I’m confused too. Quote from Zhong and Pfister: “Phylogenetic analysis of the sequence data indicates that L. viscosa, L. lubrica and L. atrovirens are polyphyletic species”. I think they mean polymorphic (a single species can’t be polyphyletic..).
The Leotia lubrica I know, is usually growing in damp and rich forests, often many together and they are brownish yellow, head and stem are the same colour. I have only seen green-headed ones in a completely different environment, a strongly calcareous lawn. I don’t know if they are different species, or if it’s the habitat that gives them different colours?
To get to the fresh specimens you look for bumps in the sand and then dig them up. They are scattered with more then two together rare. In sand with almost no vegetation. We do find all the other forms during the warmer months of the year.
The color of the image shown is very unusual for other Leotia sp. but it is always this color, top to bottom.
that these three morphological species are polyphyletic? Or as I interpret their situation as described, they did not evolve from a common ancestor? So there may be more than three common species or maybe even genera!!? If so, I’ll stick with the morphological species concepts. Maybe I am misunderstanding the meaning of monophyletic.
I was interested in John Steinke’s report that Leotia lubrica fruits in Oct. and Nov. in Wisconsin. In Ohio this is a common summer species with very few found by Oct.
pull-quote from Leotia DNA paper by Zhong and Pfister:
“Based on our analyses none of the three morphologically defined species, L. lubrica, L. viscosa, and L. atrovirens, were monophyletic . . . our studies indicate that there may be more genetic variation among Leotia collections than is commonly recognized.”
Zhong, Z. and D. H. Pfister. 2004. Phylogenetic relationships among species of Leotia (Leotiales) based on ITS and RPB2 sequences. Mycological Progress. 3: 237-246.
It often shows up at walks in piles of collections in New England. I’ve stumbled across flushings of it carpeting the forest floor for yards and yards. I’ve also noticed that the ‘heads’ of them are found across a continuum of yellow to green color, making me skeptical of the distinction between L. lubrica and L. viscosa.
is common in northern California.
This is a common species in the sand blows near the Wisconsin River. It fruits in October and early November. It can fruit by the thousands just pushing the sand up to expose the fertile head. I have not seen this described in any papers and this image you have is the first I have seen out side of Wisconsin.
Is there any collection info?
The head does not look green enough to me for the typical Leotia viscosa that I see. The mushroom also does have some green in it. I think it may be Leotia lubrica that’s just starting to get attacked by another fungi.
A california version? Looks mighty pale to me.
fruit body on R is Leotia viscosa.
