Phoma Phytolacca, B. & G. 



Dead stems of poke weed, Phytolacca decandra. Albany. June. 



In our specimens the spores are a little longer than the dimensions 

 given in the description of the species and the perithecia are sometimes 

 slightly compressed or subhysteriiform. 



Phoma elevatum, n. sp. 



Perithecia numerous, small, rotund, oval or hysteriiform, sunk in the 

 matrix but occupying small elevations or ridges, black; spores ovate or 

 subelliptical, colorless, .0003 in. long, .00016 broad. 



Decorticated wood of deciduous trees. Adirondack mountains. June. 



The marked feature of the species and one suggestive of the name is 

 the position of the perithecia. Each one occupies a minute ridge or 

 pustular elevation of the wood. 



Phoma Pruni, n. sp. 



Perithecia small, slightly prominent, subconical, at first covered by the 

 epidermis, then erumpent, black; spores oblong-elliptical or subfusiform, 

 binucleate, hyaline, .00035 to .00045 U1 * l° n g> .00012 to .00016 broad, 

 supported on equally long or longer sporophores. 



Dead branches of choke cherry, Primus Virginiana, Karner. June. 



Phoma albifructum, n. sp. 



Perithecia numerous, large, .02 to .03 in. broad, conical or subhemis- 

 pherical, sometimes irregular and two or three confluent, erumpent, 

 black ; spores oblong-fusiform, acute at each end, two to four-nucleate, 

 colorless, .00065 to .00085 i n - l° n g> «ooo2 to .00025 broad, oozing out 

 and forming a white globule. 



Dead bark of maple, Acer rubrum. Karner. June. 



The perithecia and spores are unusually large for a Phoma and would 

 seem to justify Prof Saccardo's proposed genus Macrophoma. 



Sphaeropsis ribicola, G. & E. 

 Dead stems of Ribes flondum. Bethlehem, Albany county. May. 



Sphaeropsis alnicola, n. sp. 



Perithecia numerous, .0014 to .002 in. broad, prominent, hemispheri- 

 cal, erumpent, sometimes confluent, forming black patches t spores ob- 

 long, colored, .0006 to .00095 ^ n - l° n S> '°oo35 t0 .0004 broad. 



Dead branches of alder. West Albany. Apr. 



8. Aim C. & E. has smaller spores and inhabits living branches. 



Appendicularia, gen. nov. 



Plate 3, figs. 1-4. 



Perithecium thin, delicate, rostrate, supported on a filamentous pedicel 

 and accompanied by an appendage at its base. Entomophilous. 



This genus has been formed to receive the single species here de- 

 scribed. Its name is suggested by the appendicular organ at the, base of 

 the perithecium and supported with it by the common pedicel.
