peculiar purplish tint. In a short time the white flocculent threads 

 of the fungus appear on the cut surface, soon to be followed by the 

 more wax}' and colored patches ot spores, thus showing that the 

 mycelium has permeated the diseased flesh of the tomato. The 

 affected tomatoes become very watery and any surface on which 

 a diseased tomato lies, soon becomes wet from the exuding juices. 

 From the constancy with which this fungus appears in connection 

 with the disease, it would appear that it might be regarded as the 

 cause of the decay, but there are circumstances that point to some 

 more subtle agent of the mischief. Further investigation is neces- 

 sary to determine satisfactorily the source of the disease. 



PEZIZA TRUNCICOMES, Ger. 

 Decaying prostrate trunks of deciduous trees. Knowersville, 

 Albany county. May. 



PEZIZA ALBOVIOLASCENS, A. & S. 



Old chestnut rails. Conklingville. September. 



HELOTIUM EPISPH-ffiRICUM, N. sp. 



Receptacle minute, .012 to .02 inch broad, gregarious, subsessile, 

 at first subhyaline, then reddish-yellow, the disk nearly plane, asci 

 subcylindrical ; spores oblong or lanceolate, .0002 to .00025 inch 

 long, .0001 to .00012 broad. 



On old Hypoxylon Morsel. Elizabethtown. September. 



It resembles H. citrinum in habit, but is very much smaller. 



• ASCOMYCES LETIFER, N. sp. 



Indefinite, hypophyllous, often occupying the whole lower sur-* 

 face of the leaf and suffusing it with a glaucous bloom ; asci cylin- 

 drical, obtuse or subtruncate, .0016 to .002 inch long, .0006 to 

 .0008 broad ; spores minute, varying from narrowly elliptical to 

 subglobose, .00016 to .0002 inch long, .00008 to .00012 broad. 



Living leaves of mountain maple bush, Acer spicatum. Eliza- 

 bethtown. June. 



The species is very distinct from A. polysporus, which forms 

 definite spots. The attacked leaves soon turn black, wither and 

 die. Sometimes all the leaves on a branch are affected and the 

 fungus then causes a veritable blight.
