%X the cutter ants show preference for some vegetable species, which are constantly defoliated, while others are not attacked, although they are abundant and located close to the nest. the ants of the goods atta and acromyrmex cut plants and they transport pieces to the anthills. the vegetable material is used for the cultivation of the mushroom leucoagaricus gongylophorus, mushroom from of which theyfeed. several works using extracts of plants have been accomplished to evaluate the effect on the development of the mushroom symbiont. the objective of this work was to evaluate the influence of added culture means of different extracts on the growth of the l. gongylophorus mushroom. where mushrooms of the species acromyrmex ambiguus, acromyrmex crassispinus, acromyrmex heyeri and acromyrmex lundi were inoculated in the means nutritious ¨¢gar and bda, both added of molasses and extracts of lolium multiflorum lam., typha angustifolia l. and ant (atta sexdens piriventris). the pagnocca medium was used as pattern. the plates were maintained in cameras acclimatized to the temperature of 25 + 1¡ãc and 24 hours of darkness, for a period of 49 days. the fungal growth was evaluated with base in the diameter of the colony, which was accomplished with weekly intervals, totalizing seven evaluations. also the dry weight was evaluated from the mushroom to the 53 days. the results showed that the mushroom cultivated by different species of ants has differentiated growth in culture means with different extracts.
