The fungus is said to be fairly plentiful in the locality where: 
found. Sessile, somewhat ungulate forms are found attached 
to stumps, while the stipitate forms grow up from buried roots, 
as in the case of G. lucidum. 
The name simulans has been given to the species on account 
of its remarkable resemblance to Fomes subresinosus, Murr. So 
striking is this that the suspicion remains that they must be 
connected. Yet careful search has failed to disclose any trace 
of Ganoderma spores in the specimens of F. subresinosus examined, 
while in this plant they are very abundant. On the other hand 
it is to be noted that the spores of F. subresinosus are not hyaline 
and globose as described, but large (17-20 x 10-12-5y), ovoid, 
and slightly tinged with brown. They are however perfectly 
smooth, and have no indication of the outer hyaline wall 
characteristic of Ganoderma. The spores of F. subresinosus 
are in fact like those of the genus Amauroderma.
