Dr. James Kimbrough of the University of Florida will continue his electron-microscopic studies of fungi of the orders Pezizales and Tuberales in order to improve recognition of the genera and families constituting these orders and to begin determining the evolutionary lineages among these saprobic and mycorrhizal organisms. Tuberales includes the well-known edible truffles, species of which have evolved a subterranean existence through a mycorrhizal attachment to the roots of host trees. Dr. Kimbrough's fine-scale analysis of developmental and microchemical features of the spore-discharge apparatus of these fungi is providing data showing the phylogenetic linkage of these subterranean organisms to better-known aboveground cup-fungi. His work will test theories about the evolution of hypogeous (belowground) truffle taxa from the more numerous epigeous (aboveground) taxa of Pezizales, particularly the likelihood that several parallel occurrences of this peculiar subterranean mode of life have evolved among ascomycete fungi.

佛罗里达大学的James Kimbrough博士将继续他对Pezizales目和Tuberales目真菌的电子显微镜研究，以提高对构成这些目的属和科的认识，并开始确定这些腐坏菌和菌根生物的进化谱系。块菌属植物包括众所周知的可食用松露，其中一些物种通过菌根附着在寄主树木的根部而进化成地下存在。金布罗博士对这些真菌孢子排出装置的发育和微化学特征进行了精细分析，提供了数据，显示这些地下生物与更知名的地上杯状真菌之间的系统发育联系。他的工作将检验有关地下（地下）松露分类群从Pezizales更多的地上（地上）分类群进化而来的理论，特别是这种特殊的地下生活模式在子囊菌真菌中进化的几个平行事件的可能性。
