Zygospores of A: Cokeromyces recurvatus, B: Cunninghamella homothallicus, C: Radiomyces spectabilis and D: Absidia spinosa. E: Hesseltinella vesiculosa sporangia. F–G: Mortierellales (Mucoromycota). F: Mortierella (Gamsiella) multidivaricata chlamydospore. G: Lobosporangium transversalis sporangia borne on arachnoid mycelium. H–J: Zoopagales (Zoopagomycota). H: Piptocephalis cormbifera immature sporangia. I: Syncephalis cornu sporophore bearing senescent sporangia with uniseriate sporangiospores. J: Rhopalomyces elegans fertile vesicle with monosporous sporangia. K: Basidiobolus ranarum monosporous sporangium. L: Dimargaritales (Zoopagomycota), Dispira cornuta two-spored sporangia. M–O: Kickxellales (Zoopagomycota), monosporous sporangia of M: Spiromyces minutus, N: Linderina pennispora and O: Kickxella alabastrina. Scale bars: A–F, I–O = 10 µm; G, H = 20 µm.
