and a pileus I mm. in diameter, while in older plants the stem was 

 often 2 cm. long and the pileus as large as 4 mm. in diameter, 

 the convolutions being more marked in old than in young plants. 

 To me it would seem doubtful if these two species can be sepa- 

 rated on these characters. A single specimen of Mitrula musi- 

 cola was found in the Garden collection. 



Mitrula irregularis (Peck) Durand, Ann. Myc. 6: 398. 1908 

 Several specimens of this species were collected at Tolland, 

 where the plants occur on bare ground or among moss in conifer- 

 ous woods. The species has formerly been reported from On- 

 tario and New Brunswick south to the District of Columbia.

This species was found to be very common on damp soil, both 

 at Tolland and in Geneva Creek Canyon. The plants are bright- 

 red and the spores smooth, with one large oil-drop often sur- 

 rounded by numerous smaller ones.

Pcziza modesta Karst. Myc. Fenn. 1 : 64. 1871. 

 Crouania asperella Rehm, Hedwigia 24 : 226. 1885. 



This species was collected in Pennsylvania in 1881 and distrib- 

 uted by Mr. Ellis in North American Fungi 841 under the name 

 of Peziza modesta Karst., which species is undoubtedly a synonym 

 of the above. The species has also been collected and reported 

 by the writer from Iowa. Several collections of this species
