THE EAKGEK FUNGI 
375. Poria selecta Karst. (L., sdectu.% choice, select). — Forming irregular 
patches, 10 x 2 cm. in size, near Pinkish Buff (xxi.x.) or greyer, semi-detachable, 
with a broad irregular indeterminate felted-tlutly nearly whitish margin, very 
thin, rarely nearly 1 mm. thick, pores about 0.25 mm. deep, orifices variable, 
somewliat 'anguhwy 0.1 to 0..32 mm. wide, 3 to 5 in 1 mm., dissepiments thin, 
smooth. Spores 5.5 x 2 /i. ITyphae se])tate, irregular, sometimes varicose, 
bi'anching at right angles, 2.5 to 4, rarely 7, wide. South Australia Near 
Ashbourne, Mount Lofty. New South Wales. Tasmania. February, April, May, 
.1 uly, August. 
There is doubt a(S to the correct identification of this variable species, some 
specimens of which seem to grade into Irpex obliqnufi. 
370. Poria minu.tipora Rodw. et Clel. (L., mhmUin, diminished, minute; Gr., 
poros, a pore). — Forming extensive patches up to 10 x 5 cm. or more, more dingy 
and in places darker than Pinkish Buft’ (xxix.) witli a sheen, rather silky-soft 
to the touch, 1 mm. thick, consisting cliiefly of the pores with a thin layer of 
white byasoid subiculum, indeterminate, with in parts a narrow or more extensive 
sterile byasoid or ()uite smooth white edge. Pores 0.7 mm. deep, orifices 0.1 mm. 
diameter, 7 in 1 mm., dissepiments thin, rounded, edges tending to be setose or 
jagged. Hyphae 2 to 3 m thick, rather irregular, white. New South Wales. 
Tasmania. Not yet recorded for South Australia. 
377. Poria carneo-lutea Eodw. et Clel. (L., carnms, flesh-coloured; Mms, pale 
yellow). — Irregularly effused forming ;i thin crust-like layer, not readily 
sej)arable. Pinkish Butt' (xxix.), the growing edge narrow, of the same colour 
or a little paler and finely pilose, up to 1 mm. thick, corky to subfriable, tending 
to crack, j)ores 0.5 mm. deej), orifices 0.1 to 0.32 mm. wide, usually under 0.24 
mm., 4 to 5 in 1 mm., the edges pilose and not I'agged, dissepiments rounded and 
0.05 to 0.1 mm. thick, substratum almost negligible, spores not seen, hyphae 
faintly tinted yellowish, rather irregular, 2 to 3.7 fi. New South Wales. Not yet 
recorded for South Australia. 
378. Poria hyalina Berk. (Gr., hpalos, a clear transparent stone, glass). — A 
specimen from Orange, New South Wales, identified by Miss E. M. Wakefield 
of the Royal Botanic Gardens, Kew, forms a somewhat circumscribed thin 
patch with an indefinite edge, l>etween Clay Colour and Tawny Olive (xxix.), in 
places darker than the latter, composed of the very small obliquely set pores 
presenting a somewhat translucent aji})earance (like dried gristle) resting on a 
very thin whitish subiculum. The surfiwe temls to split. The thickness is about 
I mm. The orifices are closely set, about (i in 1 mm., with thin dissepiments. 
Hyphae nearly colourless, 2 to (usually) 3.7, occasionally 4.2 g, calibre a little 
irregular. Houth Australian specimens referred to this species agree in the 
minuteness of the pore orifices and a sub-hyaline appearance of the pore surface 
but present a deej)er colour (ochraceous buff, cinnamon buff). Specimens from 
Kuitpo form small patches about 2.5 x t.5 cm. in size, with pallid felted edges 
contrasting with the pore-be:iring surface which is between Ochraceous Buff and 
Ochraceous Orange (xv.), later approaching Ochraceous Tawny (xv.). Tubes 
about 1 mm. deep, forming most of the thickness, orifices about 0.1 mm. wide, 
about 9 in 1 mm., honeycomb-like and rather polygonal, sometimes fluted, dis- 
sepiments very thin. South .Australia — Kuityio, Coi'omandel Valley, Mount Lofty, 
Mount MacIntyre (S.E.). New South Wales. Tasmania. May, June, October 
to December. 
379. Poria calcea Berk, et Br. (L., calx, calcis, a chalk stone). — Forming 
extensive hard but brittle patches, up to 20 x S cm. in size. Light Buff (xv.) or 
a little darker in colour, rather than "chalky white,’’ un<ler 0.5 to 1 mm. thick, 
densely adherent to the substratum. The pores are veiy' minute, usuallv about 
() in 1 mm., 0.174 to 0.2(50 mm. in diameter, and very shallow, the orifices rather 
polygonal and the dissepiments very thin. When develo])ed, the pores may form 
about lialf of the total thickness, but even in large patches are often not much 
more tlian raised reticulations, witli tlie dissepiments occasionally defective. On 
dead decaying wood, sometimes penetrating through thin superficial layers, and 
appearing below', wliere separation occurs, as a tenuous pallid indeterminate film 
on w'hich the minute spores soon ay)])ear. Hyphae wliite, in short lengths, slender, 
1.5 to 2.5 fi. Queensland. New' South Wales. Not yet recorded for South 
Australia.
