Pluteus observed in the Mangemangeroa Reserve - Pluteus sp. (cf. decoloratus)

Horak describes Pluteus decoloratus from a South Island observation and this creamy species that I observe may be a different species.

The light colour of the cap of this species distinguishes it in the field from other species although the cap colour can range through to light tan which can be more difficult to recognise. Microscopically the most distinctive character is the shape of the pileipellis cap cells. Pleurocystidia can be plentiful or difficult to find. Where present they are thin-walled and typically utriform in shape. “Pinhead, capitate, finger-like or lobate projections" have been observed (as described by Horak under Pluteus readiarum).

The fruit bodies of this species are typically about 3 cm in diameter but can be up to 6 cm. The cap is light cream-pink in colour, usually with only a hint of tan colour but at times with a tan centre, occasionally they can appear light tan, generally in wet conditions. The gills are cream-pink in colour with a concolorous gill edge and the stipe is also cream.

Abundance: Commonly observed in the Mangemangeroa Reserve.
