had been removed several other smaller ones grew from the 

 same place. The tree was finally so weakened at this point 

 that it was blown over during a storm. AVhen fresh the 

 pileus is somewhat watery but firm, whitish, and smooth 

 or nearly so. The context or flesh is white, soft and punky, 

 and has a sweetish odor when dry. The tubes are 0.3 to 

 1 cm. long, the mouths small and white. 



Polyporus induratus Lloyd (Fig. 6) — Three specimens 

 of this plant have been collected from a box elder stump 

 near the University campus in Urbana. Since it was new 

 to me I sent a specimen to Mr, C. G. Lloyd of Cincinnati. 

 It proved to be new to him also and he named it as above 

 and reported it with a brief description in his Letter No. 

 68, page 11, note 743. It is a large plant, extremely tough 

 and spongy when fresh, and becoming hard and punky 

 when dry. The whole plant is light colored when fresh but 

 turns black where bruised or wounded and darkens in dry- 

 ing. The tubes are very minute and only 3 to 5 mm. long. 



Polyporus dryadens (Pers. ) Fr. (Fig. 7) — This plant is 

 considered rare and is usually reported as growing on liv- 

 ing oak trees. The specimen shown in the photograph 

 was found on an old oak stump north of Urbana. I am 

 indebted to Dr. L. O. Overholts for its identification. When 

 fresh the pileus is spongy and somewhat watery, grayish 

 brown in color and glabrous. The context is also brown 

 and becomes somewhat brittle when dry. The tubes are 

 small but sometimes as much as 2 cm. long, 



Entoloma grayanum Pk. (Fig. 8) — Entoloma is a dan- 

 gerous genus and this species like its near relatives is 

 probably somewhat poisonous. It is a very ordinary look- 

 ing mushroom growing 6 to 8 cm. tall with its gray or drab 

 colored cap 3 to 6 cm. broad. The gills are attached and 

 there is no ring on the stem. The spore when caught on 

 paper are light salmon color. The specimens photographed 

 were collected in the University woods near Urbana. 



Sfropharia caesifolia Pk, (Fig. 9) — One morning while 

 collecting Agaricus campestris in a cemetery north of 

 Urbana I chanced to pick up a specimen which looked the 

 same as the others but which on turning it over I found to 

 have beautiful light blue gills instead of the familiar pink. 

 Closer examination showed that the gills were attached 

 and indicated that it was a Stropharia instead of an
