Thanks for shining a light on this one. S. neesii isn’t a name familiar to me for North America, but it does seem to explain the coloring. I’ll make a point to visit the site this year to collect and get some spore measurements to verify.

Thanks again, Nicolas

I have always used the name Spathularia rufa because that’s what it has been called in my swedish books.

Lately, I have tried to find out what S. rufa really is.. I saw one comparison (forgot where) between flavida(pale yellow) and rufa(darker yellow). I wonder if that rufa actually was a Microglossum?

When Nees published rufa he only referred to Schmidel, but I can’t find Schmidel’s description (or icon?). I’m not sure it’s validly published anyway..

Not S. flavida

Dear Drew, dear Irene,
I’m quit sure this is not S. flavida, although it could be difficult to identify young specimens due to their very light yellowish color.
I think this collection is S. neesi Bres. [syn. S. rufa Nees, syn. S. alpestris (Rehm) Rahm]. This species presents apothecia very compressed, never yellow. Spores are usually smaller than in S. flavida.
The genus Spathularia needs a serious revision.

I glanced through Mains’ report in Mycologia. He didn’t seem to take much notice about colours at all, with flavida ranging from yellow to cinnamon-buff.
He was still able to describe a handful of varieties of flavida, mostly based on different looks on spores. He also reduced a couple of earlier described species to varieties of flavida – seven varieties together.

Some studies have been done since the DNA era started that show parts of a larger picture. Cudonia and Spathularia in different clades and so on, but they also show collections labeled Spathularia flavida in different lineages.
I haven’t seen anyone try to sort out the genus Spathularia with the help of DNA yet.

Thanks Irene

True enough about “flavida”. However, is color variation sufficient to separate species? My understanding is that Mains believed the differences were not significant enough. Of course, he might have been mistaken…I don’t know. But somebody has to look into it don’t they? Perhaps Spathularia flavida grp. would make more sense.

Beautiful picture

but I don’t approve of the name flavida..
(flavida means yellow)
