Endophytic Xenodidymella from Iranian medicinal plants: description of three novel species and a new host record.

Medicinal Plants
Fungi living invisibly inside your garden thyme and sage may be quietly protecting them from disease rather than causing it — flipping what we thought we knew about a whole group of plant fungi.
Researchers were studying the fungi hiding inside the tissues of wild medicinal plants in Iran and found three kinds nobody had ever described before. These fungi weren't making the plants sick — they were just living there peacefully, which is unusual since their relatives are known troublemakers that cause plant diseases. Finding them in healthy plants suggests this whole family of fungi might have a hidden, helpful side we've overlooked.
Key Findings
Three new Xenodidymella fungal species were discovered living asymptomatically inside Euphorbia (spurge) and Thymus (thyme) plants in Iran.
Xenodidymella camporesii was recorded for the first time on a new host plant, Salvia sclarea (clary sage), expanding the known range of this species.
Phylogenetic analysis using three gene regions confirmed each new species as genetically distinct, well-separated from all previously known relatives.

Scientists in Iran discovered three new species of a fungal genus (Xenodidymella) living harmlessly inside medicinal plants like thyme and spurge, suggesting these fungi may be beneficial partners rather than the pathogens they were previously known as.
