North American Fungi. it 



heij^ht. A beautiful species, regular in form, soft to the touch 

 and attractive in color. 



9. L. ELONGATUM, Berk. Peridium globose above, con- 

 tracted below into a stout thick base, more or less elongated 

 and cylindric or tapering downward; m^xelium composed of 

 thick fibers. Cortex a loose flocculose white or yellowish 

 coat, drying up into a mealy or furfuraceous persistent layer, 

 which scarcely reveals the pale shining surface of the inner 

 peridium. vSubgleba occupying more than half the interior 

 of the peridium ; mass of spores and capillitium pale oliva- 

 ceous, then pale brown or finally purplish ; the threads much 

 branched, the main stem much thicker than the spores, the 

 branches tapering ; spores globose, distinctly warted, 5.5-6.5 

 mic. in diameter. 



Growing on the ground in damp woods. Ohio, Morgayi. 

 Peridium 1-2 inches in diameter and 2-3 inches in height, 

 the base Y^-x inch in thickness. In form it somewhat re- 

 sembles L. geniDiatiim, but it has a cortex like that of L. 

 glabclhun. Perhaps Trelease's Figure 2, Plate IX, is referable 

 to this species. 



10. ly. ELEGANS, Morg. n. sp. Peridium large, depressed 

 globose, plicate underneath and sometimes with a narrow 

 umboniform base, which is continuous with the thick root. 

 Cortex at first flocculose, white or yellowish, drying up into a 

 dense furfuraceous persistent coat, which becomes ochraceous 

 or brownish in color, and sometimes obscurely areolate. Sub- 

 gleba broad, convex above, occupying a third part or more of 

 the peridium; mass of spores and capillitium, olivaceous, then 

 pale-brown or finally purplish-brown ; the threads much 

 branched, the main stem thicker than the spores, the branches 

 long and tapering; spores globose, distinctly warted, 5-6 mic. 

 in diameter. Plate I, Fig. 4. 



Growing on rich soil on the open prairie about Iowa City, 

 Iowa, Prof. T. H. McBridc. Peridium i>^-3 inches in diam- 

 eter. In form and size this species somewhat resembles 

 Calvatia fragilis, but the threads are arranged in two sets as 

 in lyycoperdon ; the cortex is similar to that of L. glabelhim ; 

 the mycelium forms a remarkably thick root.
