LYCOPERDACEAE 67 



exclude C. crelacca, as its basidia have not been studied. Our material does not show 

 them.

Canadian Arctic. Bernard Harbor. Johansen, coll. (Dearness Herb, and U. N. C. Herb.) Spores 



distinctly warted, 4.2-6.5m- Capillitium threads up to 1 l/i thick. 

 Swedish Lapland. Abisco. Coker, coll. (U. N. C. Herb.). One of these two collections had spores 



very minutely warted, less so than in the other, apiculate, spherical to subsphcrical, 4.5-6ju. 



Capillitium threads up to 7.5m thick. 



Calvatia craniformis (Schw.) Fr. 



Lycoperdon delicatum B. & C. (Not L. delicatum Berk.) 

 L. Missouriense Trelease 



Plates 39 and 112 



Plant large, up to 9 cm. thick, obovoid or top-shaped, the thick, stalk-like base 

 rounded below and attached by fibrous strands; cortex very thin, papery, smooth, 

 nearly glabrous to delicately furfuraceous, pale tan or grayish in color, at maturity 

 scaling off in areas; inner peridium also thin and fragile, yellowish to reddish, the upper 

 part cracking into plates and scaling off after the cortex peels. Subgleba occupying 

 the stalk-like base, of honeycomb structure and quite spongy, concave above and long 

 persistent. Gleba white, then greenish yellow or soiled ochraceous in color. 



Spores (of No. 538) spherical, smooth, with a distinct mucro or short pedicel, 

 2.8-3.9/z thick. Capillitium slightly branched, sparingly septate, walls with numerous 

 pits, possibly holes in them which are 1-3^ in diameter, easily breaking up, usually at 

 these pits; average thickness of main threads 3.5ju. 



Unlike C. cyathiformis, this species inhabits wooded places or shrubby borders of 

 paths or walls, and is much less abundant, though not at all rare. It, too, is a palatable 

 and valued food. It is easily distinguished by the greenish yellow rather than purple 

 spore mass. The type in the Schweinitz Herbarium is a fine example of the species. 

 The spores are smooth, 3.2-3.6/* thick. 



In referring to C. craniformis on p. 100, Hollos is confused. The L. delicatum 

 that Lloyd says is the same as C. craniformis is evidently from the context the delicatum 

 of Berkeley and Curtis from Pennsylvania, not of Berkeley from India, etc. (L. Berkeleyi 

 De Toni). In his reference to L. delicatum on p. 153 of Myc. Notes, Lloyd makes the 

 double error of confusing Morgan's treatment of what he took to be L. delicatum Berk, 

 with the B. & C. species and further of accusing Morgan of having no conception of 

 L. delicatum B. & C, when Morgan stated thirteen years earlier (Journ. Cin. Soc. of 

 Nat. Hist. 12: 171. 1890) the same thing that Lloyd here announces in italics, i.e., 

 that L. delicatum B. & C. is the same as C. craniformis. It seems well established that 

 L. Missouriense Trelease (see Sacc. Syll. 9: p. 277) is also the same as C. craniformis, 

 (Morgan, 1. a). For explanation of Cooke's mistake in thinking it C. lilacina see 

 Lloyd, Myc. Notes, p. 308.
