Laurisylve of the island of El Hierro: exclusive parasitic fungus on a Canary laurel (Laurobasidium lauri). This type of humid forest is present on very humid ridges subject to the trade winds, causing a "horizontal rain" of nearly 1500 mm/year and is dominated by lauraceae, ferns and mosses. Many of the species are endemic and the entire island of El Hierro is a UNESCO Biosphere Reserve.
