[automatically translated] In 1902, Ferdinand Alfonso Spain, director of the Agricultural Institute Castelnuovo and editor of the New Annals of Agriculture Sicily, is the author of a publication entitled "Of the poisonous mushrooms" (1) which includes a "detailed list of the most common edible mushrooms" in order to provide useful information to mushroom hunters, and to avoid the frequent poisonings that, at that time, had caused many victims in various regions of Italy. Alfonso Spain, between species edible and good organoleptic properties, reports Pleurotus nebrodensis [sub: Agaricus nebrodensis Inz.], "Excellent quality mushroom", known locally as the "basilisk mushroom". Unlike Joseph Inzenga, that in the Centuries (2), had provided general information about the places of collection of the renowned madonita fungus, Alfonso Spain, in addition to providing interesting data on the abundance of fruiting, it indicates precisely two sites where he collects the fungus. In particular the towns he surveyed fell in the feuds of the cane and the Dragonara owned by the heirs of Baron Nicolò Turrisi Colonna. The possibility of basidiomi in these places collection is rather limited today because, due to the considerable human pressure, the population is in decline. The indication of Alfonso Spain on the abundance of its collected at the beginning of '900 is further confirmation of how the natural production of P. nebrodensis basidiomi has progressively contracted in the course of the years. Also an indication of the two collection locations allows you to put order in generic, and sometimes, confusing or incorrect signals reported in the literature. The two locations reported by Alfonso Spain were subject to verification in order to highlight the presence or the eventual extinction of the rare basidiomycete. In the light of the observations made you can confirm the presence of P. nebrodensis in former feuds of Canna and Dragonara, falling within the municipality of Petralia Sottana, although, as noted, in amounts undoubtedly lower than those given more than a century ago. The two locations, represented by extensive pastures in Cachrys ferulacea (L.) Calestani, have been for years the subject of intense exploitation for herding and, after imposition of the Madonie Regional Park, in 1989, they received more protection . This has not stopped the mushroom seekers,
