Henssenia Koerberia Tingiopsidium Koerberiaceae is a small family of lichen-forming fungi in the order Peltigerales.
The family was proposed by Toby Spribille and Lucia Muggia in 2012, after molecular phylogenetic analysis revealed the existence of three lineages of lichen-forming fungi in the suborder Peltigerineae of the order Peltigerales.
The lineages represented the genera Steinera, Koerberia (the type genus of the family), and Vestergrenopsis.
[5] Members of the Koerberiaceae have thalli that are squamulose (scaley) to placodioid, and have deep grooves on the upper surface that radiate outward from the centre of the thallus.
The photobiont partner is a cyanobacteria, either from genus Nostoc or from the family Scytonemataceae; they are bundled together in rows under the upper cortex.
