not collect any specimens for this observation or observation 196253.

There were definitely no willows in the immediate area. Just Quercus agrifolia, Umbellularia californica. And Toxicodendron prominent in understory.

MO helped establish that ochraceous staining and black fibrils on the stem..

are not enought to characterize protecta (see “sp-C18”), to be considered as a candidate for protecta those characters should be present (so far as is known) in mature material. Hence, I am not confident that protecta would be our final determination in this case.

Is it correct that there is no dried specimen? Based on recent discussion on MO, I also would like to know if there were willows (perhaps small ones) present at the collecting site?

Very best,
