Wilcoxina is a genus of fungi in the family Pyronemataceae.

It was circumscribed by Chin Yang and Richard Korf in 1985.

[1] Some species have been shown to produce the siderophore compound ferricrocin.

[2] Species are cosmopolitan in distribution, and have been found growing with host plants in a wide variety on environments, such as nursery soils with high pH, mining sites with low pH and heavy metal contamination, natural forests and plantations, urban areas and peat soils.

[3] Wilcoxina species are mycorrhizal, and commonly infect a variety of conifers and deciduous trees such as Pinus, Betula, and Quercus species.
