Mycelial morphology, mitospores and primordium formation of Simocybe sumptuosa in laboratory cultures

In laboratory cultures Simocybe sumptuosa produces tiny slime drops with cu rved, binucleate conidia and ellipsoid, terminal or fusiform intercalary, b inucleate chlamydospores. Chlamydospores occur also within the agar medium, but conidia do not. Noduli also form, and in one culture a few basidiomes developed The mycelium is significantly denser beneath the noduli than betw een the noduli. Carpogenesis has been studied using stained microtome secti ons. Simocybe sumptuosa is exocarpic amphicleistoblemate.
