Tulasne says that the septa are white and unchangeable ; 
Berkeley, that they become reddish when exposed to the air. 
Known at once (from M. variegatus , var. Broomeianus) by 
its much larger ovate spores, with a papilla at the apex, and 
its abominable smell, which resembles that of assafoetida. A 
single specimen in a room is so strong as to make it scarcely 
habitable. The walls of the cells when cut are whitish, but 
soon become red ; this is not, however, constantly the case.

This form, or more probably species, of which I have seen 
only an imperfect specimen, was found at Spye Park, in August, 
by Mr. Broome. It is as large as M. Broomeianus M 
variegatus , var. Broomeianus ), of which it has the bright rusty 
colour ; but the spores are much larger, equalling in size those 
of M. ambiguus , though of a very different form. There is
