Graff: Fungi and Lichens from Guam

list of fungi collected by these two botanists. The next collec- 

 tion of Guam plants was made by Adelbert de Chamisso de Bon- 

 court, botanist of the Romanzoff Expedition, which visited the 

 place in November, 1817. His collection, though containing 

 numerous flowering plants and ferns, contained no fungi from 

 these islands. It seems strange that while the Philippines, 

 Hawaii, Chili, Brazil, and a number of other places are repre- 

 sented by specimens in his fungous collection, Guam should have 

 been slighted in this respect. It may have been that the stay of 

 the Expedition here was very short or material of this class of 

 plants may have been neglected while here. 



The first expedition on which any specimens of fungi were 

 gathered and preserved was that under the command of Louis 

 Freycinet, which visited Guam in March, 181 9, a little more than 

 a year after Chamisso. The expedition had been joined by 

 Charles Gaudichaud-Beaupre as physician and botanist and it 

 was through his efforts that an extensive botanical collection was 

 made. Several months were spent in the exploration of Guam 

 and the neighboring islands of Rota and Tinian. The expedi- 

 tion made what was probably the largest single collection to date 

 in the botanical exploration of Guam. Unfortunately, however, 

 on the return voyage their vessel, the " Uranie " foundered while 

 in the Falkland Islands. The hold in which the herbarium was 

 stored became flooded and more than half the botanical collec- 

 tions were destroyed. 



Among the remaining material there are sixty-seven species 

 designated as fungous specimens, of which twenty-five are cred- 

 ited to the Marianne Islands and the larger portion of the re- 

 mainder to the following localities : Rio de Janeiro, Isle of France, 

 Rawak, and the Hawaiian Islands. The number classed as lichens 

 is slightly larger, being ninety-seven in all, of which eighteen are 

 from the Marianne Islands. The arrangement, classification, and 

 description of new species in both the fungi and lichens was pub- 

 lished by Persoon between 1826 and 1830 and a goodly percentage 

 were described by him as new. Of this material all but thirteen 

 are recognizable and will be found distributed in proper order in 

 the list to follow. The uncertain species include the following 

 and have been omitted : Lycogala marianna, Sphaeria laguncula,
