NEW KANSAS FUNGI. 27 



oblique bristle, 5-7// long and generally arising from a point 

 a little to one side of the apex. 



This is closely allied to P. Bfochceta, Desm., but the acer- 

 vuli are larger and the mature conidia have only the terminal 

 cell hyaline and sometimes all the cells are pale brown ; the 

 conidia are also different in shape. 



Pestalozzia flbriseda. On weather-beaten wood of Rhus 

 glabra (No. 1931). 



Acervuli gregarious, subhysteriform, ^1 mm. long. 

 Conidia oblong-elliptical, 3-septate (5-septate including th^ 

 two septa that cut off the small, terminal, hyaline cells), 

 brown, 15-20x8//, with slender pedicels about 25// long and a 

 short (10-12//), oblique terminal bristle. 



Lal)rella infuscans. On weather-beaten pine boards, 

 March, 1891 (No. 1425). 



Perithecia subelliptical, minute, flattened, and verj^ thin 

 above with an elongated opening as in Hystermm, minute {\ 

 mm. long), black, not polished, when dry more or less 

 collapsing and the opposite sides rolling together, as in 

 Hysterium, with the sides loosely close. Texture of the 

 perithecia ratlier coarsely cellular with a tinge of green 

 (under the microscope). Sporules short-elliptical or sub- 

 globose, hyaline, without nuclei. The perithecia are gre- 

 garious, on elliptical spots slightly darker than the surrounding 

 wood, by which it is easily recognized. 



Cladosporium brevipes. On living leaves of Popiilns 

 monilifera, Sept. 18, 1894 (No. 1576). 



Spots orbicular, grayish brown with a darker border, 3-6 

 mm. diam., caused by the puncture of an insect. Hyphge 

 amphigenous, short (12-15//), forming black tufts thickly 

 scattered over the central parts of the spots. Conidia, oblong- 

 fusoid, yellowish, continuous or uniseptate (exceptionally 

 2 to 3-septate), 12-15x3//. The hyphse are about the same size, 

 color and shape as the conidia. 



This species is quite common on seedling trees 1-4 feet 

 high on sand bars along streams.
