LIFE HISTORY OF HYPOCREA ALUTACEA.* 
GEORGE F. ATKINSON. 
(WITH PLATES XIV-XVI) 
Hy pocrea alutacea (Pers.) Tul. is an interesting plant, not only 
“mM account of its history, but because of its peculiar form and color 
“tharacters, taken in connection with its structure. In shape it 1s 
like a club or spatula, one to three inches high, resembling in form 
other members of the old genus Sphaeria now placed in the genera 
“Xylaria and Cordyceps. It differs from the Xylarias in not being 
black, as well as in differences of texture and structure. It resembles 
more nearly a simple Clavaria, in which genus it was first placed as 
Clevaria simplex Schmiedel.2_ It resembles also a Cordyceps, in 
Which genus it has also been placed, and it is even said to grow 
‘Sometimes on insects. Some forms are also strikingly like species 
of Spathularia among the Discomycetes. To the collector, therefore, 
when he first finds it, it calls forth 
of its simple 
aR ic on the surface of the larger fungi, resembling in this respect 
of the species of Hypomyces.
