Researchers studying fungal diversity in Thailand discovered two entirely new types of fungi living on Dipterocarpaceae trees, which are economically important trees that produce lumber and resin. Using a combination of microscopic examination and DNA analysis, they identified and named these new fungi as Pulvinaticonidioma hyalinum and Subellipsoidispora guttulata. This discovery suggests that many more fungal species remain unknown, especially on plants that haven’t been extensively studied for their fungal communities.
