Pileus/Cap: 10mm to 50mm in diameter, colour ranging from light golden brown to medium gray blue, conic to campanulate (cone-like to bell-shaped) with an inrolled margin, umbonate and often with an acute central papilla. It is transluscent-striate to the margin (fine radial lines are visible around the edge of the cap when moist), extremely hygrophanous, glabrous (smooth or free of ornamentation) and slightly fibrous. The flesh inside is firm and brownish orange to yellowish.

 

Lamellae/Gills: The gills are bare, pale grey to yellowish, thin and fairly close together, narrowly adnate (the gills meet the stipe by most of their width; they are broadly attached), with one or three short intermediate gills between two intermediate gills, and have a smooth edge.

​

Stipe/Stem: The stipe is 40–70 mm x 1-5 mm, pale greyish white, cylindrical, centered, fibrous, with brownish orange to yellowish flesh. It can be hollow or otherwise stuffed with fibres. The partial veil sometimes leaves a fragile line of raised threadlike tissue around the stipe close to half way down. This can resemble a faint, thin raised ring, often stained blue.

 

Bruising and spore print: Bruises blue when damaged or handled. This species has a very low spore production. Generally does not produce a spore print.

 

Distribution and habitat: Widespread throughout New Zealand. Fruits earlier in the season than other Psilocybe species, and has been known to fruit year round under the right conditions. Grows in potted plants from potting mix consisting of varying amounts of peat, decomposed Pinus radiata bark and pumice. Also found in landscaped gardens where these plants have been planted. Occasionally fruiting from rich soil in grassy areas. It is not common in heart wood chip unlike other wood loving species in this genus.

 

Comments: This species was first observed in New Zealand in 1969. It is known only from Taiwan and New Zealand.
