little darker, namely, Ocliraceous Tawny (xv.). Specimens from Dorrigo, New 
South Wales, identified by Lloyd, have a context near Sudan Brown (ill.) which 
is a little darker again and the same colour as Lloyd gives for F. senex Mont., 
which is placed under his subsection with dark brown context. The orifices of 
the pores of the Uorrigo specimens are 4 to 5 in 1 mm., whereas in our F. 
rimotius they are usually 2 to 3. The spores arc subspherical, dark brown, 4 to 
5 the setae acuminate with ililated bases, dark brown, 34 to 50 x 8.5 fx. The 
rimose appearance of the upper surface is not marked. 
A large distorted hoof-shaped specimen from Kuitpo, South Australia, October, 
Lloyd suggests may be F. Yuoatensiit. It has a dark lirown rimose upper surface, 
with a concave pore surface as in F. conchat-us, but is thick (4in. x 21in. thick x 
41in. high, 10 x 0.2 x 11.2 cm.). The context is near Sudan Brown (m.); the 
pore orifices 4 in 1 mm. ; spores subspherical to oval, white, slightly coloured or 
occasionally decidedly brown; setae acuminate, ventricose, sometimes stalked, 
brown. 
305. Femes senex Mont. (L., senex, old, wrinkleil). — C. G. Lloyd describes 
this species as being applanate, sometimes quite largo, with a brown rugulose 
surface without a distinct crust; the context Sudan Brown; the pore mouths very 
minute, darker Virown than the context, soft to the touch; setae very abundant, 
rather short and thick, 12 to 14 fi\ spores globose, deeply coloured probablj 
hyaline when young. Dr. G. 11. Cunningham recognises F. zelandicus Cooke with 
h'valine spores as distinct. Specimens from Invercargill, New Zealand, June, 
were identified by C. G. Lloyd as Polyporus forms of F. senex, though 
Cunningham considers them as F. zelandicus. I found the context near 
Ocliraceous Tawny (xv.), the pore surface near Cinnamon Brown (xv.), orifices 
about 5 in 1 mm., subspherical brown spores 4.8 x 3.2 fx, and numerous acuminate 
brown setae with ventricose bases, 24 to 32 x (i.5 to 8 /i. 
A description of F. senex is included here for comparison with Australian 
plants referred to F. Yucatensis. The chief iioints of difference seem to be the 
applanate shape of F. senex compared with the more or less hoof-shape of F. 
Yucatensis, the wrinkled surface of the formei' as against a rimose crust and 
the darker pore surface velutinate to the touch in F. senex. The context colour is 
also perhaiis darker in F. senex. 
306. Femes lividus Kalchb. (L., lividus, livid). — Forming extensive patches 
up to 20 X 9 cm., with the edge usually sharply defined. Pores minute, about 
0.16 mm. wide, about 6 in 1 imn., pore layer 3 to 7 mm. deep. Ilymenial surface 
when young near putty colour or greyer, or darker and greyer than fiesli colour; 
when older, becoming near Fuscous (XiA’ii.), passing into Drab (XLVi.), and 
thence to the paler edge; when very old, sometimes blackish fuscous on which 
fresh patches of the greyish putty-coloured younger growtli may appear. Tubes 
near Drab or darker or more fuscous than Natal Brown (XL.), sometimes showing 
grey tints. Context purplish fuscous, very thin, 1 to 1.5 mm., firm-floccose like 
compressed cotton-wool, sometimes appearing beyond the hymenial area as a 
dark livid brown scorched-looking sloping edge. Hyphae microscopically of a 
rather livid fuscous brown, a little Irregular, 2 to 5.5, usually about 3.5 fx, thick. 
Spores white, subspherical to irregularly oval or rather quadrilateral, 5 x 3.5 ix. 
Queenslan<l. New South Wales. Not yet recorded for South Australia. 
January to March, June, August to November. 
Our Australian specimens form effused drab to fuscous patches without any 
obvious bracket formation, thus resembling a Poria. A stratose arrangement of 
the tubes is not very obvious. 
307. Fomas hemitephrus Berk. (Gr., hemisus, half; tepkra, ashes, ))resumably 
from the upper surface having a cinereous tinge in places). — Pileus up to 4 to 
Sin. (10 to 12.5 cm.) or more laterally x 2Jin. (6.2 cm.), u|) to liin. (3.7 cm.) 
thick in the middle, dimidiate to hoof-shaped or sometimes as rather applanate 
brackets, more oi' less decurrent at the attachment and sometimes almost entirely 
decurrent, surface dull with a hard sublaccate crust, usuallv with a brownish- 
orange tint below the crust, somewhat concentrically sulcate and zoned towards 
the edge. Smoke Gray (XLVi.) and paler to Snuff Brown (xxix.) in the older 
portion, passing through Drab (xiiVl.) to dark brown (Bister, xxix.) towards 
the rounded edge. Pore surface and co.ntext Pinkish Buff to Cinnamon Buff 
(XXIX.); tubes up to 1.5 cm., imperfectly stratified; orifices very minute, about 
6 in 1 mm. Spores white. New South Wales. New' Zealand.
