"Magic mushrooms" will be banned in the Netherlands from next week after a court ruling Friday, in the latest sign of a hardening stance on recreational drug use by the traditionally liberal Dutch.

The ban will be in place from Monday after the district court in The Hague rejected a petition by a body representing vendors of the hallucinogenic fungi to halt a health ministry ban on their cultivation and sale.

The ruling comes days after authorities ordered dozens of Amsterdam's famous cannabis-selling coffee shops to close and two other municipalities announced they would close down all their cannabis cafes from February.

"This is bad news for us," Paul van Oyen, a spokesman for the vendors' association VLOS told AFP after the verdict. "We are highly disappointed."

The district court dismissed the VLOS's petition for an urgent interdict against the ban as groundless and unfair.

The ban, introduced by Health Minister Ab Klink and already passed by lawmakers, will now come into force on December 1.

The legislation forbids both the cultivation and sale of fresh hallucinogenic mushrooms, which grow naturally in the wild in several areas.

A total of 186 species of "shrooms" or "paddos" will become illegal from Monday, with more expected to follow later. The dried variety has been illegal in the country for several years.

Klink believes consumption of the fungi, sold in the Netherlands in so-called smart shops, "can lead to unpredictable and risky behaviour".
