摘要

Hypocopra(Fr.) Kickx is used for those representatives of the Xylariaceae typically possessing sessile, clypeoid, or reduced stromata; asci with a complex apical apparatus staining blue or brick-red in Melzer's reagent; either unicellular dark-walled ascospores or bicellular ascospores with one large dark-walled cell and a very small hyaline cell; and a single germ slit of variable length in the ascospores of the different species. A synoptic key to all currently recognized species is provided. One new combination,H. hypocoproides(Sordaria hypocoproidesSpeg.), is described and illustrated along with fourteen new species:H. annulata, found on deer and moose dung from Sweden and U.S.A.;H. anomalaandH. keniensis, both on burro and cow dung from Kenya and Mexico;H. bicolorandH. cataphracta, both on horse dung from U.S.A.;H. dolichopoda, on horse, cow, deer, and rabbit dung from Canada and U.S.A.;H. elachyglossina, on horse, cow, and goat dung from Bulgaria, Canada, Spain, Sweden, and Yugoslavia;H. festucacea, on red-deer, moose, and wapiti dung from Canada and Switzerland;H. pachyalax, on horse, donkey, and rabbit dung from Canada, Spain, and U.S.A.;H. phorcodes, on burro and cow dung from Mexico;H. planispora, on hare and rabbit dung from Canada, Scotland, and Sweden;H. plinthina, on horse and cow dung from Canada and U.S.A.;H. punicea, on cow dung from Kenya, Mexico, and the Virgin Islands; andH. stephanophora, on horse dung from England and U.S.A.
