Hygrocybe boothii is a distinctive species, easy to identify in the field. Distribution is limited to a very small forest area undergoing rapid change. These forests have been exploited for timber and have from time to time been grazed by farm and feral animals, both of which can damage the habitat of Hygrocybe species.
Australia. Kooloomboola National Park in the Atherton Tablelands of North Queensland only.
Uncertain. This fungus was collected in the autumn of 2001 and 2002. There have been substantial increases in the sitings and collections of Hygrocybe species following the publication of Dr Young’s monograph on the genus in 2005, but that has not been the case for H. boothii.

Only occurs in areas of damp woodland in open forest on nutrient poor soils. This species was thought to be mycorrhizal but the biology of other species in this genus is known to be complex and is not yet well understood. It is thought that many Hygrocybes are biotrophic and may be associated with mosses (e.g. Halbwachs 2013).
This National Park was a Forest Reserve until 2010 and was commercially exploited for timber. The forest and the National Park were also subject to grazing and disturbance by farm animals and continue to be disturbed by feral animals, particularly wild pigs. As part of the management plan there are controlled burns undertaken on a rotational basis. Although this species is probably associated with damp hollows which the management plan seeks to exclude from the fire regime, it is not clear that this has been a successful policy. All these factors are known to affect the survival of Hygrocybe species in other localities.
None at present, this fungus is classified as ‘least concern’ under Queensland legislation. The sites for these fungi designated as a National Park in 2010 but there is no specific conservation management for fungi.
Work is needed to clarify the biology of this fungus including its fruiting patterns and habitat requirements.
