Both of these slime molds require better magnification- the camera on the dissecting scope would allow a much better close up to verify the absence of a stalk. You indicate sporangia in #2, but we can't tell this from the pics given, we would need to see the stalk f rom some angle...and the absence of one in sample #1. I can't read the dark text on this background that is used for references.
ReplyDeleteOVERALL: You have a nice collection; used a lot of mushrooms, which unfortunately had no spore prints, no close ups and all pics are of dehydrated samples; some inconsistency in font size and color between sections; logic behind keying is reasonable, but can't be supported completely with figures used
