Pluteus observed in the Mangemangeroa Reserve - published as Pluteus hubregtseorum f. horakianus

From Biota of NZ - Pluteus hubregtseorum f. horakianus is considered a synonym of Pluteus minor G. Stev. (1962), see https://biotanz.landcareresearch.co.nz/scientific-names/6b8dffa1-7708-41cd-adc6-7ae8e87e477e.

This species is one of the more variable Pluteus species in both colour, size and shape. All have a velvety cap with pigmented squamules in various shades of brown more or less evenly covering the entire cap surface. The cap shape is typically convex to hemispherical but may expand to become flattish. Microscopically all variations have clavate cap terminal cells and clavate caulocystidia.

cf. Horak's interpretation of Pluteus minor. Horak describes the cap of Pluteus minor as pale brown or brown without the distinctive net-like pattern as seen in Pluteus readiarum. Microscopically he describes the cells of the pileipellis and caulocystidia as distinctly clavate.

Description: The cap of this Pluteus is evenly covered with squamules which are light brown, brown or tan in colour. It has been observed growing up to 5 cm in diameter. There may be some wrinkling in the centre of the cap and the margin of the cap is typically marked with striations. The gills are cream-pink. The stipe is white-cream in colour becoming more yellow to tan with age and it is pruinose with a light powdery covering.

Abundance: Frequently observed in the Mangemangeroa Reserve.
