A large family of brown‑spored agarics characterised by the presence of a cortina—a fine, cobweb‑like partial veil that often leaves rusty‑brown fibrils or bands on the stipe as the spores mature. Fruitbodies range from small to robust, typically with dry to viscid caps, warm brown to ochre colours, and rust‑brown spore prints. Spores are usually ornamented, from finely verrucose to coarsely warty, and often dextri­noid in Melzer’s reagent. Lamellae are adnate to adnexed, becoming strongly rust‑brown with age as spores accumulate.

The family is ectomycorrhizal, forming symbioses with a wide range of hosts including Nothofagus, Leptospermum/Kunzea, Eucalyptus, and northern hemisphere conifers and hardwoods. Species occur in forests, shrublands, and montane habitats, often fruiting in autumn to early winter.

A southern-hemisphere genus of rust-brown–spored, cortina-bearing agarics segregated from the former broad Cortinarius. Species are typically medium- large sized, with dry to slightly viscid caps, warm brown, ochraceous, or tawny colours, and a persistent cortina that often leaves rusty fibrils or a faint annular zone on the stipe. Lamellae are adnate to adnexed, pale at first, then deep rust-brown as spores mature.

A genus of brightly coloured, cortina-bearing, rust-spored agarics, segregated from the former broad Cortinarius and defined by a well-supported molecular clade characterised by yellow to orange pigments, ornamented dextrinoid spores, and a persistent cortina. Species are typically medium-sized, with dry to viscid caps, warm yellow, orange, ochre, or tawny tones, and lamellae that become deep rust-brown as spores mature.

A genus of rust-brown–spored, cortina-bearing agarics, now much more narrowly defined following the 2022–2024 global revision of Cortinariaceae.

Phlegmacium comprises medium‑ to large‑sized agarics characterised by a viscid pileus, a dry to slightly viscid stipe, and a well‑developed universal veil that often leaves membranous or fibrillose patches, girdles, or a collar.

Thaxterogaster is a southern-hemisphere-rich genus of sequestrate and agaricoid ectomycorrhizal fungi formerly placed in Cortinarius. Species have brown, ornamented spores, white cortina remnants, and strong associations with Nothofagus and Myrtaceae. New Zealand hosts numerous undescribed taxa, many of which are agaricoid despite the genus being predominantly truffle-like worldwide.

These are fungi which have lost their ability to forcefully eject their spores. Instead, they rely on insects and birds to eat and carry them off for dispersal. Many are brightly coloured and found on or partially beried in the ground; some have a week stalk, while others have lost this.

Until recently, all the purple-pouch fungi were thought to be Cortinarius porphyroideus, until DNA sequencing showed this was not the case. This small group has been divided up into eight different species.

The fungi below are those that I have been unable to identify beyond their genus. Likely due to me not understanding the keys or a species that has not yet been described (named). Some have been sequenced, confirming that they are undescribed species.
