286 FUNGI. 
recorded from Senegal, from Egypt, or from other parts of 
Africa, so that, with the above exceptions, the continent may 
be regarded as unknown. 
From this imperfect summary it will be seen that no general 
scheme of geographical distribution of fungi can as yet be 
attempted, and the most we can hope to do is to compare 
collection with collection, and what we know of one country 
with what we know of another, and note differences and agree- 
ments, so as to estimate the probable character of the fungi of 
other countries of which we are still in ignorance. It is well 
sometimes that we should attempt a task like the present, since 
we then learn how much there is to be known, and how much 
good work lies waiting to be done by the capable and willing 
hands that may hereafter undertake it.
