COMMENTS

Hürlimann (1998) mentions New Caledonia as part of the range of this species, likely followingParis (1908) who reports a specimen of Chiloscyphus jackii Steph. collected by Le Rat, also reported by Miller et al. (1983). In G, only one specimen collected in New Caledonia by Le Rat is labelled Chiloscyphus jackii by Stephani. This specimen turned to be Heteroscyphus argutus . In the herbarium of E. G. Paris (REN), a duplicate of the original sent to Stephani has the same misidentification. All the Hürlimann’s specimens in G are from Tonga. As the only voucher from New Caledonia is not this species, Heteroscyphus jackii must be removed from the New Caledonian flora.
