They seem young
Cantharellus has been suggested to me. Uncertain.
I haven't tried for a precise identification because I don't know which of the particular ones that were suggested are found in Australia. I know very little about different types of fungi. Suggestions please!
Medium single bolete growing from soil under cattle gate on track. Cap buff-coloured with very dark brown tufts. Not showing its pores yet. Stem stout, longitudinally textured, buff at the top going to very dark brown at the base.
Very tiny mushrooms growing out of fallen leaf. Caps buff/pale fawn, centrally indented, tuberculate, plicate, wider than high. Gills few, about 9, forming chambers and attaching to a collar around the stem, whitish. Stems maroon-black, very thin, wiry.
