Descripción

These photos do show a dense patch of "Western Scouringrush", Equisetum hyemale ssp. affine (syn. E. praealtum, E. robustum).
It was taken by Mr. James R. Innis from Harrison, Ohio, USA.
He found this dense population at steep slope close to Dry Fork Creek at Miami Whitewater Forest, Harrison, Ohio.
This site is relatively close to New Haven, Crosby Township, named "Preston, Ohio" in late 19th century.
Naturalist A. P. Morgan found the parasitic ascomycete Stamnaria americana on this kind of horsetail in (the vicinity of) "Preston, Ohio" in 1887 and likely thereafter.
He published description of S. americana Massee & Morgan in December 1902.
The imaged horesetail patch is apparently inhabited by the parasitic kind of fungus, and could well be at same place where A. P. Morgan collected his described types of Stamnaria americana.
He had sent specimen of to naturalist G. E. Massee in UK, who sent back his description with delineations, named as published.

Obviously able to infect the American (plus E Asian?) Equisetum hyemale ssp. affine.
Planted a few rooted shoots of the exotic larger growing relative of native type to see if our type of Stamnaria americana is able to infect and propagate on it.
I did the experimental planting probably 10 years before taking these photos, maybe earlier?, but never found any infection by this ascomycete before.
Now, after some years without controlling i found the quite typical blackening of tissue, telling the successful infection, still there are no visible structures of asexual or sexual reproduction, the epiderm is not broken by the fungus.
We will see if this happens later on, compatibility is not assured at time.
Any questions about ;-)

This is likely the highest, respectively westernmost patch of Equisetum hyemale along the streamlet Laufnitzbach, which is infected by parasitic ascomycete Stamnaria post to intentional infection in winter 1998 by myself. There are smaller occurrences further up the streamlet, but i think free from the fungus.
Further explanation done at report of associated Stamnaria americana.

It is host to parasitic ascomycete Stamnaria americana, the current northernmost occurrence at river Mur Valley known by me, which is spontaneous, but not induced by intentional infection done by myself.

I do think it shall have been in winter 1998 when i transferred infected horsetail shoots from another patch close to river Mur into horsetail patches along streamlet Laufnitzbach.
So this intentional infection is the cause of the ascomycete's presence in so named Laufnitzgraben.
For what reason i did so?

1, A large horsetail occurrence at river Mur with the parasitic fungus had been illegally largely destroyed in 1995, so i wanted to save the fungus' presence to the region.

2, I wanted to prove possibility of intentional infection, which may explain nowadays distribution of Stamnaria americana, and apparent low potential of far distance propagation by spores.

I took a large collection at site, numbered as "E. Gruber Fu20-02", saying my 2nd collection of fungi in 2020. This one is going to be shared to several institutions, respectively herbaria in near future. See as well this Flickr photo
I do intend to have this collection shared within exsiccatum series of "Mycotheca Graecensis", distributed from herb. GZU, respectively Institut für Botanik, at Karl-Franzens Universität in Graz, Steiermark.

Report of my collection done on 9th of November in 1994 at very same place, where i had found Stamnaria americana the first time on 3rd of February 1994. This collection had been distributed from herb. GZU in 1995 to other institutions.

My first sampling in February had been destroyed, as i left horsetail shoots full of ascomata within a plastic bag. Mould fungi had done much damage to ascocarps, thus i threw away my first collection. Having learned, never to leave samples in such bags.

Unfortunately i had no camera that time to take photos, could just add newly taken ones at same place.

Occurrence of the fungus the most likely caused by intentional infection with material from another source farther south, where the horsetail and fungus had been largely devasted in 1995. So the northernmost occurrence of the fungus in Styria known to me, had been caused 1, to save the species in the region, 2, to prove chances of intentional infection. I didn't note the year and exact time when i infected this population of Equisetum hyemale, sorry.

Descripción

Report of collection done by late Prof. Josef Poelt from University Graz, together with R. Moberg on 25.07.1976 at Samnaun Mountains, Noth Tyrol, Austrian Alps.
They found and collected plenty of ascomycete fruitbodies situated at dead remains of Equisetum variegatum at ca. 1950 m altitude. Prof. J. Poelt identified these as "Stamnaria equiseti var."
In course of my master thesis (begun 1994) i found these to be quite different from Stamnaria persoonii, syn. S. equiseti, and other species of the genus, hence chose the provisional, never published name "Stamnaria poeltii".
So this sample from 1976 shall serve as holotype of the species in my opinion. A further reason to honour J. Poelt is, that he did his last excursion together with me, just 5 days before his passing due to heart attack on 03.06.1995.
While this excursion to upper Styria, i found and collected fungi on Equisetum variegatum, which seem to represent the same species S. poeltii.

Dense growth of horsetail close to streamlet Kleintalbach, west of Übelbach. It is host to parasitic ascomycete Stamnaria americana. For many years, i could only find the asexual stage there and in vicinity, reproducing by mitotic Titaeospora conidia, but in autumn 2016 the fungus had grown sexual ascocarps. I do not know the reason for this change, liked to know what had happened.

Descripción

Sexual ascocarps, so called apothecia growing parasitically on Equisetum hyemale (ssp. hyemale).
First find of generative propagational stage = Teleomorph, of this fungus at this location after 20 ys of controlling, before that i could solely find the asexual stage = Anamorph, so called Titaeospora [equiseti] there.
Explanation: asexual reproductive stage named "Titaeospora equiseti" in strict sense (so far used at all) shall belong !either! to Stamnaria persoonii (in strict sense), !or! to St. mougeotii (named by me, but never pulished). T. equiseti has formally been synonymized with St. persoonii, but this is not necessarily correct.
Since that, this type of mitotic conidia is better named just Titaeospora without further specification.

? Old but new report ? of this parasitical ascomycet from this area in Kleintalgraben.
I guess to have controlled infected horsetail populations between Übelbach and this location at least 10 maybe 20 times to find ascocarps during past 20 years.
As result i solely found the asexual Titaeospora stage, looking quite similar, but without those yellow fruitbodies called apothecia. Thus i might have bet these would never occur there, got no explanation why the fungus could change to sexual reproduction now. Funny but true, i always was sure this should be Stamnaria americana, speculating the fungal population could miss the afforded crossing type, or had lost ability of sexual reproduction. When arriving there for documentation of the "asexual" type i was truly irritated but as well delighted by this unexpected change!

The host plant, and it's specialized, co-evoluted fungus could survive along the river and some contributing creeks, despite river Mur is heavily regulated and dammed for several power stations.

Solely two, nearby invisible cormorants remained at beech trees close to steep bank of river Mur. All branches and twigs of both resting trees are bright white from the birds' constant droppings.
As fishermen are allowed to repell and i think to shoot cormorants, some birds left the beeches, had no chance to take photos of flying birds.

For that reason i added the report of it's feeding fern. No, i did not want to take a photo of the tiny leaf hopper, just happened occasionally.

As commented later on, my identification is temptative, far from being confirmed by essential visible characters. I hope to get there soon for taking individual cicadas and usable photos of.
