Hygrocybe miniata group, "Vermilion Waxcap", occurs worldwide, and is widespread in Australia, especially on the soil in heathlands, grass and wet forests, as groups or bunches. Bright red cap and stem, but gills often more yellowish shades. It has a waxy feel, with caps to 35 mm, slightly depressed, and gills distant, thick, waxy; spore print white. Stem smooth, no ring, yellowish near base. NB: There are several similar bright red Hygrocybe species, so I have called this a "group."

Hygrophoropsis aurantiaca, "False Chanterelle" is the suspected identity of this specimen. It occurs world-wide. Wikipedia ref Mushroom expert ref Mykoweb ref Eco Tourism track, Sanatorium Picnic Ground, Mt Macedon, 2008. 73 kB
Hyphodontia flaviporais a polypore-like wood-rotting parasite that is growing on a live eucalypt at this site. It forms multiple patches on the side of the tree, the pore surface consisting of coarse pale orange vertical tubes, with a ragged, tooth-like appearance. Ned's Gully, Cathedral Range, 2005. 81 kB
Hyphodontia australis is the most probable identity of this specimen. One of a series of wood-rotting fungi which form "paint-like" patches and sheets (i.e. corticioid) on rotting wood, this species forms felty layers, deep pinkish buff to orangish in colour. The fertile surface displays a maze-like cracked pattern with irregular toothy pimples. Occurs in Australia-NZ-Argentina in eucalypt and Nothofagus forests.

Hypholoma brunneum is a wood-rotting fungus grows on decaying wood usually in dense clumps, possibly only in Australia-NZ. It has a brown to dark brown cap, to 60 mm, with whitish scales towards the margin. The gills are yellowish to greenish, darkening as spores develop; spore print purple brown. The stem is fibrillose, especially towards the base, colour pallid to pale brown, with a fibrillose ring of fine veil remnants.

Hypholoma fasciculare, "Sulphur Tuft", is very common world-wide wood-rotting fungus found in close bunches (i.e. caespitose) on rotting logs and buried wood. Caps around 50 mm, smooth, not viscid, colour variable from yellow, greenish-yellow, orange-yellow, margin often lighter. Gills close, sulphur-yellow when young to greenish, then much darker purplish-brown to brown when older; spore print purple brown. Stem can be tall, yellowish, fibrillose, with fibrillose veil remnants in the upper third, darker near base. The whole appearance very variable. Bitter and poisonous. NB: There is a variant form with apricot gills. Wikipedia ref NZ Landcare ref Mushroom Expert ref Mortimer Picnic Ground, Bunyip State Forest, 2009. 102 kB
Hypholoma australe, "Brick Cap", has the same appearance as Hypholoma sublateritium, a Northern Hemisphere species, also found in Australia; they are distinguishable only microscopically. It is a wood-rotting fungus found on stumps, logs and buried wood, usually in clumps (i.e. caespitose). Cap brick red, to 55 mm or more, with white fibrillose scales towards the margin when young. Gills are yellowish green, darkening with age; spore print purple brown. Stem very fibrillose-scaly, with zones of gold and browns. NB: The following refs show the species H. sublateritium.

Hypocrea victoriensis, previously known by the Northern Hemisphere name Hypocrea sulphurea, forms patches or cushions of lemon yellow to ochre tissue up to 0.5 mm thick, on bare dead wood which is devoid of bark, with visible little dark spots, which are the ostioles, openings from which the ascospores are released. It is a wood-rotting ascomycete, and might even colonize certain other fungi. Doctor's Creek walking track, Reefton, 2009. 35 kB
Hypoxylon sp. aff. fuscum. Hypoxylon fuscum is a Northern Hemisphere species, which our local species closely resembles. It grows on bark or dead branches as purple brown cushions about 6 mm across, with tiny mounds (perithecia, 0.3 mm) on the surface, from which the spores are released. The cushions can merge into colonies. It is thought to infect live trees, then appear on the wood after it has been killed by the fungus. Pyrenomycetes ref Bioimages ref Doctor's Creek walking track, Reefton, 2009.
Hypoxylon rubiginosum group forms thin, brittle, often extensive purplish crusts on bare, dead wood. There are minute white dots which are the ostioles from which spores emerge. It occurs commonly worldwide and is a group of related species. It has been proposed that the name Annulohypoxylon placentiforme should be used for this one.
