Physodermatacae is a family of chytrid fungi in the order Physodermatales.

This family is distinctive in that it contains a thick wall around the sporangia to resist against unfavorable conditions.

[2] Sporangia releases from a host plant when rotting, dispersal is carried through the air.

[3] This family is not to be confused or related to basidiomycetes rusts and smut fungi.

[4] Physodermatacae breaks into two distinguished clades: Physoderma and Urophlyctis, which are grouped together because of the similar algal parasite called Paraphysoderma.
