Examples from the Web for hypothallus
The hypothallus is sometimes noticeable under some of the sporangia where closely crowded, but is not a constant feature.

The hypothallus is quite distinct, extra-marginal, and in substance like to the peridial wall.
Plasmodiocarp very much flattened, longitudinally creeping and reticulate or altogether widely effused; hypothallus none.The Myxomycetes of the Miami Valley, Ohio
