14. Pilobolus minutus Speg. Fung. Argent. 1, p. 176 (1880). 

 Sacc. Syll. vii. 186. 



Sporangiophores superficial, loosely gregarious, 2-5 mm. high, 

 at first fiUform-clavate, then ventricose and ellipsoid, above, always 

 hyaline, more or less elongated and filiform below. Sporangium 

 black, lenticular, 125-145 [x diam. ; spores spherical or eUipsoid, 

 granular, hyaline or faintly greenish-yellow, 7-8 [l diam.

 in the middle ; spores ellipsoid, 10-12 x 8-9 [j., with an orange 

 epispore. 



On cow dung. Tasmania (Rodway). Perhaps akin to a form of 

 P. Kleinii.

 Gard. Peradeniya, vol. vii, part 4, p. 297, says : " Scattered ; total
