Melaspilea galligena sp. nov. growing on Pertusaria cf. cribellata is described from Russian Far East. A possibly new lichenicolous Toninia species (on Parmelina tiliacea) and a species of Arthonia (on Cladonia) with 1–2-septate ascospores resembling poorly known A. lepidophila are described, illustrated and discussed. Dactylospora suburceolata is reported new to Russia and Asia, growing on a new host species Mycobilimbia carneoalbida. Tremella cetrariicola is new to Siberia and Clypeococcum cetrariae is newly documented on Vulpicida.

Asci with 4 mature, but sometimes with 5–6 germinat- ing spores. Ascospores medium olive brown to dark brown, verruculose (clearly seen in mod- erately pigmented spores), halo not observed, (12.2–)13.4–15.0(–16.2) × (5.5–)5.8–7.0(–8.5) µm, l/b = (1.6–)2.0–2.4(–2.6) (n = 64, in water). In the species protologue (Hafellner, 1994) its ascomata were described being ca. 80–120 µm diam. and ascospores somewhat narrower (13– 17 × 4.5–6 µm) and with thin halo when young. The species was formerly known in Russia from a single finding in arctic Yakutiya (Zhurbenko, 2002a). Previously reported only from Cetraria and Flavocetraria species, Vulpicida being a new host genus. CORTICIFRAGA FUCKELII (Rehm) D. Hawksw. & R.
