Remarks (public):The basidiocarps of the species of Exidiopsis are capable of indeterminate growth both laterally and vertically. Thus, basidiocarps of this genus vary considerably in thickness and lateral dimension.
As defined above, the genus Exidiopsis would not include several species that have been assigned by some ( Wells, 1962) to Eichleriella Bres. We now believe that Eichleriella alliciens ( Berk. ex Cke.) Burt, E. leucophaea Bres., E. deglubans ( Berk. et Br.) Reid, and E. schrenkii Burt can be segregated into a separate taxon on the basis of a basal layer of hyphae with thick, brownish walls. In some species of Exidiopsis a basal layer of hyphae is present, but it seems to represent the hyphae of the basidiocarps spreading from a point of eruption through the substrate, and the hyphae lack thickened, brownish walls. While the thicker specimens of some species of Exidiopsis, such as E. griseobrunnea, superficially resemble the species of Eichleriella, the hyphae of the basal hyphal layer of the species of Exidiopsis lack the thickened, brownish walls.

Basidiocarps resupinate and indeterminate, mucous to waxy gelatinous, arid waxy, or coriaceous, drying to an invisible film or a conspicuous crust; margins thinning out to abrupt, sometimes reflexed upon drying; in section consisting of a basal prostrate layer of thin- or thick-walled, hyaline hyphae giving rise to an ascending layer that terminates in the hymenium of basidia and dikaryophyses, cystidioles and cystidia present or absent, prostrate basal layer sometimes lacking in some species or in some portions of the basidiocarp, collapsed basidia usually present in the ascending layer, growth strata rarely present; subhymenial hyphae with clamps; dikaryophyses simple to much branched, sparse to abundant; basidia subglobose, ovate, obovate to pyriform, less often with enucleate stalks, always with basal clamps, forming ( 2- ) 4 hypobasidial segments; epibasidia usually present, usually tubular; basidiospores subglobose, elliptical to allantoid, smooth, usually capable of germinating by repetition.
