In New Zealand, Rozites castanella is by far the most common species of Rozites. This agaric is well distinguished by its chestnut-brown, glutinous pileus and the often-marginate bulb at the base of the stipe. Microscopically R. castanella is separated from the other New Zealand taxa by the rather small, elliptical spores.

In the field old and degraded basidiomes of R. castanella can be taken for Descolea majestalica Horak (1971b) whose glutinous pilei, however, never show the same conspicuous rust-brown colour seen in the former species.

In New Zealand's Nothofagus forests, Routes fusipes fruits preferentially among deep moss in damp localities. The long and tapering stipe makes this species well adapted to such sites. The non-striate annulus of R. fusipes is often ruptured or may fall off, so that in the field the generic identification of this taxon can be difficult.

Using the pertinent key for the identification of New Zealand's agaricaceous genera (Horak 1971a), Rozites meleagris is likely not to be recognised as a member of Rozites. Contrary to the majority of described taxa in Rozites, this species is characterised by deep lilac lamellae which gradually turn rust-brown. The lilac tint, however, is always recognised in the context of the stipe even in overmature basidiomes. In the field R. meleagris is readily identified by the strongly developed and persistent veil remnants (velum universale) that give the surface of the pileus a characteristic speckled appearance strongly reminiscent of a starling's winter plumage.
Typus PDD 27164.

The most distinctive feature of Rozites pallida is (as the name indicates) the pallid pileus, which in fresh condition is covered by a thick glutinous layer with embedded white squamules of the universal veil. Macroscopically this New Zealand species resembles R. sarmienti (Speg.) Horak (1979) which is common in the South American Nothofagus forests both in Chile and Argentina.

As far as is known. Rozites rugosiceps is found only in the South Island of New Zealand. As indicated in the key, this agaric is readily recognised by the rugose to strongly wrinkled surface of the pileus. The coarsely waited, amygdaliform spores and the conspicuous cheilocystidia are further distinctive features of this species.
