Since December 2019, a de novo pattern of pneumonia, later named coronavirus disease 2019 (COVID-19), has caused grave upset throughout the global population. COVID-19 is associated with several comorbidities; thus, preventive and therapeutic strategies targeting those comorbidities along with the causative agent, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), seem imperative. In this state-of-the-art review, edible and medicinal mushrooms are featured in the treatment of SARS-CoV-2, COVID-19 pathomanifestations, and comorbid issues. Because this is not an original research article, we admit our shortcomings in inferences. Yet we are hopeful that mushroom-based therapeutic approaches can be used to achieve a COVID-free world. Among various mushroom species, reishi or lingzhi (Ganoderma lucidum) seem most suitable as anti-COVID agents for the global population.
