No full textArtimpaza brevilineata Tian & Chen, 2012 in Tian, Chen & Li, 2012: 43, figs. 1–9. (Figs. 28a, b) Type locality: China, Yunnan, Pu’er City, Yutang. Gender: female. Date collected: 2011.V.25 (2010.V.25, in the original description, is incorrect). Collector: Li-Chao TIAN & Gui-Qiang HUANG. Paratypes: 1 female, China, Yunnan, Lincang City, 1980.VI.1, Fen LIU leg. Remarks: In the original description, the type locality is “ Yunnan, Jinghong” while it is “ Yunnan, Yutang” according to the label. “Yutang” is actually in Pu’er, not Jinghong. The first author described the type locality by mistake. In the original description, the collector was only listed as Li-Chao TIAN, which was a mistake.Published as part of Li, Zhu & Chen, Li, 2020, Primary types of longhorned beetles (Coleoptera, Cerambycidae, Vesperidae and Disteniidae) of Southwest University (SWU), pp. 25-46 in Zootaxa 4718 (1) on page 33, DOI: 10.11646/zootaxa.4718.1.2, http://zenodo.org/record/360220
Herpothallon polyisidiatum P. F. Chen & L. L. Zhang 2022, sp. nov.
No full textHerpothallon polyisidiatum P.F. Chen & L.L. Zhang, sp. nov. (Figure 2) Mycobank number: 839109 Type:— CHINA. Guangdong: Qingyuan City, Mangshan Forest Park. 1716 m elev., 24°55′22.85″ N, 112°59′35.67″ E, on bark of trees, 17 May 2019, L. S. Wang & X. Y. Wang 66649 (Holotype in KUN) Description:—Thallus corticolous, up to 4 cm in diam., closely appressed to the substrate, firm and sometimes flaking off, minutely felty, dull, yellowish white to light yellow, in section up to 150 µm thick, with many calcium oxalate crystals in the thallus. Hypothallus byssoid, white, composed of 1–3 µm wide hyphae. Prothallus up to 1 mm broad, byssoid, composed of interwoven and radiating hyphae, whitish. Pseudisidia numerous, cylindrical, unbranched or sparsely branched, rather compact yet felty, of the same colour as thallus, up to 0.3 × 0.1 mm. Photobiont Trentepohlia, single or a few cells aggregated, cells globose, 6–10 × 5–8 µm, yellowish green. Asci and pycnidia not seen. Chemistry and spot tests:— Thallus K+ yellow, C–, P+ orange, I–. TLC: stictic acid. Etymology:— The epithet “ polyisidiatum ” refers to abundant pseudisidia. Ecology and distribution: —The new species was found growing on bark of a tree in Mangshan Forest Park. Note:—This species can be distinguished by its compact pseudisidia and the presence of stictic acid as the only metabolite. Herpothallon sticticum Jagadeesh Ram & Sinha (2011: 314), H. isidiatum Jagadeesh Ram & Sinha (2009: 611) and H. elegans G. Thor (2009: 39) also contain stictic acid, but H. sticticum has a grey to pale yellow–grey thallus and dense, minutely felty, granular globular to short cylindrical 0.05–0.1(–0.25) × 0.05–0.1(–0.2) mm wide pseudisidia with projecting hyphae (Jagadeesh & Sinha 2011); H. isidiatum has a grey to whitish grey thallus and larger pseudisidia (0.08–0.15 × 0.5–1.5 mm) with dark brown to black pycnidia at the tips (Jagadeesh & Sinha 2009); H. elegans has a hypothallus with a red layer (partly absent) and with a smooth and black layer and dark red prothallus beneath that (Aptroot et al. 2009). This species can also be confused with Diorygma antillarum (Vain.) Nelsen, Lücking & Rivas Plata (2012: 318). In Diorygma, the hypothallus is compact, not byssoid, and pseudisidia are unknown with the exception of D. antillarum, which has a distinct carbonized hypothallus, but contains different substances from H. polyisidiatum (Nelsen et al. 2012).Published as part of Chen, Pengfei, Liu, Linlin, Xie, Congmiao & Zhang, Lulu, 2022, Four new species of Herpothallon (Arthoniaceae, Arthoniales, Arthoniomycetes, Ascomycota) from China, pp. 83-91 in Phytotaxa 536 (1) on pages 84-88, DOI: 10.11646/phytotaxa.536.1.5, http://zenodo.org/record/622456
Herpothallon viridi-isidiatum P. F. Chen & L. L. Zhang 2022, sp. nov.
No full textHerpothallon viridi-isidiatum P.F. Chen & L.L. Zhang, sp. nov. (Figure 4) Mycobank number: 839111 Type:— CHINA. Zhejiang: Lishui City, Jingning County, Baiyun Protection Station. 1298.73 m elev., 27°43′11.07″ N, 119°38′49.33″ E, on bark of Cunninghamia lanceolata (Lamb.) Hook., 2 December 2020, C. G. Zhao & L. L. Zhang 20200806 (Holotype in SDNU) Description:—Thallus corticolous, up to 3–5 cm in diam., loosely appressed to the substrate, sometimes flaking off, minutely felty, dull, pale mineral greyish-green, in section up to 150 µm thick, with many calcium oxalate crystals in the thallus. Hypothallus byssoid, dirty whitish, composed of 1–3 µm wide hyphae. Prothallus up to 1 mm wide, byssoid, composed of interwoven and radiating hyphae, dirty white in inner and whitish to pale brown in outer parts. Pseudisidia numerous, cylindrical, branched, rather compact yet felty, of the same colour as thallus or often paler in the upper part, up to 0.2 × 0.1 mm. Photobiont Trentepohlia, single or a few cells aggregated, cells globose, 7–12 × 4–8 µm, yellowish green. Asci and pycnidia not seen. Chemistry and spot tests: —Thallus and prothallus K+ yellow, C+ red, P+ pale yellow, I+ blue in medulla. TLC: gyrophoric acid, lecanoric acid, umbilicaric acid and unknown substances. Etymology:— The epithet “ viridi-isidiatum ” refers to the green colour of the pseudisidia. Ecology and distribution: —The new species was found growing on Cunninghamia lanceolata (Lamb.) Hook., at Baiyun Protection Station. Specimen examined:— CHINA. Zhejiang: Lishui City, Jingning County, Baiyun Protection Station. 1298.73 m elev., on bark of Cunninghamia lanceolata (Lamb.) Hook., 2 December 2020, C. G. Zhao & L. L. Zhang 20200810 (SDNU). Note:— This species is characterized by cylindrical pseudisidia with many hyphae on the surface and the presence of gyrophoric acid, lecanoric acid, umbilicaric acid. Although H. philippinum also has a C+ red thallus and prothallus (gyrophoric acid, ± confluentic and/or lecanoric acids), it has felty pseudisidia with projecting hairs (up to 1.0 × 0.1 mm). Herpothallon echinatum Aptroot, Lücking & Will-Wolf (2009: 38) also has a loosely appressed thallus, but contains psoromic acid and lacks calcium oxalate (Aptroot et al. 2009). Another morphologically similar species is H. isidiatum, but the species is characterized by stictic acid and smaller pseudisidia with dark brown to black pycnidia at the tips (Jagadeesh & Sinha 2009).Published as part of Chen, Pengfei, Liu, Linlin, Xie, Congmiao & Zhang, Lulu, 2022, Four new species of Herpothallon (Arthoniaceae, Arthoniales, Arthoniomycetes, Ascomycota) from China, pp. 83-91 in Phytotaxa 536 (1) on pages 89-90, DOI: 10.11646/phytotaxa.536.1.5, http://zenodo.org/record/622456

ikurecic/pds2020_lockdowns: Causes of COVID-19 lockdown policies in US states — presented on 19 June 2020
No full textAs part of the Political Data Science course held at the Technical University of Munich in 2020, Linlin Chen and I (Ivana Kurecic) looked at the causes that led to the enforcement of COVID-19 lockdown policies in US states using a panel data analysis.
The dataset we used contained a variables we could collect from publicly available sources, including the CoronaNet Research Project (policy data), Data Repository by the CSSE at Johns Hopkins University (daily COVID-19 deaths per US state), US Bureau of Labor Statistics (new weekly unemployment claims), US Bureau of Economic Analysis (GDP per capita for each US state), and the US Census Bureau (regionality of US states).
Our results, explanations, and links to data sources can be found here: https://happyturtlethings.net/causes-of-lockdown-policies-project/
We also made an interactive presentation in Flourish: https://public.flourish.studio/story/415257/
