Botryosphaeriaceae species associated with diseased loquat trees in Italy and description of Diplodia rosacearum sp. nov

2016

[EN] Loquat (Eriobotrya japonica) is a fruit tree cultivated in several countries in the Mediterranean region. A survey of a loquat orchard in Sicily ( Italy) revealed the presence of plants showing dieback symptoms and cankers with wedge-shaped necrotic sectors. Fungi from the genera Diplodia and Neofusicoccum were isolated from symptomatic plants. On the basis of morphological characters and DNA sequence data four species were identified, Neofusicoccum parvum, N. vitifusiforme, Diplodia seriata and a novel Diplodia species, which is here described as D. rosacearum sp. nov. Inoculation trials of loquat plants cv Sanfilipparo showed that N. parvum, D. seriata and D. rosacearum were pathogen…

Buchwaldoboletus lignicola (Boletaceae), a rare basidiomycete from Europe

2017

AbstractBuchwaldoboletus lignicola is a rare basidiomycete with fragmented distribution in Europe. The taxonomy, ecology and distribution of this species is reported. The new locality from central Sicily widens the area of distribution of B. lignicola in Europe.

We present a taxonomic revision ofCremastosperma, a genus of Neotropical Annonaceae occurring in lowland to premontane wet forest, mostly in areas surrounding the Andean mountain chain. We recognise 34 species, describing five as new here: from east of the Andes,C.brachypodumPirie & Chatrou,sp. nov.andC.dolichopodumPirie & Maas,sp. nov., endemic to Peru;C.confusumPirie,sp. nov., from southern Peru and adjacent Bolivia and Brazil; andC.alticolaPirie & Chatrou,sp. nov., at higher elevations in northern Peru and Ecuador; and from west of the Andes,C.osicolaPirie & Chatrou,sp. nov.endemic to Costa Rica, the most northerly distributed species of the genus. We prov…

First record of Capnobotrys dingleyae (Metacapnodiaceae) on Taxus baccata for southern Europe

2017

Field investigations carried out in a mixed forest of Fagus sylvatica and Taxus baccata in the Nebrodi Natural Park (Sicily, southern Italy) allowed us to identify a very rare lignicolous ascomycete Capnobotrys dingleyae, a new species for southern Europe.

Epiphytic communities of open habitats in the western Tian-Shan Mts (Middle Asia: Kyrgyzstan)

2016

The paper presents the results of bryosociological research conducted on the epiphytic vegetation in the western Tian-Shan Mountains in 2013. The surveys on epiphytic bryophyte and lichen communities were done on 115 sites with different quantity of trees (solitary, in alleys or wood plots along river valleys) distributed in several mountain ranges within study area. In total 21 epiphytic moss species were found during research which composes characteristic species combinations making apparent difference between associations. As a result of field research and numerical analyses, three separate groups of samples corresponding to seven associations and one community within three alliances: Ul…

Se describe el híbrido Sideritis ×pertegasii recolectado por Pau, interpretando su origen como producto del cruzamiento entre S. spinulosa subsp. subspinosa y S. tragoriganum subsp. juryi (Labiatae). Se presenta una descripción morfológica, una tabla con los principales caracteres diagnósticos del híbrido frente a sus progenitores, una fotografía del pliego con el holotipo y dos ilustraciones con iconografía del híbrido y sus progenitores.

Effect of weak magnetic fields on the in vitro propagation of Genista aetnensis (Raf. Ex Biv.) Dc.

2017

Over the years, many studies have emphasized the importance of the magnetic fields (MF), used as a safe alternative choice to improve agricultural production. The induction effect of different magnetic fields varies depending on the species, explants typology, intensity of magnetic field and period of exposure. The aim of the present study was to investigate the application of a continuous magnetic field induction, at different exposure times, as a production enhancement for in vitro culture of Genista aetnensis, an endemic shrub commonly named 'Mount Etna broom'. An in vitro protocol has been settled for the conservation of the species. Plantlets cultured onto a solified Murashige and Skoo…

Typification of the Linnaean name Ambrosinia bassii and other nomenclatural remarks in the genus Ambrosinia (Araceae)

2018

Although Ferdinando Bassi is the nomenclatural authority for the genus Ambrosina, the correct spelling of the name should be the Linnaean “Ambrosinia”. A lectotype is designated for A. bassii, the only species currently recognized. In addition, two lectotypes, two epitypes and one neotype are designated for other names of taxa currently treated within the infra-specific variability of A. bassii.
