in 1958.
Phylogenetic analysis by Moncalvo (2002) and Bridge et al. (2008)has demonstrated the close relationship between Weraroa novae-zelandiae and the hallucinogenic blue-staining group of Psilocybe, particularly Psilocybe subaeruginosa
Psilocybe subaeruginosa

Borovička et al. (2010) suggest renaming the species Psilocybe weraroa. The specific epithet weraroa refers to the former generic name. The binomial Psilocybe novae-zelandiae could not be used, as it had already been used in 1978 by Gastón Guzmán

Description

  • Peridium: (1)3– 5 cm tall, 1.5– 3 cm wide, irregularly roundish to ovate, elliptical or even depressed-globose, margin folded, light brown when young becoming pale blue-grey, often showing blue or blue-green stains with age, at first finely fibrillose becoming smooth, glabrous, slightly viscid, bruising blue when injured, slowly. Drying dingy brown.
  • Gleba

    : Chocolate or sepia-brown, sparse, chambered, contorted gill-like structures.

    : Up to 4 cm tall, 6 mm thick, equal, cartilaginous, whitish to blue-grey, yellowish-brown at the base, hollow, bruising blue when injured.
  • Taste: Bitter-sweet, earthy flavor, released upon chewing of the raw fruit, probably not a taste sought after for culinary purposes.
  • Odor: Organic, similar to ferns, undertone of rubber.
  • Microscopic features: Oval Spores

. The pouch fungus has been found in winter in Central Hawkes Bay where they tend to be found around fallen pine cones - not in pine forests but in areas where pines are interspersed by other kinds of trees. They are also found on the south island. The mushroom is sometimes hard to see because its usually hidden under dried leaves. It is often eaten by slugs and sometimes hard to find specimens that haven't been nibbled on.
