PSEUDO -SCLEROTIA OE LENTINUS SIMILIS, &C. 17 
binds together earth in a large compact mass. This is vouched 
for in recent times by Eichelbaum, but detailed accounts of 
the structure of any such mass connected with a Lentinus 
have not, so far as I am aware, been published. 
Lentinus similis and Lentinus infundibuliformis provide a 
third type in which the skeleton of the pseudo-sclerotium 
consists of the wood of the host plant. 
Whether these three types are definitely associated with 
different species of Lentinus, or whether they are merely 
stages which may be assumed by the sclerotium of any one 
species, must remain an open question on the available 
evidence.
