Toninia tecta, a non-lichenized obligately lichenicolous fungus, is described new to science. The
species is known from several sites in midcontinental North America. Toninia tecta has an endokapylic
thallus with dark superficial apothecia restricted to the sheltered undersides of thalli of saxicolous umbilicate
species of Dermatocarpon. The new species is characterized by 3-septate ellipsoid ascospores, elongate
filiform conidiospores, a reddish brown hypothecium and grey to greenish epithecium that reacts KOH–,
HNO3þ violet. Features of the species are compared with those of other lichenicolous taxa in the genus.
Keywords: Lichenicolous fungi, central North American grasslands.
