Rinodina pyrina
Rinodina pyrina (Ach.) Arnold, Flora (Regensburg) 64: 196 (1881), IF: 404474
Facesoffungi number: FoF05806
Lichenized on dead stem. Thallus: crustose, greenish grey, granulose. Sexual morph: Apothecia 0.2–0.6 mm wide, arising singly or in small groups, sessile, erumpent from the substrate, cupulate, black when fresh. Hypothecium convex. Disc black. Margins green. Hymenium hyaline, enclosed in a thick gelatinous matrix. Epithecium slightly swollen paraphyses apices form pseudo epithecium above the hymenium, hyaline to brownish. Excipulum 30–50 µm outer cells are textura angularis to globulosa inner layer composed of hyaline loosely arranged hyphae. Paraphyses 2.2–2.8 µm wide at the apex, numerous, filiform, slightly swollen at the apex, aseptate, slightly branched at the base. Asci 40–45 × 10–15 µm, 8-spored, short sessile, cylindric–clavate, rounded at the apex. Ascospores 9–11 × 6–7 µm, multiseriate, ellipsoid, one septate, olive green to brownish,
guttulate, smooth, thin walled. Asexual morph: Undetermined.
Material examined – Ukraine, Donetsk region, Shakhtyorsk district, natural landscape park “Donetsk Ridge” (“Donetsky Kryazh” in Russian and Ukrainian), fragment of salty steppe (N 47.91320°, E 38.75180°), on dead stems of Pontic-Caspian endemic plant Calophaca wolgarica (L. f.) DC. (Fabaceae), 19 May 2017, Timur S. Bulgakov, DNK-071 (MFLU 18-0703).
GenBank accessions – ITS-MK499347, LSU-MK499359
Notes – Our collection of DNK-071 from Ukraine grouped with Rinodina pyrina collections from Sweden and Austria (Fig. 12). The Rinodina pyrina clade of these three strains received a high bootstrap support (93%) and the ITS data of our new collection shows 99% similarity to the ITS data of other R. pyrina collections (GZU 000272653, Mayrhofer 483). Moreover, morphological characters of our collection are in agreement with the description of Rinodina pyrina provided by Castillo et al. (2013). This species was previously recorded from Ukraine by Gromakova (2011) and Nadyeina (2007), but this is the first record of this species from the naturallandscape park “Donetsk Ridge”
