Fuirena umbellata. SEDGE. 
Family Cy peraceae. 
A sedge, growing in damp places, belonging to the tribe Scirpeae, with dark-brown, 
dense clusters of sessile spikelets and leafy triangular stems, which are glabrous 
except at the tomentose inflorescence. Plant perennial; rootstock hard, stoloniferous 
or shortly creeping with filiform root fibers; stolons hardening into rhizomes, clothed 
with ovate-lanceolate striate scales; stem 30 to 120 em. tall, stout or slender, ribbed; 
leaves variable, 15 to 30 em. long, up to 14 mm, broad, linear-lanceolate, obtusely 
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 mim. 
long, membranous, broadly obovoid, retuse or 2-lobed, glabrous or puberulous and 
ciliate, keel stout, of 3 veins meeting in a stout scabrid cusp half as long as the 
glume; scales obovate-quadrate, upper margin thickened, cuspidate; stamens 38, 
anthers rather stout, apiculate; nut 1.5 to 2mm. long, stipitate, trapezoidal, trigonous, 
long-beaked, the angles acute, obscurely 3-ribbed dorsally, smooth, pale; style as 
long as the nut.

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.) Sehrot, belonging 
to the Auriculariaceae; Fomes secabrosus (Pers.) Fr., Polyporus kamphoeveneri br. 
(P. mariannus Pers.), Polystictus sanguineus (L.) Mey., P. wanthopus Pr. (2. saceatus 
Pers. ), belonging to the Poly poraceae; and Schizophyllim alnewn (L.) Sechrot., 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.
