“…3A). It has also been reported from a site in western Mongolia, just west of the mapping area, by Hauck et al (2013). This saxicolous species is well characterized by its relatively small ascospores with type B development (but the development type is often difficult to find) and septal swelling in KOH, therefore belonging to the Dirinaria-type (Sheard 2010).…”

“…This species is broadly distributed across Scandinavia and Siberia and is scattered in montane localities in the Southern Alps, Asia Minor and western North America (Mayrhofer & Sheard 2007). It has been widely reported from the Russian Far East (Chabanenko 2002) and from western Mongolia by Hauck et al (2013).…”

Rinodinais a widespread, polyphyletic genus of crustosePhysciaceaewithc. 300 species worldwide. A major missing link in understanding its global biogeography has been eastern Asia where the genus has never been systematically revised. Here we review specimen and literature records forRinodinafor north-eastern Asia (Russian Far East, Japan and the Korean Peninsula) and recognize 43 species. We describe two species,R. hypobadiaandR. orientalis, as new to science.Rinodina hypobadiais distinguished by its pigmented hypothecium,Dirinaria-type ascospores and pannarin in both thallus and epihymenium.Rinodina orientalisis characterized by its erumpent apothecia that remain broadly attached, with discs sometimes becoming convex and excluding the thalline margins, ascospores belonging to thePhyscia-type and secondary metabolites absent. Nine other species are reported from the region for the first time. These includeR. dolichospora,R. freyi,R. metaboliza,R. sicula,R. subminutaandR. willeyi. Of particular biogeographical interest are three additional new records that have western North American–eastern Asian distributions: the corticolous speciesR. endospora,R. macrosporaandR. megistospora. Six species have the better known eastern North American–eastern Asian distributions:R. ascociscana(syn.R. akagiensis,R. melancholica),R. buckii,R. chrysidiata,R. subminuta,R. tenuis(syn.R. adirondackii) andR. willeyi, and two have eastern North American–eastern Asian–European distributions:R. excrescensandR. moziana(syn.R. destituta,R. vezdae). Our study begins to close one of the largest gaps in our knowledge of circumboreal species distributions inRinodinaand, together with previous studies in North America and Europe, provides new insights into circumboreal crustose lichen biogeography.Rinodina cinereovirens(syn.R. turfaceavar. cinereovirens) is also reported as new to North America.

Lithocalla (Ascomycota, Lecanorales), a new genus of leprose lichens containing usnic acid

The identity of Lecanora ecorticata has been uncertain due to conflicting reports of the presence of zeorin and the loss of the holotype. Phylogenetic analysis suggests that the species probably belongs in Ramalinaceae, where it is the first leprose species reported. Zeorin was found to be absent in recently collected material of L. ecorticata, including specimens from the type locality, and the report of zeorin in the lost holotype is considered to be due to contamination. A new genus, Lithocalla, is erected to accommodate L. ecorticata and a second closely related species, that occurs in the Falkland Islands, is newly combined as Lithocalla malouina. A lectotype is selected for L. ecorticata. Lithocalla is characterized by a leprose thallus containing usnic acid with fatty acids and terpenoids, but no zeorin; ascomata and conidiomata are unknown.
