As a result of fundamental changes in the International Code of Nomenclature on the use of separate names for sexual and asexual stages of fungi, generic names of many groups should be reconsidered. Members of the ECMM/ISHAM working group on Pseudallescheria/Scedosporium infections herein advocate a novel nomenclature for genera and species in(More)
BACKGROUND Mushroom poisoning by some species of the Cortinarius (Agaricales) often lead to irreversible renal failure caused by the nephrotoxin orellanine. In 1994 and 1995, six poisoning outbreaks involving ten individuals in Northern Italy and in Austria were investigated. METHODS A total of 87 clinical samples (urine and blood samples including renal(More)
Mushrooms of the Cortinarius species are nephrotoxic and can cause severe acute renal failure. The toxic effect is due to orellanine. It is suspected that the cytotoxic damage is caused by the production of oxygen-free radicals. Renal pathology shows tubular necrosis with interstitial nephritis. In addition to accidental intoxications as a consequence of(More)
Benzoxazolinone detoxification is similar in plants grown under sulfur deficiency conditions and in control plants grown with an optimal S supply. However, when S-deficient plants were treated with metolachlor before benzoxazolin-2(3H)-one (BOA) incubation, detoxification was reduced, as indicated by a lower accumulation of the detoxification products(More)
Phytomyxids (plasmodiophorids and phagomyxids) are cosmopolitan, obligate biotrophic protist parasites of plants, diatoms, oomycetes and brown algae. Plasmodiophorids are best known as pathogens or vectors for viruses of arable crops (e.g. clubroot in brassicas, powdery potato scab, and rhizomania in sugar beet). Some phytomyxid parasites are of(More)
BACKGROUND Renal failure as a consequence of eating mushrooms has been reported repeatedly after ingestion of webcaps of the Cortinarius orellanus group. But mushrooms of the genus Amanita can also cause renal failure: Amanita smithiana (North America) and Amanita proxima (Mediterranean area). Here, we discuss poisonings caused by other white amanitas. A(More)
CONTEXT Here we present a case of Amanita smithiana poisoning resulting in acute kidney injury requiring dialysis, and highlight laboratory methods used to confirm the diagnosis. Identification of Amanita smithiana toxin using thin-layer chromatography can provide greater diagnostic certainty than history and renal function tests alone. CASE DETAILS A(More)
The genus Roesleria was introduced with the single species Roesleria hypogaea (current name: R. subterranea) by Thümen in 1877. The species was originally described from roots of grapevine and recognised as a facultative root-rotting parasite. The mazaediate ascoma with evanescent asci led to the assumption that Roesleria would be an ally of mazaediate(More)
Sirs, With interest we read the “Clinical Quiz” recently published in Pediatric Nephrology in which Talmud et al. [1] reported on severe mushroom poisoning caused by Cortinarius orellanoides. They confirmed their clinical findings by observations of basidiospores in the leftovers of the contaminated meals. Unfortunately, the report contains a number of(More)
