As Agaricus praecox, in field, Napier, Colenso, b 283 and retained there by Horak (197ib) but we differ in our interpretation of the material. The basidiospores are metachromatic, dextrinoid (9.5-10.5 x 6 µm) and the cheilocystidia characterise a member of the L. naucina group. Parallel species are known from New Zealand and they may well have been introduced; they are generally more frequent in countries with warmer climates. A collection has been located in PDD (40317) filed under Armillaria.

Notes: Pholiota praecox (Fries) (6) = Agrocybe praecox (Fries) Fayod The collection (COLENSO b 283) contains a single, immature carpophore but all found characters correspond well with those of the type. It has probably been introduced from overseas.
