GEOPYXIS. 379 



6-8 (a thick, passing into parenchyma at the cortex, cells 

 polygonal, 14-20 /x diameter; asci cylindrical, apex rather 

 truncate, narrowed below into a long pedicel, 8-spored; 

 spores obliquely 1 -seriate, hyaline, 1-2-guttulate, elliptical, 

 ends obtuse, verrucose, 16-18x10-11 //,; paraphyses septate, 

 slightly clavate.

On the ground in gardens, fir-woods, &c. 



The present species appears to have first been confounded 

 with the true Geopyxis radiculata by Cooke, in Grevillea, 

 vol. iii., fig. 92, which is called Peziza radiculata, Sow., and 

 and figured with rough spores. The present species is again 

 figured by Cooke in Mycographia, fig. 99, as P. radiculata, 

 Sow., and we get the description of Sowerby's fungus as 

 given by Berkeley in Engl. Flora, t. 5. p. 192, with the 

 additional statement that the spores are asperate. This last- 

 named description, with a little trimming up, is given by 

 Phillips in Brit. Disc, p. 203 ; finally, Phillip's description is 

 copied by Saccardo, Syll., viii. n. 629. 



The present species is at once distinguished from G. 

 radiculata by the ochraceous hymenium, and the larger, 

 verrucose spores. 



Cooke's specimens figured in "Grevillea" and "Myco- 

 graphia" examined. 



Var. Percevalii, Phil., Brit. Disc, p. 203. 

 Differing in the ascophore being notched to the base on 

 one side, as in the genus Otidea ; disc bright ochraceous. 

 On the ground. 



Geopyxis radiculata. Mass. 

 Usually more or less tufted, stipitate, at first globose and 

 closed, then expanding and becoming hemispherical, margin 

 usually entire, 2-3 cm. across, fleshy and rather brittle ; disc 

 clear sulphur-colour ; externally white, downy, due to the 

 presence of thin-walled, hyaline, somewhat pointed, sparsely 

 septate hairs, 40-60 X 5-6 /x, base of ascophore usually more 

 or less furnished with anastomosing ridges, or with irregular 

 depressions ; stem 2-3 cm. long, 4-6 mm. thick where it
