Document Summary
Asci are unitunicate (inner and outer ascus walls do not separate during ascospore release) Spores are released explosively through ascus tip. Release through specialized adaptation at ascus tip. Sterile cells are associated with the hymenium. Periphyses: hyphae in the ostiolar canal of an ascocarp. Asci have thin refractive apical ring, one or two celled ascospores with appendages or sheaths. The members of this order are not economically important but they are important experimentally (they are easy to grow) Soft textured, usually pale to brightly colored perithecia. Contains 3 families which are determined by molecular studies and ascocarp anatomy. Members of this order are mycoparasites that parasitize other fungi. Hypocrea: has cushion shaped or spreading fruiting bodies and surrounding tissue. Can parasitize amanita when they are young. Produces chitinases which helps with biological control of mushrooms but can contaminate mushrooms we want to grow.
