 acuminate, 3 to 5-veined, glabrous or ciliate toward the base, margins smooth or 

 nearly so, sheaths long, closed, mouth with a ciliolate brown ligule; spikelets 5 to 8 

 mm. long, ovoid or oblong, sessile, crowded in simple or compound, axillary, 

 peduncled and terminal, sometimes subpanicled clusters 12 to 25 mm. in diameter, 

 dark brown, the peduncle tomentose or villous, rachilla slender; bracts under the 

 clusters short, cuspidate; glumes closely imbricated, at length deciduous, 3 mm. 

 long, membranous, broadly obovoid, retuse or 2-lobed, glabrous or puberulous and

Fungi. 



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

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

 to the Auriculariaceae; Fomes scabrosus (Pers. ) Fr., Poll/poms kamphoeveneri Fr. 

 (P. mariannus Pers.), Polystictus sanguineus (L.) Mey., P. xanthopus Fr. (P. saccatus 

 Pers. ), belonging to the Polyporaceae; and Schizophyllum alneum (L. ) Schrot., belong- 

 ing to the Agaricaceae. 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.
