Folia Cryptog. Estonica, Fasc. 49: 89–91 (2012)INTRODUCTIONLichenicolous fungi of the Komi Republic of Rus-sia are still scarcely known (Zhurbenko 2004, 2007; Zhurbenko et al. 2012). Herewith we report from its territory 23 species of the fungi, 10 of which are new to the republic.MATERIAL AND METHODSThe specimens were collected from different localities of the Komi Republic of Russia dur-ing the period 1994–2010, and are deposited in herbaria LE-Fungi or UPS. The specimens were examined using Zeiss microscopes Stemi 2000-CS and Axio Imager A1 equipped with Nomarski differential interference contrast optics. Microscopical examination was done in water, 10 % KOH (K), Lugol’s iodine directly (I) or after a KOH pre-treatment (K/I) or lactic acid. The length, breadth and length/breadth ratio (l/b) of ascospores are given as: (min–){X-SD}–{X +SD}(–max), where min and max are the extreme values, X  the arithmetic mean, and SD the corresponding standard deviation.THE SPECIESSpecies new to the republic are denoted by an asterisk (*).

Arnold – Pechoro-Ilychskii Reserve, upper reaches of the Ilych River, 63°03'19"N, 58°37'11"E, alt. 200 m, on thallus of Parmelia sulcata, 09.07.2009, T. P. (LE 260623).ArthoniA sp. – Luza River basin, Eshtomel Creek, 60°40'69"N, 48°36'44"E, alt. 140 m, on thallus of Lecanora hypopta, 17.09.1998, J. H. 9093 (LE 260693). – Epihymenium and hymenium dark to medium blue-green, in K becoming pale green-ish grey. Hypothecium dark purplish chestnut. Ascospores oblanceolate to narrowly obovoid, with rounded ends, (1–)3-septate, not or slightly constricted at the septa, (10–)12.5–15.5(–16.5) × (3.5–)4–5.5(–6) µm, l/b = (2.3–)2.5–3.5(–4) (n = 27, in water, K or K/I). The specimen resembles Arthonia subfuscicola growing on epiphytic Lecanora species, but differs from the latter in the pigmentation of hymenium and epihymeni-um (Almquist, 1880; Coppins & Aptroot, 2009).*briAncoppinsiA cytosporA (Vouaux) Diederich, Ertz, Lawrey & van den Boom – Yugyd Va National Park, 3 km W of Orlinaya recreation center, 65°25'31"N, 60°36'54"E, alt. 420 m, on thallus of Parmeliopsis hyperopta, 22.07.2010, J.

H. 18052, 18054 (UPS). – According to Hafellner & Obermayer (2007) the fungus is confined to Ophioparma ventosa. However, it has also been frequently reported from Rhizocarpon species.pronectriA erythrinellA (Nyl.) Lowen – Ezholty Lake, 17 km SE of Aikino village, 62°05'N, 50°09'E, on thallus of Peltigera didactyla, 21.07.2009, J.

H. 16837b (LE 260643). – Ascomata brownish/reddish orange throughout, translucent, pyriform to subglobose, immersed, showing only the ostiole, 75–125 µm diam.; wall orange, not changing colour in K and lactic acid. Asci 45–58 × 7–8 (n = 8, in water), 8-spored. Ascospores hyaline, broadly ellipsoid, ends typically rounded, 1-sep-tate, constricted at the septum, often markedly so, cells equal or not, (5.5–)6–7.5(–8) × (3.5–)4–4.5(–5) µm, l/b = (1.3–)1.5–1.7(–1.9) (n = 41, in water) [abortive non-septate subglobose spores 3.5–5 µm diam. were also seen in the asci], usually with one large guttule in each cell, wall smooth, diagonally uniseriate in an ascus. The species is similar to Pronectria fissuriprodiens Etayo, known on Lobaria pulmonaria, and P. subimperspicua (Speg.) Lowen, known on Par-melia, Physcia and Punctelia (type host) species (Etayo & Diederich, 1996; Rossman et al., 1999; Brackel, 2007). However, the former species dif-fers in having a K+ red ascomatal wall and longer 91asci, and the latter in its wider ascomata, the peridium changing colour in K and lactic acid, and slightly wider and verruculose ascospores.*protothelenellA croceAe (Bagl. & Carestia) Hafellner & H.
