A MONOGRAPH OF THE GENUS PODAXIS DESV. (= PODAXON FR.). 77 



all swollen at the base ; mass of spores blackish brown ; capillitium- 

 threads very rare, with indistinct spiral markings ; spores irregu- 

 larly globose or broadly elliptical, smooth, clear dark brown, 

 10-12 or 10 x 12 (i. 



The present species is characterised by the peridium being very 

 obtuse and broadest at the apex, the stuffed, subequal stem, and 

 subglobose, brown spores. Peridium 6-8 x 3-4 cm., stem 11-18 

 cm. long. 



"Arizona, Dr. Palmer, Herb. W. G. Farlow" specimen sent to 

 Berkeley, now at Kew, and accepted as type of the present 

 species. New Mexico (Gerard, No. 287) ; Rio Grande, N. Mexico 

 (Wi-ight). 



7. Podaxis Emerici (Berk.). — Peridium elliptic-oblong, covered 

 with dark-coloured, squarrose, fibrillose scales ; stem elongated, 

 attenuated upwards, hollow ; mass of spores olive-brown ; spores 

 broadly elliptical, smootb, with a distinct apiculate hilum, olive 

 with a tinge of brown, 20-22 x 12-14 /x ; capillitium obsolete. 



Podaxon Emerici Berk, in herb. — Peridium 6-8 x 4 cm., stem 

 14-16 cm. long. Characterized by the scaly peridium and the 

 large olive spores.

Description of the Figures on Plates 294 and 295. 



Plate 294. — Fig. 1, Podaxis indica, vertical median section of a young spe- 

 cimen before differentiation of the gleba ; nat. size. 2, P. indica, vertical 

 median section of young specimen after differentiation of the gleba, a ; central 

 axis, b ; peridium, c ; basal portion that eventually elongates and forms the 

 stem, d; nat. size. 3, P. indica, portion of an ascogenous branch; x 1200. 

 4, P. indica, portion of an ascogenous branch with empty, shrivelled asci ; 

 X 1200. 5, P. indica, an ascus containing two immature spores; x 1200. 

 6, P. indica, portion of a capillitium-thread showing the spiral marking, and at 

 one end broken up into a flat, spirally-coiled ribbon ; x 1200. 7, P. indica, 

 diagrammatic section of a capillitium-thread showing the ridges on the inner 

 surface of the wall arranged spirally. 8, P. indica, hyphte from young speci- 

 men ; x 1200. 9, P. indica, spore in optical section, showing the germ-pore ; 

 X 1200. 10, Podaxis carcinomalis, a small ascogenous tuft ; x 1200. 11, Dia- 

 grammatic median vertical section of an ascogenous branch of Podaxis Emerici, 

 showing the incrassated branch with but few septa ; if this is compared with 

 the basidia of Tulostoma, fig. 12, it will be seen that the only morphological 

 distinction between the two consists in the absence of septa in the latter. 

 12, Tuhstoma xnisillum, basidia with spores; x 400. 13 & 14, spores of above 

 in different stages of development ; x 1200. 15, Elaphomyces variegatus, 

 portion of an ascogenous hypha with asci in various stages of development ; 



x 400. 16, 17, 18, asci of same containing one, two, and four spores 

 respectively ; x 400. 



Plate 295. — Fig. 19, Podaxis Farlowii, entire fungus ; nat. size. 20, spores 

 of same; x 350. 21, spore of same; x 1200. 22, Podaxis Emerici, entire 

 fungus ; nat. size. 23, vertical median section of same ; nat. size. 24, spores 

 of same ; X 350. 25, spore of same, showing hilum, a ; and germ-pore, b ; 



x 1200. 26, spore of same, showing outer membrane of spore split and partly 

 removed; x 1200.
