Claviceps, Aspergillus, morels and Neurospora are all in one class of fungi.
Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
Claviceps, Aspergillus, morels and Neurospora are all in one class of fungi. Which class is it, and why is it called the sac fungi? What are its asexual spores called, and where are they made? What are its sexual spores, and where are they made?
Need a reminder? The key ideaShow
Phycomycetes: aseptate, coenocytic mycelium, zygospores (Mucor, Rhizopus, Albugo). Ascomycetes, the sac fungi: septate mycelium, conidia, ascospores in asci (yeast, Penicillium, Aspergillus, Claviceps, Neurospora). Basidiomycetes: basidiospores on basidia (Agaricus, Ustilago, Puccinia). Deuteromycetes, the imperfect fungi: only the asexual stage is known (Alternaria, Colletotrichum, Trichoderma).
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. The class. The Ascomycetes.
Step 2. The name. The sexual spores are made inside sac-like asci, so they are the sac fungi.
Step 3. Asexual spores. Conidia, made on the outside of special hyphae called conidiophores.
Step 4. Sexual spores. Ascospores, made inside the asci, which lie in fruiting bodies called ascocarps.
Answer: Ascomycetes; conidia on conidiophores; ascospores in asci, inside ascocarps.
