 It will be noted that a considerable number of species given by 

 Persoon in his fungous list are now known to be lichens and will 

 be found under lichen genera in the portion of this paper fol- 

 lowing. 



Montagne, in 1843 and 1856, published among notes on other 

 fungi a few scattered ones on some species collected by Gaudi- 

 chaud, all of which are in the herbarium of the Paris Museum. 

 A few lichens also received attention but among the several spe- 

 cies mentioned nothing was reported new to the islands. 



No further reference to Guam fungi can be found till 1901, 

 when Schumann and Lauterbach published their "Flora der 

 Deutschen Schutzgebiet in der Sudsee." They include an enum- 

 eration of six fungi and three lichens. This enumeration does 

 not seem to designate plants collected during this voyage but 

 rather to have been taken, for the most part, from Gaudichaud's 

 publication. The Marianne Islands are not mentioned in their 

 itinerary and were probably not visited. The fungi listed by 

 them include Auricularia auricula- judae (L.) Schrot., for which 

 they consider Persoon's Guam type A. ampla a synonym and sug- 

 gest that probably his A. ornata should receive a similar classi- 

 fication. Under Fomes scabrosus (Pers.) Fr., they include Per- 

 soon's two Guam species, Polyporus scabrosus and P. fusco- 

 badius. Polyporus mariannus Pers. is considered by them as 

 P. kamphoveneri Fr., and is so listed. Polyporus sanguineus L., 

 P. saccatus Pers., and Agaricus alneus L., as reported by Per- 

 soon, are given under the names Polystictus sanguineus (L.) 

 Mey., P. xanthopus Fr., and Schizophyllum alneum (L.) Schroet, 

 respectively. Among the lichens Dictyonema membranaceum 

 /Vgardh., Coenogonium linkii Ehrenb., and Ramalina subfraxinea 

 Nyl., are enumerated from this locality. 



In 1905 SafTord published in his "Useful Plants of Guam" a 

 short list of six species of fungi which is identical with that of 

 Schumann and Lauterbach, exclusive of their lichens, and is very 

 evidently based on their list rather than any collection of his own 

 or even on Gaudichaud's record. This is the last published list
