244 FLORA OF TASMANIA. [ Fungi, by M. J. Berkeley. 
Has. On dead wood, Archer. 
Whole plant of a pale red-brown. Pileus 4 inch across, plane, subcarnose, striate. Stem 1 inch high, scarce a 
line thick, downy at the base, fibrillose. Gills arched, moderately broad and distant, but more numerous than in 
A. umbelliferus, decurreut, pale reddish-brown.—PrATE CLXXXI. Fig. 3; a, plant, nat. size; b, vertical section, 
magnified. 
18. Agaricus (Omphalia) umbelliferus (Linn.; Fr. Ep. p. 124). 
Haz. On the ground, Gunn, Archer. 
Mr. Archer's is a pallid form, with very decurrent gills. Gunn collected abundant specimens of a variety vary- 
ing from primrose to orange, according to age. Other forms also seem to be abundant. 
19. Agaricus (Omphalia) flavo-croceus (Berk.); pileo convexo umbilicato glabro stipiteque 
elongato ineguali solido flavis, lamellis latis postice decurrentibus croceis. 
Has. Under logs, Archer. | 
Pileus $ inch across, convex, umbilicate, pale-yellow, glabrous; margin jagged. Stem 9 inches high, 1 line 
or more thick, unequal, stringy, dull saffron-yell w, downy at the base. Gills rather numerous, broad, abruptly de- 
current, saffron-yellow ; margin entire; interstices even.— The numerous gills separate this from the yellow variety 
of A. umbelliferus, while it has the colours but not the narrow gills of A. chrysophyllus. 
20. Agaricus (Omphalia) integrellus (Pers. Ic. et Desc. t. 13. f. 1). 
Has. On dead wood, Archer. 
21. Agaricus (Pleurotus) tephrophanus (Berk.); pileo excentrico infundibuliformi brunneo 
rivuloso pulverulento, stipite hirto e basi strigosa oriundo, lamellis latis postice emarginatis. 
Has. On charred wood, Archer. 
Pileus 1 inch across, brown, minutely wrinkled and pulverulent, infundibuliform, thin. Stem brown, hispid, 
# inch high, 1 line thick, springing from a strigose base. Gills few, broad, emarginate behind, transversely striate, 
pale.—This curious species approaches in many respects to Paxillus atrotomentosus, but the gills are of a different 
character. 
22. Agaricus (Pleurotus) phosphorus (Berk. in Hook. Lond. Journ. Bot. vii. p. 572). 
Haz. On roots of trees, Oct.—Feb., Gunn. 
Bo phosphorescent that Mr. Gunn was able to read by its light, and it remained luminous six days or more.— 
A specimen, supposed to belong to this species, but possibly 4. salignus, was found growing on Acacia dealbata, 
from ue cavity in which the caterpillar of a Cossus had been nursed, and entirely filling up the shell of the pupa 
with its mycelium, so as at first sight to appear parasitic upon the insect. 
23. Agaricus (Pleurotus) palmatus (Bull. t. 216). 
Var. sessilis. 
Has. On dead wood, Archer. ` 
This appears to be a sessile form of the plant of Bulliard. There is but a single specimen. 
24. Agaricus (Pleurotus) diversipes (Berk.); pileo umbilicato 1. laterali pelliculo gelatinoso ves- 
tito, stipite subcartilagineo compresso cavo elongato brevi L obsoleto, lamellis distantibus decurrentibus, 
interstitiis levibus. (Tas. CLXXXI, Fig. 4.) 
Has. On dead wood, Archer. 
Pileus 1-2 inches across, central or lateral, umbilicate or depressed behind, covered with a gelatinous pellicle. 
= very variable, elongated and slender, short or obsolete, subcartilaginous, downy at the base, flat, hollow. Gills 
stant, — — interstices even.—Allied to 4. Tasmanicus, but distinguished by various characters.—
