HIGHER FUNGI OF THE HAWAIIAN ISLANDS 1 



EDWARD ANGUS BURT 



Mycologist and Librarian to the Missouri Botanical Garden, Professor 



of Botany in the Henry Shaw School of Botany of 



Washington University 



The fungi enumerated in the present list consist of the Basidio- 

 mycetes collected by Professor F. L. Stevens in the Hawaiian 

 Islands during the summer of 1921, and of the fungi in the 

 Bernice Pauahi Bishop Museum Herbarium which were brought 

 to the United States for study in connection with the Stevens 

 collections. Most of the specimens from the Museum were 

 collected by Professor C. N. Forbes. 



The 150 numbers which comprise this lot of specimens belong 

 to 61 species; more than three-fifths of the specimens and nearly 

 half of the species are Polypores ; 1 1 per cent, or the 7 species, 

 Lepiota xylophila, Crepidotus rhizomorphus , Fomes hawaiensis, 

 Fomes fasciculatus , Poria fasciculata, Corticium granulare, and 

 Epithele hydnoides, are regarded as indigenous. Lepiota xylo- 

 phila Pk. and Fomes hawaiensis Forbes were described several 

 years ago; the other 5 species named above are now described 

 as new. Of the species fully determined, which occur in other 

 countries besides the Hawaiian Islands, about 43 per cent are 

 of cosmopolitan distribution, 13 per cent are confined to tropical 

 regions of both America and Asia and East Indies, 243^ per cent 

 occur in the Philippines and East Indies but not in America so 

 far as known at present, and about 6 per cent of the species are 

 regarded as indigenous members of the fungal flora of the north 

 temperate region of North America. Hence the purely North 

 American component in the higher fungal flora of the Hawaiian 

 Islands is hardly a fourth as great as that of Asiatic, East Indian, 

 and Philippine sources, so far as the present small number of 

 species show. 



In accordance with the instructions received, a portion of each 

 specimen, if sufficiently ample, has been retained in the Missouri 

 Botanical Garden Herbarium and the remainder returned to
