Fungi. 



Very little is known of the Fungi of Guam. Among the few species collected liy 

 Gaudichaud on the island are Auricularia auricula-judae (L. ) Schrot, lielonging 

 to the Auriculariaceae; Fomes scabrosus (Pers.) Fr., Polyporus kamphoeueneri Fr. 

 (P. mariannus Pers.), Polysliclus sanguineus (L.) Mey., P. xanthoi>us Fr. (P. snrculns 

 Pers.), belonging to the Polyporaceae; Sind Schizophylbim alneuin (L.) Schrot., belong- 

 ing to the .\garicaceae. From the results of observations on other islands it is certain 

 that a collector of Fungi would have a fine field in the Marianne Islands. Fungi 

 abound everywhere, on the ground, on decaying wood, on tree trunks, on the leaves 

 of water plants, grasses, and forest trees, and upon rotting fruit. Some of them 

 are like great solid masses of gingerbread, others are as delicate as coral, and others 

 appear as microscopic rusts, molds, or mildew. One of the most common is 

 brightly luminous in the dark.
