At branches of Equisetum hyemale ssp affine, planted within native host population.
Further information provided at prior observations of Equisetum hyemale ssp. affine and Stamnaria americana.
The small holes in dead shoot segments of branches look as if the fungus had grown some propagational stage, asexual Titaeospora conidia, sexual ascocarps, or both.

Descripción

The large population of dense mats of Equisetum hyemale growing along river Mur in alluvial woods is well infected by the parasitic ascomycete Stamnaria americana.
I took photos of obviously infected, there planted, alien Equisetum hyemale ssp. affine, which is native to North America, but frequently planted at ponds. It was planted by me some years ago, to prove compatibility to native type of Stamnaria americana.
Whilst the native horsetail had grown ascocarps in winter, the exotic relative showed only blackened shoot segments as typical in case of infection, but no stage of propagation.

Imaged ascocarps are not at best stage. The photos were taken to demonstrate infection of several years ago planted American Equisetum hyemale ssp. affine with Stamnaria americana. While the larger exotic type of horsetail showed just blackened shoot segments, but no kind of reproduction stage of the fungus, the native kind had clearly grown now aged ascocarps in winter. Thus this observation was a welcome and useful catch by.

Descripción

American type, resp. subspecies of Equisetum hyemale, plantet several years ago inmid of native, nominative type, infected with Stamnaria americana.
The exotic type developed well, spread along a line of estimated ca. 15 m, but not circular. Aerial shoots about twice as high as ssp. hyemale, highest seen ca, 1.8 m without branches. In width they are about three times, or even more wider. Just a few, but segments are blackened as usual with infection by Stamnaria, however, neither asexual conidia, nor ascocarps are present.
This could mean that the local type of Stamnaria americana may successfully infect the alien type of horsetail, still fails in propagation thereafter. In this case there is more difference between both, horetails and parasitic ascomycetes from both continents. Sure this needs further proving true to get sure.

At artificial ponds close to the river power weir at the former bed of the river. Those ponds have likely been made as kind of "ecologic compensation" for destroyed natural habitats as i do assume.
The horsetail has either been intentionally planted at shore of the pond, or was brought to there by other plantings.

My first find and photos of Stamnaria on this horsetail population of apparent Equisetum × moorei which i know since 1994.
It is close by a large population of Equisetum hyemale infected constantly by Stamnaria americana, not far from the place where i found the fungus for the first time at begin of February 1994.
However, i never found S. americana at the hybrid horsetail, but only on Equisetum hyemale, and it seems to be fixed to as sole host species.
Today i found plenty of bright yellow ascocarps on the hybrid, rising the question: May S. americana bear fruitbodies on E. × moorei (or perhaps E. ramosissimum), or is this new find in fact Stamnaria laetissima (Cesati 1846) comb. ined. ?
I need to clear specific ID of the fungus on reason of characters of asci and spores as soon as possible.

Stamnaria laetissima (Cesati 1846 in exsiccatum) comb. ined., on Equisetum ramosissimum at southern part of the railway station Hohenau an der March. Just a minor part of the relatively large and partially dense horsetail population appeared to be infected and bore sexual ascocarps and asexual conidiomata on 22.08.2020.

When taking the first added photo i was not aware of the hidden, parasitic ascomycete for which i was seeking. Some minutes later i found the fungus close by. Later, when watching this photo, i saw the orange coloured fruitbodies, but when taking it, i thought the fungus was missing at the site.
This is one reason why such fungi are commonly not seen despite their presence, but who looks for at all?
"nerdy" people like me.

At and between "ecologic compensation ponds" which were made close to the river power weir, where the river Mur was before. Either rhizomes of the horsetail had been transported with material to there, or it had sown from a large, old clone at railway embankment close by. But i got severe doubts such new growth could ever spread and grow that rapidly.
I looked for signs of infection by some parasitic kind of ascomycete genus Stamnaria, but couldn't find any convincing, so it is apparently (still) free from.

Apparently the hybrid Equisetum × moorei, but not pure species E. ramosissimum. This year the embankment and electrical overhead line including supports had been renewed, trees and bushes removed. Prior to that, the horsetail population grew as well more close to the railway, still it recovered remarkably well.
I never found Stamnaria americana at the apparent hybrid horsetail, although the fungus is permanently inhabiting a large popuation of Equisetum hyemale right at the other side of the bankment. Just a few minutes after taking this photo, i found plenty of bright coloured fruitbodies of some Stamnaria sp. on this horsetail. Since i solely proved S. americana to inhabit and fructificate on E. hyemale, i doubt it shall be the same species here.
May there be the still unpublished Stamnaria laetissima (Cesati 1846, in exsiccatum) comb. ined., which i found a few days ago twice in Lower Austria, Niederösterreich, who knows? I need to prove specific characters of asci and spores by a microscope.

A large, old clone, growing in dense mats at the railway embankment in Wannersdorf, Frohnleiten.
This population spreads more than 300 m along the railway tracks and embankment. I do know it at least since 1994 in case not longer, but could never find any parasitic kind of ascomycete genus Stamnaria growing on shoots. It has been at least superficially devasted several times whilst railway renovations, as tracks and gravel were exchanged, however the horsetail will always revover easily from remained rhizomes. Now, as i found other horsetail populations infected with Stamnaria, i controlled here again. It still appears free from such fungi.

However, the major part of the relatively large population of Equisetum ramosissimum appeared to be free from this fungus on 22.08.2020.
There are dense mats of the Branched horsetail along the railroad tracks and aside at the embankment south to the railway station.

Close E of the Neusiedler See, this kind of horsetail does grow abundant at this area, partially in dense mats.
I could not detect any indication of parasitic kind of genus Stamnaria upon, still might have just not seen or interpreted despite it's presence, who knows?

I revisited this site about 20 years after my first visit. The population looks to have got reduced, growing less of shoots, perhaps smaller in average now.
Again i could not find (indication of) parasitic ascomycete Stamnaria laetissima (Cesati) comb. ined.
I had found some ascocarps of such kind of fungi whilst studies for my thesis on specimen of E. ramosissimum collected near Moosbrunn in 1867 and 1959.
In the meanwhile occurrences of the horsetail might have got reduced, and S. laetissima have vanished. But there could be other occurrences in the region.
