“… hardwood trees…”

seems to support “elegans”, as the other likely candidate, M. borealis, is listed as inhabiting coniferous surroundings.

Damon’s link (see comment directly below this comment) includes a pic of M. elegans hyphae. Looks like a decent match for the segmented piece seen in VJP’s photo seen here. Bryoglossum gracilis is listed as favoring moss. Bessette/B/F includes an account of M. lunulatospora. It is described here as having cap not vivid yellow or orange.

The oversized cap Mitrula seen here appear to be a rarity. I think “elegans” may be a best fit.

For a reverse deja vu read the comments within the link below.

maybe too in depth, but interesting paper…

There are tons of these in standing water in boggy ditches along Frenchman’s Hill West and Frenchman’s Hill roads (sub-division)on Mount Desert Island in Hancock County. I’ve been watching them all week, wondering what they could be. The nearby trees are mixed conifer and deciduous but mostly rotting spruce and balsam I think. The ones I’ve seen are the skinny ones, and look like the examples of mitrula elegans.

within his comments under “M. abietis.” M. borealis and M. lunulatospora are each listed as possibly having “crescent shaped spores.” I found a bunch of what I called M. elegans last week… also fruiting from water submerged leaves. My spore pic is only 400x, but it’s detailed enough to see that some of the spores appear to be crescent shaped.

Redhead, S. A. 1977. The genus Mitrula in North America. Canadian J. Bot. 55: 307-325.

I think they’re just large specimens of elegans.

Wow! Wait a second. Just now saw that posed pic with the small and large together. Those are huge! Downgraded my proposal to “promising.” What else can they be besides elegans? Only look alikes listed in my literature grow in PNW.

Anyone know a good resource for Mitrula identification?

Habitat: side of a dirt road in a runoff pool that had leaf litter from hardwood trees in it.

Mitrula elegans are everywhere right now. These were huge compared to them.

Nice find, VJP.

What was the habitat like?
