 Peziza crouani Cooke, Mycogr. 13. 



Plants small, 2 to 5 mm. in diameter, at first concave, becom- 

 ing nearly plane, orange ; asci very long, cylindrical to clavate, 

 150 by 16 to 18/1,; 8-spored; spores globose with large central 

 oil-drop, externally delicately reticulated, 15/i, in diameter; re- 

 ticulations regular with the meshes rather small ; paraphyses 

 slender, enlarged upwards, filled with orange granules. 



On rather sandy soil among moss, Iowa City. 



One collection of this species was made in Iowa and the plants 

 are characteristic in everj' way. The individuals are larger 

 than the other species of the genus here described and the spore- 

 markings are distinct from an}- of the other forms studied.
