Family Jaapiaceae Manfr. Binder, K.H. Larss. & Hibbett

This small family has one genus and two known species. These are thin effused crusts found on wet decayed wood in humid habitats. Both species are rare. The long fusiform spores are characteristic. In Jaapia argillacea an inner spore wall forms and the ends of the spores become empty.
