Study of lichen those develop on the construction rocks of Chellah site, historical monument of Rabat (Morocco), we had the opportunity to encounter two types of lichens. Surface lichens, altering slightly the material are represented by Collema crispum, Roccella phycopsis, Xanthoria calcicola and Xanthoria ectaneoides. Encrusting lichen, known as major agents of bio deterioration of building materials, are also represented by six species: Aspicilia calcarea, Verrucaria nigrescens Toninia aromatica, Verrucaria calciseda (Bagliettoa calciseda) and Placidum squamulosum, Lecania spadicea. The importance of lichens, among other agents, in the deterioration of building stone monuments was discussed in this study.

Abstract: (french)
L'étude des lichens qui se développent sur les pierres de construction du site de Chellah, monument historique de Rabat (Maroc), nous a permis de rencontrer deux types de lichens. Les lichens de surface, qui altèrent peu le matériau, sont représentés par Collema crispum, Roccella phycopsis, Xanthoria calcicola et Xanthoria ectaneoides. Les lichens encroûtants, connus comme agents important de bio détérioration des matériaux de construction, sont représentés également par six espèces : Aspicilia calcarea, Verrucaria nigrescens, Toninia aromatica, Verrucaria calciseda (Bagliettoa calciseda) et Placidum squamulosum, Lecania spadicea. L'importance des lichens, parmi d'autres agents, dans la détérioration de la pierre de construction des monuments a été discutée dans cette étude.
Author Keywords: Maroc, Chellah, lichens, monument, altération.
