AI-generated description

Dicarpella dryina is a species of fungus in the family Melanconidaceae, order Diaporthales, class Sordariomycetes, phylum Ascomycota. It is associated with canker disease on live oak and other Quercus species. In East and Central Texas, Dicarpella dryina has been found to infect trees, particularly those under stress, causing sunken cankers and dieback. The fungus produces conidia and ascospores, allowing it to spread and infect new hosts. It is considered a significant pathogen of oak trees in the region, contributing to decline and mortality.
