The lichen collection from Angola and Mozambique in COI (Coimbra, Portugal)

The importance of the COI lichen herbarium is increased by the results shown here. Fortyseven taxa are reported from Africa, forty-three from Angola and seven from Mozambique. Four species are new to Africa, 30 to Angola and 3 to Mozambique. Two species are described as new to science: Parmotrema carballalianum and Sclerococcum parmotrematis, a lichenicolous fungus living on the former. A key to all known lichenicolous species of Sclerococcum growing on Parmelia s.l. is provided.
