J. Hafellner, STUDIES LICHENICOLOUS FUNGI AND LICHENES - X - ARTHOPHACOPSIS, A NEW LICHENICOLOUS ASCOMYCETES GENUS (ARTHONIALES), Cryptogamie. Bryologie, lichenologie, 19(2-3), 1998, pp. 155-168
The monotypic genus Arthophacopsis is described to accomodate the lich
enicolous Arthophacopsis parmeliarum growing exclusively on species of
Parmelia s, str The new genus is founded on the very peculiar charact
er combination discocarp ascomata, fissitunicate asci and non-septate
ascospores and it is placed in the Arthoniales. Celidium tabescens Anz
i is reduced to the synonymy of Nesolechia oxyspora. A key to fungi gr
owing on Parmelia s. str is given.
