While studying materials collected in tropical rain forests of Cát Bà National Park (Vietnam) two species of Lepiota were discovered: L. erythrosticta and L. omninoflava. Both species are reported as new for Vietnam. Lepiota erythrosticta represents the sect. Stenosporae, possesses spurred basidiospores and purple basidiomata. Lepiota omninoflava belongs to the sect. Eriophorae, has ovoid basidiospores and yellowish basidiomata. Photographs of basidiomata, illustrations and descriptions of macro- and micromorphological features, phylogenetic tree and discussion on allied species are given.
Иванова Д.Д., Агеев Д.В., Фам Т.Х.Ж. Два новых для Вьетнама вида Lepiota (Lepiotaceae, Basidiomycota) из национального парка Катьба. При изучении материалов, собранных в тропических дождевых лесах национального парка Катьба во Вьетнаме, были обнаружены два вида рода Lepiota: L. erythrosticta и L. omninoflava. Оба вида указаны как новые для Вьетнама. Lepiota erythrosticta относится к секции Stenosporae, обладает шипованными базидиоспорами и пурпурными плодовыми телами. Lepiota omninoflava принадлежит к секции Eriophorae, имеет овальные базидиоспоры и желтоватые плодовые тела. Приведены фотографии плодовых тел, иллюстрации и описания макро- и микроморфологических признаков, филогенетическое дерево и обсуждение родственных видов.
