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

Mycologia 102 (4): 871 (2010)

Type: Jaapia Bres. 1911

These are thin effused crusts found on wet decayed wood in humid habitats. Both species are rare. The genus is named after Otto Jaap, a German botanist (1864 - 1922). German primary school teacher and cryptogamist who collected a number of exsiccatae series of fungi. We have duplicate sets of his rust fungi exsiccatae at the Field Museum herbarium.

    • Jaapia argillacea USA: ID, MA, NC, NY; Canada: BC; Northern Europe (Type: Germany)
    • Jaapia ochroleuca USA: AZ, CA, MA, NC, OR; Europe, Russia (Type: Germany)
Taxonomy:
Previously placed in the Boletales but then shown by Binder et al. (2010) to be basal to the Agaricomycetidae (containing clades of Boletales-Atheliales and Agaricales-Amylocorticiales). But later Hibbett et al. (2014) state that Jaapiales is further removed and placed with Gloeophyllales and Corticiales.
