Document Summary
Periphyses: hyphae in the ostiolar canal of an ascocarp. Order hypocreales: pale to brightly colored perithecia. Has stroma/stomata: compact mycelium w spore bearing structure embedded/on top. Hypocrea: found on decaying wood, bark and leaves. Lobster mushroom: parasitizes mushrooms in early part of their development. Has sexual (fruiting body) and asexual state (mycelium) Trichoderma: soil fungus that is an important mycoparasite. Saprobes and parasites (common parasite on dead branches) Beech bark disease = beech + scale insects + fungal pathogen. Anamorphs of hypocreales = important plant pathogens. Produce mycotoxins in cereal crops that can affect animal and human health. Infections can occur in humans with normal immune systems (can occur in nails and cornea) Agent green (fusarium oxysporum): plant disease that causes wilting, yellowing and death. Government tried to use this to counter the war on drugs in columbian and andean countries. Cordyceps: parasitizes insect larvae and fungal fruiting body.
