Lichens are a symbiotic relationship between fungi and either algae or photosynthetic bacteria (cyanobacteria). How could you determine if the photosynthetic component in the lichen you are studying is algae or cyanobacteria?

Imagine that you are the first scientist to observe lichen microscopically. What observations would lead you to conclude that the lichen is composed of a fungus and an algal species?

Basidia within a basidiocarp are obvious for mushrooms, but this may not be as obvious for other examples that you have observed. For each of the examples of basidiomycetes that you have observed, speculate about the location of structures analogous to the basidia observed in mushrooms. Think about the formation of spores by meiosis

Traditionally, the classification of fungi has been based on the nature of sexual stages of the life cycle. For Penicillium, however, no sexual stages of the life cycle have been observed. Without evidence from sexual stages, speculate about other possible sources of evidence that scientists may use in classification.

Refer back to the description of Pilolobus. Speculate about the adaptive advantage of having a system to propel sporangia, as seen in Pilolobus.
