Buff (hi.), the edge being pallid and sometimes in striking contrast. In the 
Sorghum Brown ami Army Brown specimens there is a line of Light Pinkisii 
Cinnamon (xxix.) inside the paler edge and in the Liver Brown plants a zone 
near Hazel (xiv. ). The edge is finely villose to nearly byssoid. The pores are 
very irregular, small, from about .2 to .S mm. in diameter, about M in 1 mm., 
meruloid and shallow or oblique or a little dee])er and Po)-in-liko with the 
dissepiments rounded and relatively thick and sometimes defective. Spores ? 
slightly curved, 5 x 1.8 /j.. Hyphae white, irregular, septate, to 5 /j. in diameter.

.S(i4. Poria subserpens Murr. (L., subserpens, somewhat creeping). — Descrip- 
tions, which differ somewhat, of two Australian collections are the following: — 
(1) Forming sharply determinate, irregular ])atches from 0.5 cm. up to 9x1! cm. 
in size, with somewliat raised edges and of a pallid dirty bufpy tint (near Pinkish 
Buff and Ochraceous Buff, xxix.), about 1 mm. thiqk with context very thin. 
Tlie pores are i-ather hexagonal, up to about 1 mm. wide with thin dissepiments. 
Hyphae white, d to d.7 y thick, varying a little in calibre and witli occasional 
nodular projections. (2) Forming shai'ply determinate neat-looking raised 
patches u)) to 15 x 2 cm., of a ]>ale buff' colour (a. little daiker than Pinkish Buff, 
XXIX.), ai)out 1 mm. thick, with very thin context and very narrow sterile edge 
of the same colour. Pores ratlier hexagonal, regular, about 0.5 mm. wide, about 
8 in 5 mm., the dissepiments thin and a little rounded. Hy])hae white, a little 
wavy and varicose, 2 to 3 y in diameter. New South Wales — Bullahdelah, 
Malanganee. August. (Figure 52. Left.) 
•‘!()5. Poria viiiaceo-rosea Rodw. et del. (L., vhuiccus, wine-coloured; roscus, 
ro.sy). — Forming thin encrusting patches up to 10 cm. or more, covering the 
lamellae of decaying Lenzites repanda Mont., and tending to fill up the spaces, 
a little greyer than Vinaceous Pink (xxviii.) becoming Terra-cotta (xxviii.) or 
darker. The gi'owing narrow sterile edge is filmy and subaraclinoid. Thickness 
up to 1 mm. Pores very minute, about 4 in 1 mm., orifices rounded, varying 
slightly in size, dissepiments obtuse, roumled. Ratlier friable. Hyphae with a 
faint tinge of yellow, 2.5 to 5.5 /j,. Spores not seen. Queensland — Bunya 
Mountains. October. 
3(5(). Poria Archeri Berk. (After William Archer, 1820-1874, F.L.S., a member 
of the first Legislature of Tasmania in 1851, later a Minister of the Crown 
and Secretary of the Royal Society of Tasmania, an assiduous botanical collector 
to whom with Gunn Hooker dedicated his “Flora of Tasmania”). — Widely 
effused, apricot-coloured (deeper than Capucine Buff, iii. ; more buff' than Ca|)ucine 
Orange, iii. , the eilge paler; Ochraceous Buff, xv. ; between Ocliraceous Buff and 
Ochraceous Orange, xv., darker in places; near Cinnamon, xxix., faded in parts; 
Light Ochraceous Salmon, xv., Light Vinaceous Cinnamon, xxix., to Pinkish 
Cinnamon, nearly Cinnamon), soft to the touch, vegetative stratum dense of 
closely felted mycelium about 0.7 to 1 mm. thick, texture somewhat X ylostroma- 
like margin sterile, narrow, dense, byssoid, paler. Tubes shallow, mostly 0.5 mm. 
deep, dissepiments very thin, irregular, edge setaceous, very irregular and 
laceiated, pores irregular, about 4 in 1 mm., very oljlique where the fruit body 
is not quite horizontal. When growing in very wet places it is often paler and 
tile sterile border wider. Tasmania. .Tanuary, May, July. 
307. Poria siibaurantiaca Rodw. et Clel. (Ij., subaurantiaous, somewhat 
orange). — Forming rather indeterminate patches, sometimes with an obtuse 
upturned margin, up to 7 x 5 cm. in size, of a pale dull oi-ange tint (Warm Buff', 
XV., to Ochraceous Buff', xv., or paler than Capucine Orange, ill., the ochraceous 
buff appearing on the under surface), rather soft to the touch, u)i to 4 mm. 
thick. Subiculum very tlnn, the total thickness composed chiefly of the ))ores 
which may be stratose. Pores oblique, about 3 in 1 mm., the orifices a little 
polygonal, dissepiments rather tliin, thicker when the tubes are very obliiiue. 
Tasmania. New Bouth Wales. March. 
368. Poria incrassata (B. et C.) Burt. (L., incrassatus, fattened, made 
stout). — This is a species causing a “dry rot” in the United States and 
considerable economic, loss in lumber and l>uililing wood. It is characteriseil 
by dusky-brown spores, 8 to 10 x (i.5 to 7 y. in size. The tiore-surface when 
formed cracks widely in drying and becomes brownish to blackish-brown, con- 
trasting with the broad sterile dirty-whitish, sometimes orange-tinted, margin.
