Walt, I also had learned the name…

badioconfusa for the common brown springtime cups. There seems to be some disagreement about whether badioconfusa and phyllogena are different species.

I’m posting a spore pic. Took awhile for this cup to drop any spores. But most of what I see agrees with the descriptions for P. phyllogena and/or P. badioconfusa. Dimensions 18-22 × 7-11 with q~2.7, thick walls that are thicker at the ends, and roughened appearance suggesting “finely warted”. (I’ll be using a better scope soon.) The only thing I couldn’t find are the two oil drops reported by several sources. (One spore in the pic seems to vaguely show two smallish drops.) Kuo does not mention the oil drops, so maybe they’re difficult to detect. Print was translucent whitish.

I’m not sure about any seasonal look-alikes, but going through the Asco book, I don’t see any other good matches.

There is little consensus on P.phyllogena or it is extremely variable. I learned this species as P. badioconfusa. When fresh it usually shows violaceous tints.
