In the present classification for fungi, the Basidiomycota and Ascomycota are classified on the basis of the "whole fungus" (i.e., the vegetative and reproductive structures, with the latter weighted) whereas the Deuteromycota were form taxa based on relatively few, usually artificial, characters. This problem, which will be addressed in the workshop, "Higher Fungal Classification," was clearly enunciated by Thomas Bruns, "If all fungi can be compared through their nucleic acids and placed on a single phylogenetic tree, do we need to maintain the Deuteromycetes?" Clearly from a scientific perspective the answer is an unqualified "yes. This taxonomic solution for these asexual forms will be most feasible and practical if the phylogeny of the basidiomycetes and ascomycetes has been solidly based on rigorous methods of data collection and analysis. Various laboratories in the U.S.A. have initiated studies that incorporate detailed analyses of macro- and microcharacters of the phenotype, molecular sequence data, and cladistic algorithms to develop those phylogenies; however, it appears that protocol has not spread as widely as is necessary to complete this endeavor. Therefore, this workshop could have a secondary effect---the continued spread of molecular techniques in the study of phylogenetic relationships within the fungal kingdom.

在目前的真菌分类中，担子菌门（Basidiomycota）和 子囊菌门基于“全真菌”（即， 营养结构和生殖结构，后者 加权），而半知菌门是基于 相对较少的，通常是人造的，字符。 这个问题， 这将在研讨会上讨论，“高等真菌 托马斯布伦斯清楚地阐述了“如果所有 真菌可以通过它们的核酸进行比较， 单一的系统发育树，我们是否需要维护 半知菌？“从科学的角度来看， 是个绝对的“是” 这种无性繁殖的分类学解决方案 形式将是最可行的和实际的，如果 对担子菌和子囊菌的研究一直基于严格的 数据收集和分析方法。 各种实验室， 美国已经开始了研究， 宏观和微观性状的分析， 序列数据，以及开发这些数据的分支算法 然而，协议似乎并没有随着 这是完成这项奋进所必需的。 因此本 研讨会可能会产生次要影响-继续传播 系统发育关系研究中的分子技术 在真菌王国中。
