Using a Microscope to Study
|Podostroma alutaceum is a synonym. This mushroom belongs to a class of
fungi known as Ascomycetes, the sac fungi; and to a particular group called
flask fungi (pyrenomycetes), which includes Xylaria and Cordyceps species.
These fungi develop tiny fruiting bodies (perithecia) that are embedded in
what George Barron calls "a massive fungus matrix", the stroma.
