26 ■ ERYTHEA. 



Perithecia thickly scattered, covered by the epidermis, 

 which is raised into pustules and ruptured, but the perithecia 

 are for the most part not erumpent. Sporules oblong-ellip- 

 tical or cylindrical, obtuse, brown, mostly a little curved, 

 15-22x6-10//, scarcely constricted at the septa. 



Differs from Camarosporium celtidis, E. & E., in the 

 absence of any longitudinal septa, and from Hendersonia 

 fusarioides, Sacc, in its shorter, broader sporules. 



Hendersonia Fraxiui. On dead limbs of Fi^axinus viri- 

 dis, March 6, 1895 (No. 1676). 



Perithecia erumpent from the bleached fibers of the inner 

 bark, from which the epidermis has fallen, about ^ mm. 

 diam., subhemispherical becoming more or less flattened. 

 Sporules oblong-elliptical, 3- (exceptionally 4-) septate, not 

 constricted ; hyaline and continuous at first, finally brown, 

 11-13x5-6/1. 



H. Pyri, Fckl, has basidia much longer than the sporules, 

 but in the Kansas specimens no basidia were observed. 



Pestalozzia Kansensis. On old dead leaves of Quercus 

 macrocarpa^ Jan., 1894 (No. 1357). 



Acervuli hypophyllous. Conidia oblong-fusoid, 4-septate, 

 the terminal cells hyaliue and conical, the three inner cells 

 pale brown (not yellow brown), entire length 16-18/1, colored 

 part ll-13x5-5|//, terminal bristle oblique, 15-20/t long, ped- 

 icels about 15/< long. 



Comes near Pestalozzia Saccardoi, Speg., which differs in 

 having the inner cells nearly opaque. P. pallida, E. & E., 

 has the conidia rather smaller and nearly hyaline. 



Pestalozzia (Enotherae. On dead stems of CEnothera 

 biennis, March 7, 1895 (No. 1682). 



Acervuli gregarious, erumpent-superficial, orbicular or 

 subelliptical, |-| mm. diam. Conidia obclavate-obloug, 

 3-septate, not constricted, subinequilateral or slightly curved, 

 10-12x3-4/f, rounded at the base, acute at the apex ; terminal 

 cell mostly hyaline, surrounded by a short, hyaline, mostly
