285. Boletus liiridus (Sdiaeff.) Vv. (L., luridus, lurid in colour).— Pileus up 
to 4Jin. (10.() cm.), convex to subconvex, sligktly irregular, surface dull, smooth 
with a few adpressed librils, reddisli-brown. Tubes adnate or with a slight sulcus 
round the stem, slightly attenuated botli ways, fin. (6 mm.) lengthening to fin. 
(12 mm.), pallid yellowish-green becoming dark dingy green, oritices reddish. 
iSteni up to 21in. ((i.2 cm.), stout (llin., 3.5 cm.), when young swollen in the 
middle, sometimes nearly even, finely reticulated with raiseil reddish-brown lines, 
the interspaces yellowish, root conical. Flesh turning bluish, especiallv when 
young, reddisli-brown where insect-eaten. Spores mummv-sha))ed, brownish, 9.5 
to 14 X 4.8 to (i /J.. South Australia — Under Eucalyptus, Kuitpo. May. 
The species is characterised liy the reddish-brown pileus, the yellowish-green 
tubes with reddish orifices and the yellow stem reticulated with" reddish-brown 
veins. In British specimens the tubes are free. 
28(1. Boletus fuscus Clel. (L., fuscus, dark).— Pileus Sin. (7.5 cm.), convex, 
very viscid, dark-brown near chocolate. Tubes lin. (1.2 cm.) deep, old gold in 
colour, dingy dark-greenish when bniised, orifices moderately large, irregular. 
Stem 2iin. (fi.2 cm.), stout (iiin., 1.8 cm.), reticulate above, rather punctate 
below, solid, dark sooty brown. Tubes turning bluev-green when cut, the colour 
extending a little into^ the adjacent flesh, the rest of the flesh of the pileus ami 
that of the stem whitish with brownish tints. Spores mummv-.shaped, dingy 
pallid brown, 9 to 10 x 3.7 to 5 fi. Under shrubs, etc. South Australia— Mount 
Lofty. 
287. Boletus erythropus (Pers.) Quel. (Gr., erythros, red; pmts, a foot).— 
Pileus 2 to 3iin. (5 to 8.7 cm.), convex, fibrillose-matt or felted with low 
irregular ridges, near Maroon and Victoria Lake (l.) or darker than Buffy 
Brown (xl. ) with vinaceous tints. Hymenial surface convex with a deep broad 
sulcus round the stem, tubes adnexed with a trace of decurrence, up to 4 m. 
(1.8 cm.) deep, near Aniline Yellow (iv.) or Honey Yellow (xcx.), turning 
greenish-yellow, orifices minute, crimson or turning reddish. Stem IJ to 3in. 
(3.7 to 7.5 cm.), equal but a little conical at the root, tliiek (lin., 2.5 cm.), not 
reticulated, flbrillose, punctate witli maroon on an old gold base or mottled

Willunga Hill. May to June. 
Characterised by the yellow tubes with red orifices, the yellow stem punctate 
with red and tlie fibriliose-matt, not viscid, cap. Our Australian plants with 
yellow tubes and red orifices slu^w variation as to tlie red points on the usually 
yellow stem and in the colour of the flesh liut are probably best considered as 
all forms of the European B. erythropus. 
288. Boletus granulatus (L.) Fr. (L., gramdatus, granulated, from the 
granules left round the orifices of the tubes from the drying of a whitish milk 
dripping from the pores when young — a feature not hitherto noticed in Austra- 
lian specimens). — Pileus 2-1 to 4in. (0.2 to 10 cm.) or more, viscid to very viscid 
when moist, soft to the touch when dry, irregularly convex, sometimes depressed

Tawny (xv.). Tubes with a slight sulcus round the stem, up to -Hn. (1.2 cm.) 
deep, attenuated externally and internally, orifices about 1 mm. diameter, dis-, 
sepiments thin, when j'oung Deep Colonial Buff (xxx.) or Mustard Yellow to 
Wax Yellow (xvi.)', when older between Old Gold (xvi.) and Orange Citrine 
(IV.). Stem 1| to 21in. (4.4 to (i.2 cm.), stout (1.5 cm.) to slender (8 mm.),

Vinaceous (xxxix.) at the ba.se. Smell slight. Flesh soft, pale yellow to

ground, always under or near species of Pinus. South Australia — Adelaide, 
National Park, Encounter Bay, Basket Range. Nelw South Wales. May. 
(Figure 40.) 
This is a very common species never found except near Pinus. It is readily 
recognised by its glutinous cap (when moist) wliicli is brown and somewhat like 
a yeast bun, its pure yellow tubes becoming old gold in colour, the dark granules
