Abrothallus halei is a species of lichenicolous fungus in the family Abrothallaceae.

[1] It was formally described as a new species in 2010 by lichenologists Sergio Pérez-Ortega, Ave Suija, David Leslie Hawksworth, and Rolf Santesson.

The type specimen was collected by Cliff Wetmore east of Hare Lake (Superior National Forest, Minnesota) at an elevation of 550 m (1,800 ft); there it was found on the foliose lichen Lobaria quercizans, which itself was growing on the bark of Acer saccharum.

[2] The fungus has also been collected in West Virginia, Maine, as well as in Norway.

[3] The species epithet honours American lichenologist Mason Hale.
