A neat black cup found by Else Vellinga. Didn’t get a chance to put it under a scope to even get it to genus. They were about 2cm across.
Macroscopically it looks similar to Doug Smith’s Pseudoplectania nigrella, but that comes from the Sierra Nevada in the spring whereas this is from coastal California in the winter.
Here’s something to consider: Pseudoplectania nigrella — obs 1297. But I guess there is also, Plectania melastoma. But these look like P. nigrella.
Although I’m not sure about the details on what makes each of these species what they are…
