Chytrid fungi reproduce with posteriorly uniflagellate zoospores and are commonly considered limited to aquatic habitats. Yet an abundance of chytrids can be extracted from almost any soil sample where they decay debris and parasitize other microbes. Martha Powell and Peter Letcher, at The University of Alabama, and Joyce Longcore, at The University of Maine, propose to use multigene sequences and zoospore ultrastructural characters to analyze soil chytrids in the Order Spizellomycetales. These researchers will train three graduate students as the next generation of experts in modern methods of chytrid systematics. The need for new experts is great because the last monographic treatment of chytrids is 45 years old and is outdated. Investigators will explore the application of the phylogenetic species concept to spizellomycetalean chytrids. As outcomes of this project, trainees will produce modern monographs of spizellomycetalean genera and descriptions of newly discovered taxa. This project will contribute new sequences of soil chytrids to GenBank, valuable in molecular environmental studies. An expanded Chytrid PEET website will make information and images widely available. PEET trainees will gain new skills in pedagogy and video production, generating learning modules for middle school children that transmit an appreciation for chytrids and fungal biodiversity. The totality of these efforts will make chytrids better known and their identification less problematic, leading to a better understanding of their importance in the environment.

壶菌真菌用后部单鞭毛游动孢子繁殖，通常被认为仅限于水生生境。然而，几乎任何土壤样本中都可以提取大量的壶菌，它们会腐烂碎片并寄生其他微生物。阿拉巴马大学的 Martha Powell 和 Peter Letcher 以及缅因大学的 Joyce Longcore 提议使用多基因序列和游动孢子超微结构特征来分析 Spizellomycetales 中的土壤壶菌。这些研究人员将培养三名研究生作为现代壶菌系统学方法的下一代专家。对新专家的需求非常大，因为壶菌的最新专题治疗已有 45 年历史，已经过时。 研究人员将探索系统发育物种概念在 spizellomycetalean chytrids 中的应用。作为该项目的成果，学员将撰写有关 spizellomycetales 属的现代专着和新发现的分类群的描述。该项目将为 GenBank 贡献新的土壤壶菌序列，这对分子环境研究很有价值。 扩展后的 Chytrid PEET 网站将广泛提供信息和图像。 PEET 学员将获得教学和视频制作方面的新技能，为中学生制作学习模块，传达对壶菌和真菌生物多样性的认识。这些努力的总和将使壶菌更加为人所知，并减少其识别问题，从而更好地了解它们在环境中的重要性。
