Life habit: lichenized Thallus: crustose, composed of small corticate granules (goniocysts) often developing below cuticle of bryophytes or below the cortex of lichens, or as a thin web of hyaline hyphae on the surface of leaves photobiont: primary one a chlorococcoid alga (Leptosira), secondary photobiont absent Ascomata: apothecial, sessile or stipitate, rounded or irregular; margin: lacking disc: pale gray to pale brown hymenium: hyaline, lacking gelatin; paraphyses: branched or not, septate, sometimes characteristically entwining the asci; hypothecium: lacking asci: clavate, thick-walled, apex thickened, I+ blue, except for an apical pore, 8-200-spored ascospores: hyaline, ellipsoid, oblong or acicular; 0-11 septate, with smooth or warted cell-wall Conidiomata: unknown Secondary metabolites: none detected Geography: Europe, North and South America and New Guinea Substrate: on soil, bryophytes or other lichens or folicolous. Notes: The distribution of the different Vezdaea species in North America is poorly known, as they have rarely been collected. Three species are known from the continent so far, except for V. rheocarpa Poelt & Döbbeler (Westberg 2004), also V. leprosa (P. James) Vězda and V. stipitata Poelt & Döbbeler
