Alectoria imshaugii, commonly known as spiny witches hair,[1] is a species of fruticose lichen in the family Parmeliaceae that occurs in North America. It was described as a new species by the lichenologists Irwin Brodo and David L. Hawksworth in their 1977 monograph on the genus Alectoria. The species epithet honors Henry Andrew Imshaug.[2] The variety venezuelensis, proposed in 1994, occurs in Venezuela.[3]

The Chinese species Alectoria spiculatosa is somewhat similar in appearance to A. imshaugii, but is distinguished by its characteristic sorediate pseudocyphellae and also by having spinules that grow over soralia.[4]
