Taxonomic status and epidemiology of the mesoparasitic copepod Pennella balaenoptera in cetaceans from the western Mediterranean.

2018

Pennella balaenoptera is a mesoparasitic copepod that has been reported in at least 17 cetacean species. Subtle morphological differences in the first antennae of adult females have been used to discriminate this species from P. filosa, a species infecting fishes. Other morphological traits are unreliable because of their high plasticity, and no molecular data are available to confirm the taxonomic status of P. balaenoptera as an independent species. We found no consistent morphological differences of the first antennae between P. balaenoptera and P. filosa collected from cetaceans and fish in the western Mediterranean. Molecular data on the mitochondrial cytochrome oxidase subunit I failed…

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.

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.

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.

Strain CECT 7735T, a marine Gram-reaction negative, aerobic, non-motile bacterium, was isolated from coastal seawater in Valencia, Spain. Strain CECT 7735T is chemoorganotrophic, mesophilic, slightly halophilic, grows at 15–28 °C but not at 4 or 37 °C, requires seawater for growth and grows up to 6 % salinity. The major cellular fatty acid is summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). The G+C content of the genome is 55.7 mol%. Comparative analysis of the 16S rRNA gene sequence shows the strain is affiliated to the family Rhodobacteraceae , in the class Alphaproteobacteria , with highest similarities to Phaeobacter species (97.0–97.5 %), Shimia species (96.5–97.3 %) and Pseudopelagico…

Mangleticornia (Amaranthaceae: Salicornioideae) — a new sister for Salicornia from the Pacific coast of South America

2017

Mangleticornia ecuadorensis is a newly recognized monotypic genus from SW Ecuador and adjacent N Peru, where it had previously been identified as Salicornia fruticosa (Arthrocnemum fruticosum) or S. peruviana. It occurs on the coast adjacent to or in Equatorial-Pacific mangroves. Molecular phylogenetic evidence determines that this genus is distinct from and sister to Salicornia sensu lato, and is supported by morphological evidence. The genus is distinguished by a unique combination of characters that are otherwise rare in Salicornioideae: flowers without a visible perianth, anthers and stigmas exserted through pores in the fleshy cortical tissue of the segments, fruit included in the segm…
