ABSTRACT

We studied species of Leucoagaricus and Leucocoprinus collected in the Dominican Republic over the past 10 years using morphological and molecular methods and carefully compared our collections with previously described neotropical taxa. Twelve new species, eight in Leucoagaricus (La. bulbiger, La. caeruleovertens, La. margaritifer, La. pegleri, La. roseovertens, La. silvestris, La. stillatus, La. turgipes) and four in Leucocoprinus (Lc. antillarum, Lc. fuligineopunctatus, Lc. microlepis, Lc. scissus) are described. Additional records of previously described taxa are also discussed, including the first molecularly annotated occurrences of Lepiota guatopoensis, Lepiota mucrocystis, and La. rubroconfusus in their putative natural habitats and of Lc. cretaceus in the neotropics. Lepiota guatopoensis and Lepiota mucrocystis are transferred here to Leucoagaricus based on their phylogenetic placement and morphological characteristics. Color photographs of fresh basidiocarps and line drawings of microscopic characters are provided for all species.

摘要

我们使用形态学和分子学方法研究了多米尼加共和国在过去10年中收集的Leucoagaricus和Leucocoprinus物种，并将我们的收集物与先前描述的新热带类群进行了仔细比较。十二个新物种，八Leucoagaricus（路易斯安那bulbiger，香格里拉。caeruleovertens，香格里拉。margaritifer，香格里拉。pegleri，香格里拉。roseovertens，路易斯安那silvestris，香格里拉。stillatus，香格里拉。turgipes）和四个Leucocoprinus（LC。antillarum十分LC描述了fuligineopunctatus，小隐孢子虫，剪形杆菌。还讨论了先前描述的分类单元的其他记录，包括首次出现的分子注释的假定的自然栖息地和Lc中的番石榴Lepiota guatopoensis，Lepiota mucrocystis和La.rubroconfusus 。cretaceus在热带地区。环柄菇guatopoensis和环柄菇mucrocystis在这里转移到Leucoagaricus根据自己的系统发育位置和形态特征。提供了所有物种的新鲜紫皮果的彩色照片和微观特征的线条图。
