Common Pinmould

<em>Mucor mucedo</em>, the common pin mould, is a zygomycete fungus in the family Mucoraceae, belonging to one of the earliest-diverging lineages of terrestrial fungi. It is characterised by long, unbranched sporangiophores topped with spherical, pin-like sporangia that release large numbers of asexual spores, giving infested substrates a grey or white mouldy appearance. The species is a saprotrophic decomposer, typically colonising dung, soil, decaying organic matter, and stored food products, where it plays a role in nutrient cycling and organic matter breakdown. <em>Mucor mucedo</em> is distributed across Europe, with records from Belgium, Denmark, and Norway, and in South America including Brazil, and is likely cosmopolitan given the ease with which its spores disperse through the air. It is assessed as Not Evaluated on the IUCN Red List, as fungal conservation assessments remain incomplete globally. Sexual reproduction involves the fusion of compatible mating types to produce resistant zygospores. Biological traits such as colony growth rates under standardised conditions, typical biomass production, and detailed ecological roles beyond general decomposition remain poorly documented in the scientific literature. The species is non-pathogenic to healthy humans but may cause opportunistic infections in immunocompromised individuals.
