Description
''Eucalyptus guilfoylei'' is a tree that typically grows to a height of . It has rough, short-fibred, crumbly, greyish brown bark and a trunk diameter of about . Young plants and
coppice regrowth have stems that are more or less square in cross-section and leaves that are egg-shaped, dark green above and paler on the lower surface, long and wide. Adult leaves are lance-shaped, dull green on the upper surface, paler below, long and wide on a
petiole long. The flower buds are arranged in groups of seven on branching

The species was reported as occurring with several plant species, often as the understorey of the ''E. jacksonii'', which is distinguished by its larger size, more fibrous bark and the name red tingle tingle (a variation of a common name, as 'yellow tingle tingle', was also once in popular use for this species).

Uses
The heartwood is hard and straight-grained with an oak-like yellow colour. The wood has a green density of about 1185 kg/m3 and an air-dried density about 990 kg/m3.[
