spore like those of L. tuberculata but much smaller, about twenty 
to twenty-five around the circumference of the spore, hyaline; 
paraphyses enlarged above and filled with orange granules. 
On soil among moss near Yonkers, New York. 
This species has been frequently collected and much attention 
has been given to a study of the spore characters. As might at 
first be thought, the small wart-like markings have never been 
found to intergrade with those of L. tuberculata in which they are 
twice as large.
