Suillus sibiricus Singer, Farlowia 1945
No full textSuillus sibiricus (Singer) Singer, Farlowia 2 (2): 260 (1945) (Fig. 3 e, f) Pileus 30–100 mm in diam., rounded convex, convex to expended, sometimes umbonate, viscid, light-yellow, brownyellow, with separate clear reddish-brown fibrous scales or spots, margin often appendiculate with soft white-yellow patches of veil tissue. Hymenophore as tubes, adnate or slightly decurrent, yellow, turning brown-yellow. Pores are angular, stretched in radial dimension, 1–2 mm in diam.. The young specimens with fibrous, white-yellowish partial veil, leaving more or less visible ring on the stipe. Stipe 50–110 × 5–15 mm, cylindrical, pale-yellow, covered by lightbrown, yellow-brown glandular dots, which turn brown-red when damaged or touched. Basidia 20–30 × 6–8 μm, narrow-clavate, 4-spores. Basidiospores (8.5)9–11(13) × 4–5 μm, Q = 2.1–2.5, fusiform, yellowish. Cystidia (cheilo-, pleuro- and caulocystidia) 35–73 × 6–9 μm, clavate or fusiform, hyaline or with brown or dark-brown content, fasciculate, surrounded with brown amorphous pigment at the base. Pileipellis consisting of intertwined gelatinous hyphae of 3–8 μm in diameter. Ecology and distribution. The species is widespread and form ectomycorrhizae with pines: in Europe (Alps, Tatras)—with Pinus cembra, P. peuce Griseb. (1846: 349) and P. strobus; in China —with P. armandii Franch. (1884: 285) and P. koraiensis; in North America—with P. monticola Douglas ex D. Don in Lambert (1832: 144) and P. flexilis (Munoz 2005; Wu et al. 2000). In Russia, Suillus sibiricus is wide spread in Siberia and Far East, rarely found in Northern Urals in forests with Pinus sibirica (Nezdojminogo 1969; Vassiljeva 1973; Petrov 1991; Perova & Gorbunova 2001; Perevedentseva 2008; Sazanova 2009; Gorbunova & Stepantsova 2015; Filippova & Bulyonkova 2017; Degteva 2019).

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Suillus placidus Singer, Farlowia 1945
No full textSuillus placidus (Bonord.) Singer, Farlowia 2 (1): 42 (1945) (Figs. 3 c, d) Pileus 30–100 mm in diam., rounded-convex to plane, viscid to slimy, white, pale-yellow, grey-white, sometimes irregularly colored in brown tints, brown in the center, white on the edges or with brown or grayish stripes or spots. The cuticle is easily removed to the center. Tubes and pores pale-yellow, yellow, from lemon yellow to yellow-brown, adnate or slightly decurrent. Stipe 40–120 mm length, 10–23 mm width, white, yellow in upper part, all covered with small dark-brown glandular dots. Flesh white, slightly yellowish. Smell tarry. Basidia 20–25 × 6–7 μm, cylindrical, clavate, 4-spores. Basidiospores 7–9 × (2.5)3–3.5 μm, Q = 2.0–2.9, fusiform, yellowish-olive. Cheilo - and pleurocystidia 34–52 × 7–12 μm, cylindrical or slightly swollen at the ends, hyaline or with dark-brown content, fasciculate. Pileipellis ixotrichoderm, consisting of intertwined hyphae of 2–7 μm width, immersed in gelatinous substance. Caulocystidia like pleuro- and cheilocystidia, cylindrical, fusiform, clavate, with brown content, fasciculate. Clamp connections absent in all tissues. Ecology and distribution. The species has a Holarctic areal and forms ectomycorrhizae with Pinus: in Europe (Alps)—with Pinus cembra; in Siberia and Far East—with P. sibirica, P. koraiensis, P. pumila; in India —with P. wallichiana A. B. Jacks (1938: 85); in China —with P. massoniana Lamb. (1803: 12); in North America—with P. strobus (Smith & Thiers 1964; Munoz 2005; Verma & Reddy 2016). In Russia, the species was found in Far East (Vasilyeva 1973), Siberia (Perova & Gorbunova 2001; Zvyagina & Baykalova 2012) and the Urals (Perevedentseva 2008; Palamarchuk 2012; Degteva 2019). It occurs solitary or gregarious. Collection examined.

Suillus placidus can be recognized by the white or white-brown pileus, absent ring and dark-brown glandular dots on stem. In most of the identification guides, the pileus of S. placidus is white, becoming slightly yellowish over time (Smith & Thiers 1964; Munoz 2005). The glutinous layer of old basidiomata can become gray in wet weather (Smith & Thiers 1964). Some of the specimens collected by us in the study area had a white pileus, typical of this species, and the pileus of some of them was brown. Similar specimens of S. placidus with brown pileus were noted in West Siberia (Filippova 2019). Literature survey showed that the specimens from Korea were also demonstrated the color of pileus, varying from white to brown (Min et al. 2014). Molecular analysis also revealed the highest similarity of our specimens of S. placidus with those from Asia. Specimens of Suillus placidus with brown pileus are similar to S. subalpinus, but the latter is recorded only in mountains of North America.Published as part of Palamarchuk, Marina A., Kirillov, Dmitry V. & Shadrin, Dmitry M., 2021, Morphology and molecular data of the species of Suillus (Suillaceae, Boletales) associated with Pinus sibirica at the European northeast of Russia, pp. 18-34 in Phytotaxa 490 (1) on pages 28-29, DOI: 10.11646/phytotaxa.490.1.2, http://zenodo.org/record/575671
