending in a stout cord which in our one collection branches 

 under ground to bear two fruit bodies; cortex thick, superficially areolated into appres- 

 sed, spongy patches on a granulated membrane, the whole peeling back from the top 

 in strips, some of which have fallen off. The inner peridium is glabrous, shining, light 

 grayish brown, without the scales which form the conspicuous furfurescence on the 

 denuded inner peridium of L. marginatum. Mature gleba deep brownish purple; 

 subgleba nearly white, occupying only the stalk, the chambers obvious. 



Spores (of No. 7263) distinctly warted, 4.8-6// thick, furnished (in the dry state) 

 with long pedicels up to three times the diameter of the spores, but these pedicels fall 

 off when put into water. Capillitium threads irregular in size, wavy, encrusted in 

 places, up to 6.5/i thick. 



This agrees in every respect with Lloyd's species (Myc. Notes, pp. 224 and 274). 

 It differs from L. rimidaium in the thick, continuous cortex which peels off in pliable 

 patches and strips. This peeling off in good sized patches recalls L. marginatum, but 

 the resemblance between the two is entirely superficial. We have four collections of 

 typical rimulatum from the same section of Florida, which is good evidence that the 

 present plant is not merely a regional form of that species.

Lycoperdon umbrinum Pers. 

 L. hirtum Mart. 

 L. glabellum Peck 



Plates 48 and 113 



Plants depressed-globose with an abrupt base or pear-shaped with a tapering base; 

 up to 3.5 cm. broad and 4.5 cm. high, usually about 3 cm. high; white or light brownish 

 gray before maturity, turning to tawny buff or brownish buff or light grayish tan, or 

 rarely golden yellow. Surface lightly covered with a fine scurfy or granular stuff mingled 

 with minute, slender spines that are separate and erect or, especially on the lower half, 

 flattened toward each other in patches. These spines are often absent in places. This 

 superficial material is very persistent and is only partly worn away in old age to show 

 the shining inner peridium. Subgleba occupying the stalk-like or tapering base and 

 extending in a thin layer up to the widest part of the plant, with chambers of moderate
