Key to the Species 



Odor strong and offensive; cavities small G. graveolens 



Odor not offensive; cavities large G. morchelliformis 



Gautieria graveolens Vitt. 



We copy the following description from Zeller and Dodge: 



"Fructifications globose, 1-2 cm. in diameter, light ochraceous-buff to Prout's 

 brown; stipe slender and fragile, up to 1 cm. long, 1 mm. thick; columella frequently 

 reaching the center of the fructification, forking; odor very strong, suggestive of decay- 

 ing onions; peridium thin, composed of delicate, thin- walled, loosely woven hyphae, 

 soon rupturing and disappearing; gleba ochraceous-tawny to cinnamon-brown; cavities 

 globose or elongated, minute, empty; septa 40-80/z thick, composed of small hyphae, 

 compact; cystidia clavate to subfusiform, hyaline, often obscured by the spores; paraph- 

 yses linear, septate; basidia broadly clavate, 2-spored, 12-16 x 8-9/i, with long filiform 

 sterigmata; spores ochraceous-tawny, usually with 10 prominent striations, the latter 

 smooth or nearly so, apex rounded, base pedicellate, 18-19 x 11-12/z, often with a large 

 oil globule."

Gautieria morchelliformis Vitt. 



We copy the following description from Zeller and Dodge: 



"Fructifications globose to oblong, 1-3 cm. in diameter, with a basal stalk-like 

 rhizomorph, usually much branched; columella rudimentary, merely a subglobose 

 summit of the rhizomorph; peridium thin in early stages, quickly evanescent; gleba 

 ochraceous-tawny to hazel; cavities 1-6 mm. in diameter, subglobose to irregular; 

 septa white when broken, hyaline to cream-colored under the microscope, composed of a 

 stupose mat of hyphae, about 75/z broad; basidia about as large as the spores, hyaline, 

 granular, 2-3-spored; sterigmata filiform, as long as the spores; cystidia in the upper 

 cavities of the fructification, not prominent; paraphyses clavate, septate, hyaline; 

 spores fusiform to citriform, ochraceous, longitudinally striate, with 8-10 usually 

 smooth striations, 1-2-guttulate, pedicellate, 12-24 x 8-12.5//."
