A. ilicinella resembles A. ilicina (described elsewhere); it is the least common of the two oceanic species with a narrower range of smooth-barked hosts. A. ilicinella grows mainly on hazel and has smaller discs (0.1-0.6mm diam. compared with 0.2-1mm diam.) and smaller spores (16-23ųm long compared with 26-36ųm long) than its relative. In Ireland, it is known from Counties Kerry and Donegal, but is easily overlooked in the field.

Key characteristics

  • Easily mistaken for A. ilicina which has larger discs and spores
  • Grows on hazel in the oceanic woods of the west.
