Coronellaria sp. on Schoenoplectus
Chris Yeates, 26-09-2012 22:17
Chris YeatesBonsoir tous
last year I collected what was to me a very puzzling discomycete on damp dead stems Schoenoplectus tabernaemontani. Both Zotto and Stip kindly indicated this was a Coronellaria species, and Zotto further pointed out that he and Torsten Richter had shown that there are two very similar taxa - C. pulicaris and an as-yet undescribed species on Schoenoplectus. At the time the material I had was rather over-mature and it was difficult to check the key differences (particularly presence or absence of croziers).
I recently re-visited the site - the collection spot is close to where this photograph was taken: http://www.ywt.org.uk/reserves/ledston-luck. The locality is a former colliery site at Ledston Luck, near Kippax, West Yorkshire  1°20'53.49"W  53°46'29.16"N ; S. tabernaemontani is generally a plant of coastal brackish sites in Britain, but here it is highly likely that there is some salinity in the water (a frequent feature of these reclaimed colliery sites in Yorkshire). The composite is from this later collection, the other three are from last year.

I am now happy that this is not Coronellaria pulicaris . . .

amitiés
Chris

Re : Coronellaria sp. on Schoenoplectus
That's wonderful, Chris?! This species is somewhat variable, but I would say that it has usually much less conspicuous hairs than typical C. pulicaris. C. pulicaris has also a different spore guttulation, see below.

Re : Coronellaria sp. on Schoenoplectus
No. I remember that the type of C. pulicaris needs to be restudied. It could well also be without croziers, or a mixture of the two species is possible. So a very difficile work to do.
