Mexico. 

 Our knowledge of the fungi of Mexico is very limited. Sev- 

 eral papers appeared early bearing on the fungi of this region 

 obtained from various collectors. More recently collections have 

 been made by T. S. Brandegee, and E. W. Hoi way; the latter has 

 made several trips seeking especially Uredinales. As in all the 

 countries of Spanish settlement, the work of collecting and describ- 

 ing the lower plants of Mexico will devolve on the Anglo Amer- 

 icans, and long before the mycological flora of the United States is 

 thoroly known, that of the tropical regions to the southward 

 will be collected by American botanists and the progress in our 

 knowledge of all North America will become more and more uni- 

 form. We can refer to the following papers bearing on the my- 

 cological flora of Mexico: 



Berkeley. On some new Fungi from Mexico. Jour. Linn. Soc. 

 9 : 423-425. PL 12. 1867. 



Describes six species. 



Ellis & Everhart. New West American Fungi. Erythea, 5 : 

 5-7. 1897. 



Descriptions of eight species, six from lower California. 



Fries. Novae symbolae mycologicae in peregrinis terris a bot- 

 anici Danicis collectae. Nova Acta Sci. Upsal. i : 17-136. 1851, 



Novarum symbolarum mycologicarum mantissa. No\a 



Acta Sci. Upsal. i : 225-231. 1851. 



Includes a number of species from Mexico. 



Holway. Mexican Fungi. Bot. Gaz. 24: 23-38. 1897. 

 Forty-seven new species mostly Uredinales. 



Central America. 

 Most of our knowledge of the fungi of Central America has 

 been derived from the explorations of a single expedition fitted 

 out from the Iowa State University ; the results have not all been 

 published but the following have appeared ; duplicates of a con- 

 siderable part of this collection are in the Ellis herbarium : 



Ellis & Everhart. New Species of tropical Fungi. Bull. Lab. 

 Nat. Hist. State Univ. Iowa, 4 : 67-72. 1896. 



Descriptions of eleven Nicaraguan and two Mexican species. 



Macbride. Nicaraguan ^lyxomycetes. Bull. Lab. Nat. Hist. 

 State Univ. Iowa, 3 : 377-383. PL 10. 1893.
