The following three species of parastiticascomycetes are described, illustrated and discussed in detail:Octosporella ptilidii spec. nova (Pezizales) onPtilidium ciliare from Switzerland,Nectria mnii spec. nova (Hypocreales) onPlagiomnium medium from Switzerland, andPhilobryon anuliferum gen. et spec. nov. (Dothideales) onPleurozia gigantea from New Guinea. The species are known only from the type collections. It is shown that the hyphae present an array of important characters which deserve the same attention as the fruiting bodies.

No less than 3 different parasitical lichens were found on the corticolous lichenCaloplaca polycarpoides in Afghanistan. Partly, they also grow on closely allied species of the sect.Xanthoriella. Lecania triseptata begins and ends as a typical parasite, and does not form a thallus outside of its host.L. diplococca andRinodina afghanica, both described as new species, have a similar appearance; they are parasitic in the beginning, but form their own thalli outside the host later on. The 3 species are members of the small group of parasitical lichens growing on corticolous hosts. Possibly, the slow degeneration of cortices under the arid climatical conditions, has allowed the evolution of parasitic lichens of this rare type in Central Asia.
