Peziza 227 



Quite common on burned places and rather attractive because 

 of its violet color, although not very conspicuous. 



10. Peziza griseorosea Ger. Bull. Torrey Club 6: 31. 1875. 

 Apothecia shallow cup-shaped, externally whitish-pruinose, 



sessile, the flesh rather thin, the color grayish-ochraceous ; 

 reaching a diameter of 2-4 cm.; hymenium concave, pale- 

 rosaceous to subochraceous; asci cylindric or subcylindric; spores 

 1-seriate, ellipsoid, becoming sculptured, 7-10 X 15-18 /x, hyaline 

 or slightly yellowish; spore-sculptured taking the form of minute 

 warts; paraphyses slightly enlarged at their apices. 



On the ground. 



Type locality: Poughkeepsie, New York. 



Distribution: New York and Connecticut to Wisconsin and 

 Virginia. 



Illustration: Cooke, Mycographia pi. 65, f. 240. 



An authentic specimen of this species from the herbarium 

 of Gerard is deposited in our collection at The New York Botan- 

 ical Garden. A number of specimens from various localities 

 have been referred to this species but always with more or less 

 doubt, since it is difficult to determine the exact color from 

 the dried specimens and the species was originally distinguished 

 chiefly on that character. When possible, color records should 

 be preserved in such cases as this in connection with field records.
