R. americana R. anombrophila R. dendritica R. leopoldii R. syncesioides R. virginea R. zwackhii Reichlingia is a genus of lichen-forming fungi in the family Arthoniaceae.

Around the edges, a faint, whitish, hair-like prothallus may be visible, although when it encounters other lichens, a darker brown boundary line often forms.

Its reproductive structures, the apothecia, vary in shape—from round and polygonal to short and slit-like (lirelliform)—and may form small, lobed clusters or irregular, star-like patterns.

[4] Just below the surface, the epithecium (the top layer of the spore-producing region) may appear greyish due to the presence of pale crystals, or it can be dark brown.

The resulting conidia (asexual spores) are also dark brown, irregularly branched, and have a warty surface, often visibly pinched at their internal divisions.
