Rozites
Notes
Spore print rusty brown. Cap about 5-10 cm diam., typically sticky or glutinous, with irregular, scale-like patches, often striate near the margin; stalk with a well-developed, persistent, striate ring.
Molecular studies have shown that the characters used to recognise
Rozites
(glutinous cap and striate ring) have evolved indepently several times. Most New Zealand species of
Rozites
have now been placed in a very broadly-defined
Cortinarius
.
Like all
Cortinarius
species,
Rozites
is ectomycorrhizal, mostly under
Nothofagus
, but
R. australiensis
(=
Cortinarius australiensis
) is found under tea tree.
Rozites
can be confused with
Descolea
- also mycorrhizal under
Nothofagus
and tea tree and also with a persistent, striate ring on the stalk.
Descolea
differs in microscopic characters, and most species are smaller than
Rozites
, and they typically have a dry cap.
