The Brook Floater (Alasmidonta varicosa) is a species in the genus Alasmidonta. It is currently classified as Vulnerable on the IUCN Red List. Native to North America, inhabiting ecosystems characteristic of the region.

Symphytocarpus amaurochaetoides is a myxomycete (slime mould) producing dark, clustered sporangia on decaying wood and plant debris in forest environments. It belongs to a group of organisms that alternate between a motile, feeding plasmodium and a reproductive sporangial stage. Like other myxomycetes, it contributes to microbial ecology by feeding on bacteria and detritus in woodland habitats.
