 middle west." 



177. Calvatia gigantea Batsch. 



This species is found infrequently in pastures in various parts of 

 western Oregon. A specimen from Multnomah County, collected in Sep- 

 tember, weighed 6 lbs. 7 oz. and measured 28 x 23 x 18 cm.

 November. Frequent. Nos. 1964, 2010, 2026. 



Lloyd has called our western form var. occidentalis. It differs in 

 being smaller and having less development of the sterile base.

 I believe this is the first report of this species from the northwest.

The peridium in our plants is glabrous, sometimes cracked, warm buff 

 or darker, sometimes buckthorn-brown, becoming light ochraceous-salmon 

 to russet where bruised, reaching 12 cm. broad and 5 cm. high, about y 3 

 emergent. Odor at first farinaceous, then disagreeable. Gleba a dark 

 livid-brown just under the peridium and a warm blackish-brown or black 

 near the center and base. Spores livid-brown to deep livid-brown under 

 scope, spherical, sharply echinulate, 8-13 /n, according to maturity. 



181. Scleroderma hypogaeum sp. nov. 



Fructifications subglobose to irregular, firm but pithy when young, 

 deliquescent with age, 1-7 cm. in diameter, color light buff to pale ochra-

 ginning to deliquesce. Surface glabrous or of innate-appressed fibrils. 

 Mycelium of white rhizomorphs attached to the somewhat downward pro- 

 jecting sterile base. Peridium reaching 3 mm. thick, compact, hyaline; 

 gleba at first white, then yellowish, turning purplish-umber at maturity 

 (drying black where cut) ; tramal septa white, variable in thickness, of 

 parallel, hyaline hyphae, gelatinizing and deliquescing at maturity ; fer- 

 tile cells at first filled with a hyaline, basidia-bearing capillitium, later 

 filled with spores and remnants of capillitium ; basidia hyaline, pyriform
