Popis: | The status of four umbilicate lichens with lecanorine apothecia and hyaline, 1-celled ascospores is reviewed. It is concluded that Omphalodium should be emended to exclude O. arizonicum and consequently a new genus Omphalora T. Nash & Hafellner is proposed. Differences in anatomy, morphology, pseudocyphellae type, pigmentation and cell wall chemistry, and ascal dehiscence provide the primary justification for the new genus. |
