Humidicutis roseorubra Reschke & C. W. Fisch. 2021, sp. nov.
No full textHumidicutis roseorubra Reschke & C.W. Fisch., sp. nov. Figs. 4–6 Mykobank MB838254 Diagnosis: —Differs from other species of Humidicutis by the combination of conical, rose red basidiocarps, basidia with long sterigmata and ellipsoid to ovoid basidiospores. Etymology: —rosa (Latin) = rose, ruber (Latin) = red, referring to the colour of the basidiocarps. Type: — PANAMA. Chiriquí Province: near Cerro Punta, Entre Ríos, Montaña Azul, montane forest dominated by Quercus spp., 2300 m a.s.l., N 08°53’42.8’’ W 82°34’58.7’’, 21 June 2017, J. Rodríguez KaiR621 (holotype UCH9223, isotype M-0312081)! Basidiocarps mycenoid. Pileus 2.2–4.8 cm diam., conical to convex with acute umbo or pronounced papilla, margin straight and uneven, red (10 B 7, 11 A 6–7, 11 B 7–8), rose (11 A 5) to greyish rose (12 B 5–6), pileal surface glabrous, but innately fibrillose and with fine, protruding fibrils if seen through a lens, translucently striate up to 1/3 of the radius, hygrophanous reaction not recorded. Lamellae adnate to emarginate, often with inconspicuous decurrent tooth, ventricose, medium spaced, white, with rather even and concolourous edge. Stipe 6.5–12.0 × 0.3–0.4 cm, cylindrical, flexuous, cartilagineous, hollow, rose (11 A 3, 12 A 3–4) at the tip, pinkish white (11 A 2), pale red (9 A 3, 10 A 3), pastel red (7 A 5, 8 A 4–5), orange red (8 A 6), reddish orange (7 A 5) to light orange (6 A 5) towards the base, glabrous, polished. Basal mycelium white, rather inconspicuous to distinctly tomentose, with numerous short rhizomorphs. Odour indistinct, taste not tested. Basidiospores 6.5–7.5–8.5 × 4.5–5.0–5.5 µm, Q = 1.35–1.52–1.70 (n = 81 of 2 specimens), ellipsoid, ovoid to somewhat subcylindrical, sometimes slightly constricted, smooth, hyaline, thin-walled, inamyloid. Basidia (33–)36–45 × 5.0–7.5 µm, clavate, hyaline, thin-walled, 4-spored, with a toruloid clamp connection at the base, sterigmata mostly up to 11.0 µm long, rarely up to 17.5 µm. Hymenial cystidia absent. Lamellar trama subregular, formed by inflated to fusiform cells, (23–)30–150 × 10.0–25 µm. Pileipellis a slightly gelatinized cutis composed of somewhat interwoven hyphae, consisting of cylindrical cells, 35–100 × 2.5–9.5 µm. Subpellis not developed. Pileitrama composed of wide inflated to fusiform cells, 25–95 × (6.5–)10.0–30(–34) µm. Stipe surface composed of narrow, cylindrical cells, 100– 260 × 3.0–4.0 µm. Pigment not located. Clamp connections present in the hymenium, absent elsewhere. Habitat: — Basidiocarps found solitary or scattered in a small group on soil in a Quercus -dominated montane forest at about 2300 m a.s.l. in Chiriquí, Panama. Notes: — Humidicutis roseorubra is relatively close to H. brunneovinacea R. Garibay-Orijel in Yuan et al. (2020: s.p.), with a p-distance of 6% in the ITS. This species differs from H. roseorubra by darker pilei with brownish tones, somewhat broader ellipsoid basidiospores, and rare presence of clamp connections at the base of basidia. Humidicutis dictiocephala A. Barili et al. in Crous et al. (2017: 333), described from Ecuador, lacks pinkish tones in the pileus and has pale orange lamellae. Further, probably similar species exist (Cantrell et al. 2001; Lodge et al. 2013), however, they have not yet been described. Additional specimen examined:— PANAMA.

Art in the Age of Likeability: Nietzschean Perspectives
No full textContemporary performative art seems opposed to Nietzsche’s spiritual aristocracy because it promotes a democratisation and anarchisation of art through the involvement of the public as performer, as well as the creators’ identification with their artwork. Social media have gone a step further, by linking performances to an even stricter submission to the verdict of the public. However, art in the age of likeability also preserves distinctive Nietzschean features. In the end, whether a form of creativity is prone to nihilism or life-affirming rests entirely on the spiritual health or sickness of the creator

Psychological Issues in Education and Health. Proceedings of 1st Scientific Meeting University of Evora and University of Leipzig
No full textMental Health, Stress, Learning, Emotional Intelligence & Resilience are important topics of current clinical and pedagogical Research in many universities of the world.
In the frame of the collaboration agreement between the University of Evora (Portugal) and the University of Leipzig (Germany) in the field of Psychology, a group of Psychologists of both institutions and guests from the United States and Indonesia met in Evora on 13th May, 2016, in order to explain each other their current research interests and present results in the above mentioned topics of research. The goal was to exchange points of views on Psychology, science and society.
During this scientific meeting, several papers on the application of Psychology in the fields of education, public health, clinical disorders, child development and social issues were discussed. Thirteen of them have been selected to be part of the present volume, which contains the results of those fruitful discussions.
The main issues that are matter of concern in modern societies are here represented, like
• drug consumption,
• healthy habits of living,
• learning at school and at the university,
• depression,
• teachers health
• health in the retirement phase of life,
• personal resilience,
• stress in different populations and groups &
• citizenship and media.
All participants were aware of the existence of common mental health and education problems at an international level and of the important role of Psychology to make a contribution for the solution of those problems in the present world.
The aim of this volume is to give a glance on current developments of research on such topics in different countries (Portugal, USA, Indonesia, Sri Lanka & Germany).Universidade de Évora & Universidade de Leipzi

Chiriquí Province: Sendero Los Quetzales, between Cerro Punta and Bajo Boquete, N 08°50’47.7’’ W 82°32’07.8’’, 2350 m a.s.l., upper montane cloud forest, on soil, 01 July 2018, <i>K. Reschke, T. Hofmann</i> (<i>KaiR699</i>) (holotype UCH9257, isotype M-0312083)!</p> <p> <b>Description:</b> —Thallus terricolous, covering an area of about 1.5 m ², thin, but visible as a green layer. Basidiocarps clavarioid, 5.0−7.0 mm high, emerging from the thallus, gregarious, scattered, predominantly separate, rarely two basidiocarps combined, entire, incised to fringed at the apex, or forked with 2–3 branches starting from half of the height, solid, delicate but waxy-tough to cartilaginous. Fertile part 2.0−5.5 × 0.3−0.5 mm, dorsiventrally applanate with a concave outline, with a tendency to furl along the length-axis when dry, with acute, straight or hooked, rarely obtuse apices, white to orange white (5A1−2). Stipe 0.5−1.5 × 0.3−0.7 mm, cylindrical to somewhat flattened, smooth, whitish. Dorsal side of the fertile part sterile, hymenium on ventral side of the fertile part and partly on apices, sometimes on both sides of the apex.</p> <p>Basidiospores 6.0−7.3−8.5 × 2.0−3.7−3.5 µm, Q = 2.10−2.79−3.35 (n = 50), oblong to slightly allantoid, often somewhat centrally constricted, hyaline, smooth, thin-walled, inamyloid, with oil drop, frequently forming aggregates of 4−8 spores. Basidia 25−35 × 5.0−7.0 µm, initially ovoid to clavate, suburniform at maturity, thin-walled, hyaline, 4−8-spored, with up to 6.0 µm long sterigmata, clamped, easily collapsing after spore-shedding. Hyphal system monomitic. Hyphae generally thin-walled, septate, with clamp connections. Subhymenium composed of densely arranged, branched and intertwining hyphae. Trama hyphae parallel, sparsely branched, tightly packed and rarely intertwining, composed of cylindrical cells, approx. 50 × 1.0−2.0 µm. Some hyphae with refractive content present. Thallus consisting of a network of fungal hyphae, wrapping green algae, thus forming bulbils with a close contact of myco- and photobiont. Algal cells 8.0–9.0 × 6.0−7.0 µm, broadly ellipsoid, each surrounded by fungal hyphae of 1.0−2.0 µm diameter. Algae frequently forming ellipsoid autospores, 4.0−6.0 × 3.0−5.0 µm. Hyphae between bulbils narrow, about 1.0 µm wide.</p> <p> <b>Habitat:</b> — Terricolous on loamy, stony soil, on a moist steep enbankment along a mountain path in montane cloud forest at 2350 m a.s.l. on the north slopes of Volcán Barú in Chiriquí, Panama.</p> <p> <b>Notes:</b> —In the phylogeny (Fig. 8), <i>Multiclavula caput-serpentis</i> forms a clade with <i>M. ichthyiformis</i> Nelsen <i>et al.</i> in Nelsen <i>et al.</i> (2007: 1290), which also has dorsiventral basidiocarps. <i>Multiclavula ichthyiformis</i>, however, differs from <i>M. caput-serpentis</i> by basidiocarps with a strigose stipe and a thin, translucent fertile part, as well as by globose basidiospores and a p-distance of 12% in the ITS sequence data. <i>Multiclavula hastula</i> (Corner 1950: 370) Petersen (1967: 214), described from Malaysia, is similar to <i>M. caput-serpentis</i> by small, pale flesh coloured basidiocarps of similar shape. It was, however, described and illustrated by Corner (1950) as associated with cyanobacteria and having thin, soft flesh, hyphae with ampulliform swellings, and 4- to 6-spored basidia. The basidiospores of <i>M. hastula</i> are ellipsoid to narrowly ovoid and 5.0–7.0 × 2.0–3.0 µm in size (Petersen 1967), while those of <i>M. caput-serpentis</i> are oblong to slightly allantoid and longer, 6.0−8.5 × 2.0−3.5 µm. The holotype of <i>M. hastula</i> has been studied by Corner (1950) and Petersen (1967), it is stored in formaline and thus not suitable for molecular analysis. Further collections of <i>M. hastula</i> have not been reported, but are necessary to reveal its phylogenetic affinities. <i>Multiclavula petricola</i> Masumoto & Degawa (2020: 157), described from Japan, differs from <i>M. caput-serpentis</i> by its occurrence on stone, somewhat longer basidiospores and a more pronounced globular thallus. A dorsiventral organisation of its basidiocarps was not reported (Masumoto & Degawa 2020). A further specimen of <i>Multiclavula</i> (PAN625), with affinity to <i>M. mucida</i> (Persoon 1797: 55: Fr.) R.H. Petersen (Fig. 8), was collected in Panama. However, the material of this putatively further new species is insufficient for description.</p>Published as part of <i>Reschke, Kai, Lotz-Winter, Hermine, Fischer, Christian W., Hofmann, Tina A. & Piepenbring, Meike, 2021, New and interesting species of Agaricomycetes from Panama, pp. 1-26 in Phytotaxa 529 (1)</i> on pages 8-10, DOI: 10.11646/phytotaxa.529.1.1, <a href="http://zenodo.org/record/5814166">http://zenodo.org/record/5814166</a>
