Descriptions
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.
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.
New Zealand: South Island: Otago: Makarora, Pipsen's Creek, 16.1V. 1965, leg. Taylor. 240 (holotype). -Canterbury: Lake Ohau, 9.V.1971, leg. Taylor. 676.
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.
