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.
