Lentinellus ursinus is an extremely variable fungus which appears to have a wide distribution in temperate
countries. The basidiomata may take up to 60 days
to mature and during this period they may change markedly in appearance,
particularly in the extent and nature of the hirsute covering of the pileus, and
internally, in the degree of development of amyloid hyphae (Miller &
Stewart 1971). It is not surprising, therefore, that this species has been described many
times under different names. Unfortunately, no holotype material of L.
ursinus appears to exist, but from a study of recognised synonyms a clear picture
emerges. Because of the confusion surrounding the Australian and New Zealand
records of this taxon, details of the relevant collections are given below.
