Neotyphodium australiense is a systemic and seed-transmissible symbiont of Echinopogon ovatus, a grass endemic to Australia and New Zealand / Aotearoa. To date, N. australiense has only been found in some Australian populations of this grass, whereas other populations in Australia and New Zealand have Neotyphodium aotearoae

Neotyphodium aotearoae

Neotyphodium aotearoae is a systemic and seed-transmissible symbiont of Echinopogon ovatus, a grass endemic to Australia and New Zealand. The fungus produces the anti-insect loline alkaloids. Unlike most Neotyphodium species, N. aotearoae does not appear to be a hybrid. Its closest...

. Molecular phylogenetic analysis indicates that N. australiense is an interspecific hybrid, and that its closest teleomorphic (sexual) relatives are Epichloë

Epichloë
