Acarospora nitrophila H.Magn.

Acarospora nitrophila is one of the most poorly known Acarosporaceae in Europe. The problem was caused by Magnusson’s own confusion of the differences between A. nitrophila and especially A. praeruptorum. This confusion was made worse by Clauzade et al. (1981) who reduced seven species of Acarospora to varieties and forms of A. nitrophila. The name was often slapped on many other species of Acarosporaceae that could not be determined. Many reports from the Czech Republic are A. praeruptorum. The species is considered extinct in the Czech Republic. The only so far known record was collected on sunny rocks near Libčice nad Vltavou by A. Hilitzer in 1926. Its center of distribution is in Fennoscandia. For a description and pictures see Knudsen & Kocourková (2017); the description mentions an IKI+ red subhymenium but it is blue though sometimes fades to IKI-.
