elastic and internally gelatinous. Its edibility so far as I 

 know has not been tested but it does not look nor feel very 

 inviting and is probably to be classed as non-poisonous but 

 also non-edible. The specimens shown in the photograph 

 were collected in a woods near Urbana. 



Leotia hthrica Pers. (Fig. 2) — This plant like the pre- 

 ceding one is not at all rare and the only excuse for includ- 

 ing it here is to put it on record as occurring in Illinois. It 

 usually grows in clusters 5 to 8 cm. tall with the individ- 

 ual caps 1 to 3 cm. broad. The cap is irregularly hemi- 

 spherical and usually somewhat wrinkled. The whole 

 plant is of a peculiar yellowish green color. It is said to 

 l3e edible but not of good quality. It grows in the woods 

 often among mosses. The specimens photographed were 

 found in the Forestry of the University of Illinois. 



Basidiomycetes 



CratereUiis cornucopioides Fr. (Fig. 3) — The ''horn of 

 plenty", as this plant is called is easily overlooked because 

 of its blackish-brown color. It is trumpet-shaped, hollow 

 to the base, and sometimes as much as 10 cm. high though 

 more often not more than half that. It does not look veiy 

 palatable but is edible and is said to be very good. It also 

 drys well and so can be kept for future use. The speci- 

 mens photographed were collected in an open upland 

 woods in Vermilion County in September. 



Poli/porus giganteus iPers. ) Fr. (Fig. 4) — This plant 

 reminds one of the common P. frondosus but the branches 

 of the pileus are fewer in number, larger, and thicker. It 

 is characterized also by the fact that it turns black where 

 bruised and blackens also in drying. The plant is edible 

 but like all the edible species of this genus it is good only 

 when young and tender. The photograph shows a plant 

 collected within the Citv of Urbana. It was growins: on 

 the gi"ound near a buried stump. 



Pohjporus rohitiiophihis ( Murrill ) Lloyd (Fig. 5) — 

 Named robiniophilus because it was first found on locust 

 this plant has since been found as a wound parasite on 

 various deciduous trees but most frequently on locust, 

 hackberry and maple. The fine large specimen photo- 

 graphed grew on a hackberry in Urbana. It was produced 

 from a wound about 15 feet above the ground and after it
