Symposium on Higher Fungal Classification: A Contemporary Overview; Tomales Bay, CA; August, 1992

在目前的真菌分类中，担子菌门和子囊菌门是根据“整个真菌”（即营养和生殖结构，后者加权）进行分类的，而后菌门是根据相对较少的、通常是人工的特征形成分类群。这个问题将在研讨会“高级真菌分类”中讨论，托马斯·布伦斯清楚地阐述了这个问题，“如果所有的真菌都可以通过它们的核酸进行比较，并放在一个单一的系统发育树上，我们还需要维持后菌群吗？”显然，从科学的角度来看，答案是毫无保留的“是”。如果担子菌和子囊菌的系统发育已经建立在严格的数据收集和分析方法的基础上，这种无性形式的分类解决方案将是最可行和实用的。美国的许多实验室已经开始了研究，包括对表型的宏观和微观特征的详细分析、分子序列数据和进化算法，以发展这些系统发育；然而，该协议似乎还没有像完成这一努力所必需的那样广泛传播。因此，这次研讨会可能有一个次要的影响——分子技术在真菌王国系统发育关系研究中的持续传播。

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.
