Spumatoria longicollis

Found on cow dung.
A different find than the one from 291112 which was on horse dung, but it is in the same area.
Cow dung is from Galloway cattle, the horse dung was from Iceland pony's.
Finding is confirmed by David Malloch.


The neck is covered by longitudinal hyphea, 293x25.5 um, the beak constist of the same clustered hyphea
The perithecia: 112.5 um in diameter.


No asci found yet, but the species are abundently present so I can wait till they are ripe enough.
Spore measurement 24.57x5.6 um on a single spore, containing one septa and oil drops. Immature spores filled with numerous small oil drops.

récolte correspond !

Re : Spumatoria longicollis
These collections, including the one of Michel at http://www.pilzforum.eu/board/thema-spumatoria-longicollis, seem very close to species of the genus Kathistes.  The attached photos are of Kathistes calyculata, collected on moose dung in New Brunswick, Canada. If anyone has recent material of S. longicollis I would be very grateful to receive a few perithecia for sequencing.

The panel in the right of the photo show one sporidioma of K, calyculata.  The function of these structures is unknown, but they seem to be a constant feature of species of Kathistes.

Re : Spumatoria longicollis
Yes, like Michel says, I also think you've found another time the rare Spumatoria longicollis!
Very nice found, Joop!
We discussed it three years ago here:

Dave, you wrote about Kathistes calyculata.

I've never heard about this species!!!
But it seems very closely to Spumatoria.
In 1990 you published this species in Can. J. Bot. 68(8).

It would be very great, if you would send a PDF to compare!

Thanks in advance.

Thank you very much.

Re : Spumatoria longicollis

Here we have the asci.
The ascus has the shape of a waterbag like the one they use during a camel ride.
It has two extension of which one is extending in water, when young it only has one.
Containing 8 spores in 2 bundles of 4.
Young ascus: 58.6x21.2 um.
Mature ascus: 80x-29.5 um.


I also observed a perithecia with two necks and another one with a single neck and two beaks.

Re : Spumatoria longicollis
With this ascus- and sporesize and the numerous small oildrops in vital ascospores as well as the missing of sporidiomata this is Spumatoria longicollis.
But interesting to know, that the genus Kathistes is simular to Spumatoria.
We'll do our best to find one or the other species of Kathistes in the future.

And be sure, when I find Spumatoria at the next time, I will send it to you for sequencing, Dave.

Norbert

Hello Norbert,


 


I already did send David about 10 species for sequensing today.

Re : Spumatoria longicollis
Hi Joop and Norbert..

I have had success finding these fungi on dung of moose (Alces alces), but that is because it is the common large animal where I live.  Other dung types are probably just as productive.

Species of Kathistes, Pyxidiophora and Sphaeronaemella are all long-necked ascomycetes common on moose dung. Probably on deer, cow and horse as well. The trick for finding them is to collect dung that is very fresh; probably on the ground only for a day or so. They must have have been visited by insects. Don't dry the dung, but put it directly in a moist chamber for incubation. Don't let it get too warm or Trichoderma will take over. Probably 15° to 18°C is best. Examine with a dissecting microscope at fairly high magnification. Pyxidiophora species will have prominent anamorphs that may offer a sign of their presence.

Good luck in your searches for these interesting ascomycetes!

Re : Spumatoria longicollis

Hello David,


Good to know that the dung has to be very fresh. The chunck of cow dung was too fresh so I kept it in a plastic box covered by a transparant lit with a temperature between 16-18 deg. C., and no direct sunlight.
I checked it every two days for pyrenomycetes and the first fungi to appear after one week were Coprinus species mostly C. stercorius, it took 3 weeks before I discovered S. longicollis with 100+ species, together with different kinds of Podospora and Sporormiella species.

The Pyxidiophora basidiorostris and Pyxidiophora spec. I found were problably also produced on very fresh dung.

Re : Spumatoria longicollis

Hello Norbert,


David mailed me that he had found sporidiomata in the surrounding dung.
Compairing the photos he did send me I realized that I found one myself not knowing that it was a sporidioma
