Assessment Notes


Lactifluus igniculus is part of a species complex with L. pulchrellus, both of which have only been recorded rarely.  Lactifluus igniculus is known from only the type locality in Vietnam in mixed forest.  Due to the small number of records, and possible confusion with L. pulchrellus, the species is assessed as Data Deficient.

Taxonomic notes

Lactifluus igniculus is a distinctive species owing to its pleurotoid basidiomata arising from white subiculum in combination with bright reddish orange colouration of pileus and stipe. The presence of thick-walled hairs and spores ornamented with rather long warts and incomplete reticulum is very characteristic. By these features
and also by the brownish discolouration of the milk it resembles
Lactarius brunellus from Guyana (Miller et al., 2002). However, Lactifluus igniculus differs from L. brunellus in a brighter colour of the basidiomata, in almost central position of the stipe, in more developed reticulum of the spore ornamentation and in shorter hairs in the stipitipellis. It is part of a morpohologically similar complex with L. pulchrellus.

Why suggested for a Global Red List Assessment?

The species is known only from the type locality. It was founded once 10 years ago in the rare type of moist tropical mountain evergreen forest.

Geographic range

The species is known only from the type locality in Vietnam in the Bidoup-Nui Ba National Park (Central Highland of Vietnam) in 2010.

Population and Trends

The species is known only from the type specimen.

Population Trend: Uncertain
