Lichenized fungi are a part of lichen symbiotic associations, in which a fungus and a
microalgae or cyanobacteria form a mutually beneficial relationship. This relationship allows
lichenized fungi to thrive in a wide range of environments, including extreme conditions such as
deserts and high altitudes. Due to their sensibility to atmospheric pollutants and their ability to
absorb and retain metallic elements, they have been used as bioindicators of the ecosistem health.
Despite their ecological significance, little is known about the species diversity of lichenized fungi
in certain regions of México, such as the state of Sinaloa. In this study, a directed sampling was
performed in “El Maviri” beach, located in the municipality of Ahome, Sinaloa, in which five
lichen morphotypes were obtained. For their identification, their DNA was extracted through the
CTAB method, the ITS region was amplified and a phylogenetic analysis was performed using the
Maximum Likelihood method. In the analysis, three samples were identified as Ramalina sp.,
where two of them formed a sister clade with R. complanata and one with R. stenospora. On the
other hand, one sample was identified as Dirinaria consimilis, while the last sample was identified
as Lecanora sp., which formed a sister clade with L. argopholis. These findings emphasize the
importance of “El Maviri” beach as a habitat for lichen diversity. Further studies should be
conducted to explore the potential ecological roles of these lichen species and to assess their
potential for medicinal or other practical uses.
Keywords: Lichenized fungi, molecular identification, Ramalina, Dirinaria, Lecanora.
