A new facility to study fungal and lichen systematics is proposed. This facility will be novel because it will retain the classification aspect of traditional herbaria but eliminate duplicate specimens (except type specimens and rare species) so that excessive growth beyond the capacity of the space provided will be prevented. The facility will include a temperature controlled incubator for fungal cultures that, when mature, will be dried in an adjacent oven, and stored in metal herbarium cabinets.  Microscopes will be available for the users of the facility and a digital camera will be used to store and manipulate images of fungi and lichens on a PC computer. These images will serve as research vouchers for species that are difficult to culture and maintain, and they will be highly valuable for HQP training of groups of fungi and lichens that are rarely observed in nature. This will also provide reliable access for the scientific community to find information on hard-to-culture organisms and associated data. Studies of fungal and lichen biodiversity, using inventories of species, variation in genes and secondary metabolites, mobile elements, and gene regulation, are essential for understanding ecosystems from the molecule to morphology. Appropriate storage of these specimens will preserve the morphological features for taxonomy, and the DNA and secondary compounds for studying population and evolutionary variation. Other studies using the well preserved specimens may lead to an understanding of the movement of mobile elements and the spread of plant disease, or gene regulation in medicinally and ecologically important secondary compounds.

提出了一种新的真菌和地衣系统学研究设施。这一设施将是新颖的，因为它将保留传统草本植物的分类方面，但消除重复标本(模式标本和稀有物种除外)，从而防止超出所提供空间的过度生长。该设施将包括一个可控温的真菌培养箱，成熟后将在相邻的烤箱中烘干，并储存在金属标本室的橱柜中。该设施的用户将可以使用显微镜，并将使用数码相机在PC电脑上存储和操作真菌和地衣的图像。这些图像将作为难以培养和维护的物种的研究凭证，对于自然界中很少观察到的真菌和地衣种群的HQP培训将具有极高的价值。这也将为科学界提供可靠的途径，以找到关于难以培养的生物体和相关数据的信息。利用物种清单、基因和次生代谢物的变异、可移动元素和基因调控来研究真菌和地衣的生物多样性，对于从分子到形态的生态系统的理解是必不可少的。这些标本的适当保存将保存用于分类的形态特征，以及用于研究种群和进化变异的DNA和次生化合物。使用保存完好的标本进行的其他研究可能会有助于理解可移动元素的移动和植物病害的传播，或者在医学和生态上重要的次生化合物中的基因调控。
