THE 1. AUGER FUNGI 
III. Stum firm, rigid, somewhat tough, juiceless, somewhat strigose and rooted 
at the base. Gills changing colour, white, then grey or reddish, commonly at 
length connected by veins. Pilous not liygrophanous. Generally lignicolous and 
caespitose. 
In the Mount Lofty Ranges, dense chimps of species of Myeena, dark-brown 
in colour-, eonioo-e.ampamilate in shape and with strigose hairs at the bases of 
the steins, may frequently be found on the trunks of stringy-bark Eucalypts, on 
stumps, on fallen logs, and on fence posts, often emerging from fissures in the 
wood. Their size doubtless depends to some extent on the weather and food 
conditions. These fungi vary a good deal in appearance, and probably several 
species are concerned. An attempt lias therefore been made to disentangle these 
supposed species, and the main points of difference have been set out in the 
Key just given. The first four species, namely M. subgalericulata , M. am- 
traMana, ^l . subnigHi, and M. euaalyptorum seem to lie the Australian represen- 
tatives of M. galencubita (Scop.) Fr. It is possible that, instead of being true 
species, they may merely show the variations that occur in a single unstable 
species, and if so the first name should apply to all. In any case, the descriptions 
indicate the range and nature of the variations in a closely related group of 
fungi. The next two speeies, .1/. irituweo-lufea and M. maeulata, present greater 
differences, though the latter may also he a member of the first-mentioned group 
showing a phase, the spotting of the gills, not' always present. 
6S. Myeena subgalericulata Clel. (L„ xubgalerietdatus, (in this case) close to 
the species M. galericvJata ) . — Pileus * to tin. (1.2 to 2.5 cm.), f, to Jin. (0.8 to 
1.8 cm.) high, eoiiico-canipamilate, somewhat expanding, umbonate, dry, smooth, 
subniembruiiaceons, somewhat striate to the umbo, near Olive Brown (XL.), 
occasionally paler (Butty Brown, XL.), sometimes Mummy Brown (xv.), during 
drying becoming paler from above from Olive Brown to Butty Brown, when young 
with a pallid peripheral ring. Gills adnate, sometimes with a slight decurreut 
tooth, sometimes connected by veins, whitish, sometimes flesh-tinted or greyish 
when old. Stem J to 2in. (1.8 to a cm.), often curved, smooth, polished, somewhat 
fragile to rather tough, base somewhat strigose, whitish to pallid, sometimes 
brownish, especially below. Shed spores elliptical, oblique, 9 to 13 x 5.5 to 
8.:i g. No oystidin seen. Xo smell. Caespitose on trunks. South Australia — - 
On trunks of Eucalyptus obliqua L' Merit, Mount Lofty; National Park. April 
to August. 
This is evidently a variable speeies. It differs from Rea’s description of 
Myeena galcneulata (Scop.) Fr. in being of smaller size, with the eap apparently 
darker, in the gills sometimes becoming greyish when old and in the stem often 
being nearly pure white. The characteristics of the species are the caespitose 
habit on trunks or stumps, the dark fuscous brown to pale smoky brown umbonate 
pileus, the gills adnate sometimes with a decurrent tooth and whitish becoming 
flesh-coloured or greyish and the whitish or pallid stem sometimes brownish 
below. 
69. Myeena australiana Clel. (L., AiwtraUwyu#, Australian). — Pileus fin. 
(1.2 cm.) high, Jin. (1.8 cm.) broad, broadly conieo-canipanulate, slightly striate, 
Butty Brown to Clove Brown (XL.) or Wood Brown (XL.), apex darker. Gills 
adnate, with no decurrent tooth, moderately close, pure white becoming creamy. 
Stem about 3.7 cm., slender, polished, a little mealy at the base but without 
strigose. hairs, apex whitish, Huffy Brown towards the base. Spores 8.5 to ill x 
6 to 7.5 p. Gregarious or caespitose on fallen logs. South Australia — National 
Park, Mount. Lofty. May to July. 
70. Myeena subnigra Clel. (L„ mbnigter, blackish). — Pileus up to Jin. (1.8 cm.) 
high and broad, eampanulate to eomeo-enmpamdat'e, smooth, faintly striate, 
nearly black to Mummy Brown (xv.) at edge. Gills adnate or ainuato-adnate 
with a decurreut tooth, moderately close, ventricose, greyish. Stem 2iu. (5 cm.) 
or more, slightly attenuated upwards, eoneolorous with the pileus above, pallid 
and densely strigose below. Spores 7..> to 1) x 4.5 to 5.5 g. Densely caespitose 
on stumps. South Australia — Mount Lofty, Caroline State Forest (R E.) Ma\ 
June. ' 
71. Myeena eucalyptorum Clel. (L.. here of Eiuuhiplus trees).— Pileus 1 to 
I [in. (2.5 to 3.1 cm.), broadly conical or conico-convex, expanding to convex, with 
a prominent obtuse umbo, smooth, periphery substriate, dark brownish grey (near 
chocolate colour), edge pallid. Gills sinuately adnexed sometimes to a collar, 
moderately close, narrow, greyish. Stem up to 2 Jin. (6.2 cm.), slender, hollow,
