New species and records of saxicolous lichens from the Kodar Range (Trans-Baikal Territory, Russia)

Abstract

Fifty-six species of saxicolous lichens are reported for the first time from the Kodar Range. Circinaria scyphulifera is described as new to science. Aspicilia nikrapensis and Fuscidea submollis are new for Russia; Aspicilia sublapponica, Lepra monogona and Thelignya lignyota are new for southern Siberia; and 35 species of saxicolous lichens are reported for the first time for the Stanovoye Nagor’e highlands. Fuscopannaria ahlneri alredy appears in the Red Data Book of the Trans-Baikal Territory.

New records of lichens from the Russian Far East. I. Fuscidea submollis and other arctic-alpine species

“…In addition, both species differ by distribution: while F. mollis has wide Holarctic area (has been recorded from Europe, Asia, North America and Arctic), Fuscidea submollis until recently has been considered as an endemic species for Japan (Shimizu, 2004;Ohmura, Kashiwadani, 2018). It is reported now from two localities in Asian Russia: South Siberia (Kodar range) (Chesnokov et al, 2018) and South Far East (Sikhote Alin Range). There are only few saxicolous species with a similarly confined Far East Asian-East Siberian distribution area, e.g.…”

“…The diagnostic characters of the genus are crustose thallus with a brownish hypothallus, lecideoid apothecia with black to brown-black discs, a proper margin that is paler than the discs, brown epyhymenium and excipulum, green coccoid alga, slightly tapered or cylindrical-clavate asci of the Fuscidea-type and ellipsoid to globose, oblong or bean-shaped, simple to one-septated ascospores, which are colorless and becoming brownish with the age (Fryday, 2008). Eighteen species of Fuscidea were reported for Russia (Urbanavichus, 2010;Stepanchikova et al, 2017;Chesnokov et al, 2018).…”

“…During the preparation of this paper the first record of Fuscidea submollis Mas. Inoue in Russia from Kodar (South Siberia) was published (Chesnokov et al, 2018), but the data were insufficient and contained only the information on the label and the TLC results. Here we report the second record of the species in Russia and its first record from the Russian Far East integrated with the detailed information on the species and a comparison with closely related taxa.…”

New records to the lichen biota of Russia, 1 – Sakhalin Region, with new records for the Russian Far East and the Asian part of Russia

“…This record is the third in Russia. Previously, the species was discovered in SIB: Bai (Chesnokov et al 2018) and RFE: Pri (Yakov chenko et al 2019). It is reported for the first time for Sakhalin.…”

Circinaria nimisii (Megasporaceae, lichenized Ascomycota), a new manna lichen from Greece

“…The genus Circinaria Link (Ascomycota, Lecanoromycetes, Pertusariales, Megasporaceae) was resurrected by Nordin et al (2010) and comprises c. 40 species worldwide. The genus is characterized by crustose (Chesnokov et al 2018), umbilicate, fruticose, subfruticose, or spherical growth forms, a thickened medullary layer, usually with pseudocyphellae, 2-6 spores per ascus, low secondary metabolite diversity, and relatively short conidia (Sohrabi et al 2013). It is distinguished from Aspicilia and the other genera within Megasporaceae by thallus morphology, presence/absence of pseudocyphellae, the number of ascospores per ascus and the size of ascospores, conidia length, and the presence/absence of some compounds such as aspicilin.…”
