Here, they crawl along the mountainsides, searching painstakingly for tiny, dark brown protrusions from the soil. These stalks are not plants, but a rare <a href=\"https:\/\/www.sciencedirect.com\/topics\/medicine-and-dentistry\/cordyceps\">fungus<\/a>, locally known as <em>yarsagumba, <\/em>meaning \u2018summer grass, winter worm\u2019.<\/p>\n\n\n\n<p><em>Ophiocordyceps sinensis<\/em>, also known as caterpillar fungus, is a type of parasitic fungus that infects caterpillars underground.

Used in traditional medicine, demand for the fungus has <a href=\"https:\/\/www.nature.com\/articles\/482035b\">skyrocketed<\/a> in the past 20 years \u2013&nbsp;and so has the price.<\/p>\n\n\n\n<div class=\"wp-block-cd-accordion block--accordion\"><span class=\"block--accordion__title\">The lifecycle and use of cordyceps<\/span><div class=\"block--accordion__content\"><div class=\"block--accordion__content__inner\">\n<p>In autumn, caterpillars become infected with fungal spores.
