Three New Species of Mytilinidioid Fungi (Dothideomycetes, Ascomycota) from Mexico

Mytilinidioid fungi are conchiform in nature, with the appearance of bivalve shells or wedge-shaped, rigid, brittle, and carbonaceous hysterothecia growing on the bark of gymnosperms or angiosperms. Based on their morphological characteristics and molecular markers (<i>ITS</i> and <i>LSU</i>), this study describes three new species of mytilinidioid fungi: <i>Ericboehmia mexicana</i> of the family Hysteriaceae of the order Hysteriales and <i>Lophium pinicola</i> and <i>Mytilinidion mexicanum</i> of the family Mytilinidiaceae of the order Mytilinidiales. The first species grows on <i>Liquidambar styracyphlua</i>, the second species grows on <i>Pinus patula</i>, and the third species grows on <i>Acacia californica</i> subsp. <i>pringlei</i>. The specimens studied were deposited in the ENCB Herbarium.
