Phytophthora oleae sp. nov. causing fruit rot of olive in southern Italy

“…However, it was shown that this DNA region alone may in some cases not be sufficient to differentiate closely related species characterized by identical or very similar ITS sequences (Schena & Cooke, 2006). In this context, the combination of ITS with the mitochondrial cox1 enables a precise and reliable identification (Robideau et al, 2011;Ginetti et al, 2014;Crous et al, 2017).…”

A new species of Rhodocybe sect. Rufobrunnea (Entolomataceae, Agaricales) from Italy

“…From a traditional morphological perspective, this often makes species identification difficult or even daunting. Despite this, the species in this section are quite distinct if analysed in light of ribosomal sequences (Crous et al 2017, Sesli and Vizzini 2017). …”

“…Rhodocybe matesina from Italy differs in a collybioid and slender habit (stipe up to 9 mm broad), thin context, a strongly hygrophanous pileus without reddish tinges, a smell similar to Hygrophorus penarioides Jacobsson & E. Larss., bitter and astringent taste, absence of rhizomorphs and an olive-green reaction on the pileus surface with KOH; microscopically R. matesina is distinguished due to shorter cheilocystidia (16.5–23 × 3–6.5 μm), the absence of caulocystidia and the presence in the pileipellis of rare pseudoclamps (Crous et al 2017). Rhodocybe asanii from Turkey has a collybioid habit with a 20–45 mm broad pileus, thin and very fragile context (up to 4 mm thick at pileus centre), quite distant sinuate lamellae (L = 40–50), a stipe without rhizomorphs, indistinct odour and taste, smaller spores (5.8 × 4.1 μm on average, apiculus included), no cheilocystidia and caulocystidia and growth between debris and grass in coniferous woods ( Pinus L., Picea A.…”

“…Based on the Blastn results, sequences were selected according to the outcomes of recent phylogenetic studies incorporating Rhodocybe s.l. taxa (Kluting et al 2014, Crous et al 2017, Sesli and Vizzini 2017). The nrITS and nrLSU datasets were analysed separately.…”

“…The GTR + G model was chosen for both the nrITS and nrLSU alignments. Two Lyophyllaceae, Rugosomyces (Calocybe) carneus (AF357028 and AF223178) and Lyophyllum leucophaeatum (AF357032 and AF223202) were used as outgroup taxa in both the nrITS and nrLSU analyses following Crous et al (2017) and Sesli and Vizzini (2017). The nrITS dataset was partitioned into ITS1, 5.8S and ITS2 subsets.…”
