Resumo: 	Microscopic evidence confirms that L. cruciata hosting G. proliferum shows major anatomical traits (arbuscules, coils, arbusculate coils and vesicles) generally associated arbuscular mycorrhizal roots and the anatomical morphology of intra-thalli mycelium is predominantly of the Paris-type. Colonised L. cruciata showed a reduction of biomass when compared with axenic plants suggesting a drain of resources towards the fungus and depletion of nutrients required for optimum plant growth. The behaviour of mycothalli regarding available KH2PO4 indicates that the nutritional stress threshold for phosphorus (P) is above the residual amount of P already present in PhytagelTM and in plant inoculum. These raise the possibility that in certain circumstances the relationship between L. cruciata and G. proliferum be parasitic rather than symbiotic and open the door for future studies to ascertain the nature of liverwort-AM fungi relationships.
