Measurements

OG = oogonium diameter

OS = oospore diameter

OP = ooplast diameter

OT = oospore wall thickness

AO = distance between origin of antheridium and oogonium

HD = hyphal diameter

Oospores with multiple antheridia
Oospore with intercallary antheridium

Vesicles at various stages of zoospore differentiation.
Terminal oogonium and an antheridium originating from the same hyphae = monoclinous.
Spherical sporangium
Slightly irregular oogonium
Aplerotic and Plerotic
What are these

What the...? What are these thingies? Are they sporangia, chlamydospores... ? I don't know what they are.
