Hypogeous fungi ("truffles") are challenging to study because they produce underground sporocarps that may not be located during traditional fungal surveys. Commercially valuable truffles are located using scent-detection dogs trained on truffles. However, the dogs are not necessarily limited to commercial truffle species when trained on other taxa of interest. For example, (Pyronemataceae, Ascomycota) is a genus of common but difficult to find truffles that develops small and often soil-colored hypogeous ascomata. We used a truffle dog trained to locate sporocarps in the southern Willamette Valley and associated mountains in western Oregon, USA, recording when the sporocarps were present at a wide range of elevations (113 to 1879 m). We found was present in half of our surveys and noted that it rarely fruited in areas that had experienced wildfire. This study demonstrates the value of using truffle dogs in documenting truffle diversity, particularly those that are difficult to locate visually, and provides further evidence for the abundance of .
地下真菌（“块菌”）的研究颇具挑战性，因为它们产生的地下子实体在传统真菌调查中可能难以被发现。具有商业价值的块菌是通过用块菌训练过的气味探测犬来定位的。然而，当用其他感兴趣的分类群进行训练时，这些犬类不一定局限于商业块菌物种。例如，（火丝菌科，子囊菌门）是一类常见但难以找到的块菌属，它们会形成小的、通常与土壤颜色相近的地下子囊果。我们在美国俄勒冈州西部的威拉米特河谷南部和相关山脉使用了一只经过训练来定位子实体的块菌犬，记录了在广泛海拔范围（113至1879米）内子实体出现的时间。我们发现，在我们一半的调查中都有出现，并注意到它在经历过野火的地区很少结果。这项研究证明了使用块菌犬记录块菌多样性的价值，特别是那些在视觉上难以定位的块菌，并为的丰富度提供了进一步的证据。
