In the following descriptions the term receptacle has been used to 

 designate the main body of the fungus ; the side from which the peri- 

 thecium springs being spoken of as the inner, while that bearing the 

 pseudoparaphyses is spoken of as the outer, where this distinction is 

 possible. The first two superposed " stem cells " of the receptacle are 

 spoken of as the basal and supra-basal cells. 



STIGMATOMYCES Karsten (1871). 



Stigmatomtces entomophila (Peck). 



Appendicularia entomophila Peck, 1. c. 



Appendiculina entomophila Berlese, Malpighia, Vol. III. p. 59. 



Through the kindness of its discoverer, the Rev. J. L. Zabriskie, the 

 writer has been enabled to examine authentic specimens of this inter- 

 esting and distinct species, which proves to belong without question to 

 the present genus. The antheridial appendage is proportionately some- 

 what smaller than in its near ally {S. Baeri (Knoch) Karst.), but has 

 the same peculiar structure and bears the same relation to the peri- 

 thecium ; and structural differences which could separate it generically 

 are wholly wanting. Berlese in the paper referred to calls attention 

 to the fact that Appendicularia has been preoccupied among the Mp- 

 lastomaceae, and proposes the substitution of Appendiculina, which, 

 however, proves to be needless. 



PEYRITSCHIELLA nov. gen. 



Receptacle composed of two superposed basal cells, above which 

 it is multicellular, one cell on the inner side forming a short, sharp 

 projection. Perithecium one, sometimes two; when single, terminal, 

 nearly median, subconical, the spreading apex symmetrically four- 

 lobed. Pseudoparaphyses arising from several different points on 

 either side of the receptacle. 



Petritschiella curvata nov. sp. 



Characters of the genus. Usually strongly curved, colorless except 

 the large, jet-black piece of attachment, and the bases of the pseudo- 

 paraphyses which are also black and strongly constricted in the 

 middle. Paraphyses colorless, cylindrical or subclavate, septate or 

 obscurely septate ; arising in three to five groups, each made up of 

 from one to three pseudoparaphyses, and placed alternately at different
