Ochroconis lascauxensis is a species of fungus of the Ascomycota phylum that was officially described in May 2012. The organism was obtained and isolated from Lascaux Cave in France, where it had begun appearing on the Paleolithic cave paintings on the walls of the cave. Along with the discovery of Ochroconis lascauxensis, the closely related Ochroconis anomala was also discovered on the paintings. The black stains that they caused first began being observed in 2001 and spread so far that they were considered to be a large concern by 2007.[1]
Along with its sibling species, Ochroconis lascauxensis was selected on May 22, 2013, by the International Institute for Species Exploration, located at Arizona State University, as one of the "Top 10 New Species" that had been discovered in 2012. The winners were selected from among a pool of more than 140 nominees. The two fungi were chosen because of their importance in relation to properly conserving the cave painting at Lascaux.[2]
After first being observed in the early 2000s, a number of treatments involving biocides were conducted to try to remove the fungal species, though they ultimately proved ineffective. The species was identified by using a genomic DNA study to compare its genetic structure to those of other species within the genus Ochroconis. Once confirmed, a method using a PCR assay was done to determine how extensive the species had spread throughout the cave system. It was ultimately determined that Ochroconis lascauxensis was to be found in every cave compartment within Lascaux Cave.[3]
A biocide treatment was attempted, involving benzalkonium chloride, miristalkonium chloride, and 2-octyl-2H-isothiazole-3-one, which resulted in a net decrease of fifty percent of the fungus in the caves, but it was noted that those left had a significant increase in their diversity.[4]

Ochroconis lascauxensis est une espèce de champignons de la division des Ascomycètes (Ascomycota), décrite officiellement en mai 2012.
L'organisme a été obtenu et isolé de la grotte de Lascaux en France, où il était apparu sur les parois de la grotte couverte de peintures rupestres du Paléolithique. Ochroconis anomala, un organisme étroitement lié à Ochroconis lascauxensis y a également été découvert. Les taches noires provoquées par cet organisme ont été observées pour la première fois en 2001 et se propagent si rapidement qu'elles sont considérées comme très préoccupantes depuis 2007.
Avec son espèce jumelle, Ochroconis lascauxensis a été sélectionnée le 22 mai 2013 par l'Institut international pour l'exploration des espèces, de l'université d'État de l'Arizona, pour faire partie du « Top 10 des nouvelles espèces » décrites en 2012. Les lauréats ont été choisis parmi plus de 140 espèces, elle-même faisant partie des quelque 18 000 espèces découvertes dans l'année. Les deux champignons ont été choisis en raison de leur implication pour la conservation des peintures de la grotte de Lascaux.
