Abnormal Collybia radicata. — When collecting Mush¬ 
rooms near Sandusky, Ohio, the past season, some specimens of 
Collybia radicata were found in peculiar habitat, but they had 
adjusted themselves advantageously to the situation. They were 
growing on a rotten log, only the upper side of which had com¬ 
pletely rotted away. The specimens were unable to send their 
‘Toot” into the rotten wood, and in one case no such prolonged 
stipe was developed. In the other specimen the root-like por¬ 
tion, peculiar to this species, took a horizontal direction, applying 
itself closely to the moist surface of the decaying log. Sketches 
of these two abnormal forms are shown in Figs, io and n, Plate 
73. On the same plate is shown a specimen from a distant lo¬ 
cality in which the cap is tipped up on one side by the abnormal 
lateral growth of the apical portion of the stipe; see Fig. 12.
