Interpretive Summary: Fungi cause serious diseases of agricultural and forest crops. One group of fungi known as smut fungi causes diseases in plants by killing leaf, stem or seed tissue and replacing the tissue with dark powdery spores. Because many species of these fungi resemble each other superficially, species infecting wild plants and weeds can easily be confused with species infecting agricultural crops. Distinguishing these fungi is essential for identifying and controlling diseases. In this paper the smut fungi from an ornamental plant and herb related to celery and carrots were studied using microscopic structures and molecular sequences. It was determined that some isolates represented four new species that are described and illustrated. This research will be used by pathologists and plant disease diagnosticians to accurately identify these disease-causing fungi.
Technical Abstract: The genus Entyloma consists of more than 160 species of smut fungi distributed worldwide on dicots with Apiaceae being one of the main host families. This study aims to clarify the systematics and phylogeny of Entyloma on Eryngium (Apiaceae) with molecular and morphological data. Eleven species from Eryngium are discussed herein. Four of them are described as new taxa: E. carmeli sp. nov. on Eryngium falcatum, E. eryngii-cretici sp. nov. on Eryngium creticum, E. eryngii-maritimi sp. nov. on Eryngium maritimum and E. ho-chunkii sp. nov. on Eryngium yuccifolium. Analysis of the ITS region of rDNA is presented and supports the polyphyly of Entyloma on Eryngium. Within the Entyloma on Apiaceae a monophyletic group of species with anamorphs is observed, suggesting that the anamorph is a taxonomically important character for delimitation of species of Entyloma.
