Genus of lichens
Santessoniella is a genus of lichenized fungi in the family Pannariaceae. The classification reflects various changes made based on the Systema Ascomycetum and Myconet in the Deep Hypha issue of Mycologia.
The genus was circumscribed by Aino Marjatta Henssen in Acta Univ. Upsal., Symb. Bot. Upsal. vol.32 (1) on page 76 in
1997.
The genus name of "Santessoniella" is in honour of Rolf Santesson (1916–2013), who was a Swedish lichenologist and university lecturer.
