Fruitbodies large at maturity, with distinct ring and pinkish/violaceous brown spores. With tea-tree but also recorded under beech. (Species similar to Cortinarius australiensis with mustard spores). |

H. aminophilum |
11’ |
Not associated with animal carcasses, stipe enlarged at base or not, pleurocystidia absent, cheilocystidia abundant. |
12 |
12 |
With beech. Stipe cylindrical. Pileus brown. Spores 9.5-11.5 x 6-7um |
H. mediorufum |
12’ |
With tea-tree. Stipe enlarged at base. Pileus paler cream/brown. Spores 8-10 x 5.5-6um |
H. lacteocoffeatum |
H. sacchariolens – Populus, Quercus, Tilia, Leptospermum (planted)
H. mesophaeum – Salix, Nothofagus (planted)
H. velutipes – Pinus, Nothofagus (not planted)
H. crustiliniforme – Betula, Cedrus, Fagus
H. aanenii – Salix (possibly upland)
H. hiemale – Salix, Pinus
H. cavipes – Populus, Betula
H. rostratum - Salix
H. pseudofragilipes – Salix, Quercus, Tilia
H. ammophilum- has been recorded with Leptospermum, Nothofagus (Sagara unpublished) and one record under Pinus (Leonard). This latter record has been confirmed by sequence data.

Thank you Jerry!
I think that is covered by 'With tea-tree but also recorded under beech'
Thanks Jerry this is very useful
