The main objective of this study was to identify mycorrhizal fungi from orchids of the genera Dracula and Epidendrum by means of morphological and molecular techniques, for which mycorrhizal fungi from root samples of 17 species of orchids, 9 species of the genus Dracula and 8 of the genus Epidendrum were isolated in a PDA culture medium, by means of the Screening technique, which were used in identification studies; The mycorrhizal fungus species isolated by means of the observation of their morphology and molecular analysis of the ITS sequences, with which it was possible to study the relation that exists with each species of orchid studied. With the help of the Blast computer tool, 19 Ascomiceto-edged fungi, 1 Basidiomiceto-edged fungus and two non-taxonomically classified fungi were identified. Finally, the mycorrhizal fungi were subjected to cellulose degradation tests using the DNS method in order to know if the isolated species could degrade organic matter and thus provide the necessary nutrients to the orchid species with whom they are related. The species Cantharellales sp. stands out as the strain with the greatest capacity to split organic matter.
