Özet

A recent collection ofLepiota spiculatafrom the Dominican Republic is presented here. Macro- and micromorphological features ofL. spiculataare described in detail, and its evolutionary (phylogenetic) position withinLepiotasect.Ovisporae, in the subincarnata/brunneoincarnata clade, is assessed on the basis of a combined nrLSU + nrITS +rpb2+tef1analysis. Additionally, high levels of deadly amatoxins were detected and quantified inL. spiculatafor the first time by HPLC analysis; in particular, alpha-amanitin was found at concentrations up to approximately 4 mg/g dry weight, which renderL. spiculataa potentially lethal mushroom, if ingested.
