| Summary: | In summer 1997 MZ studied lichens and lichenicolous fungi in Pechora-Ilych State Reserve of Russia (Zhurbenko 2004, Hermansson et al. 2006). The area is located within the taiga zone in the headwaters of Pechora and Ilych rivers, at the eastern boundary of Europe. In the mountainous part of the reserve (Northern Ural), MZ found a rich collection of a Stigmidium Trevis. growing on Cladonia macrophylla that is here described as new to science. Material and methods The material was examined by standard microscopic techniques using microscopes MBS-1 and Mikromed-2. Photographs were taken by a Nikon Coolpix 5000 camera. The material was mounted in water, 10 % KOH (K), 1 % solution of Brilliant Cresyl blue (BCr) or Congo red (CR). The amyloid reactions were tested in 1 % Lugol’s iodine solution, directly (I) and after a KOH pre-treatment (K/I). The estimated values of the size of asci and ascospores and length/breadth ratio (l/b) of the ascospores have been given as: (min.–){X– SD}–X–{X+SD}(–max.), where min. and max. are the extreme values, X the arithmetic mean, and SD the corresponding standard deviation. Measurements of asci were rounded to the nearest 1 μm, those of the ascospores to the nearest 0.5 μm. The holotype is deposited in the mycological herbarium of the V. L. |
