Epichloe typhina

Epichloë typhina is a haploid sexual species in the fungal genus Epichloë. It was originally described as a Sphaeria species. Today, however, it is classified in Epichloë. A systemic grass symbiont first described as Sphaeria typhina by Christian Hendrik Persoon in 1798, and transferred to genus Epichloë in 1865, E. typhina forms an only partially resolved species complex within the Epichloë genus. Epichloë typhina is found in Europe, but has been introduced widely in North America and elsewhere. It lives in association with a large number of grass species from multiple genera, including Anthoxanthum odoratum, Brachypodium phoenicoides, Brachypodium pinnatum, Dactylis glomerata, Lolium perenne, Milium effusum, Phleum pratense, Poa trivialis, Poa silvicola and Puccinellia distans. Epichloë typhina appears to be seed-transmissible only in Puccinellia distans....read more on Wikipedia.
