Cistella ? on Schoenoplectus tabernaemontani

Chris YeatesBonjour tous
recently collected on dead stems of this plant; it appears to be a Cistella, but I can't get it to fit any of the species given for this genus on monocots in Raitviir. Perhaps I am missing something . . . .
Hairs with short verrucose projections, more or less parallel-sided, occasionally slightly swollen at apex (3.2-4.5µm at apex).
Asci 45-53 x 5.5-7µm. With croziers, IKI +
Ascospores 12.6-16.4 x 2.8-3.2µm.
Cordialement
Chris

Hi Chris

Cistella albidolutea would have such spores  but I know it with wider hair tips. Because of which features did you miss this in Raitviir's key?

Zotto

P.S. I just noted that I have a different folder for collections with larger LBs in the spores, see Cubby (renamed to albidolutea, large LBs).

Hi Zotto
not sure what you mean by "see Cubby" . . . . .
In Raitviir I get to this couplet:
28.  Hairs apically 5-11µm wide                                           C. albidolutea
28'. Hairs apically up to 4µm wide                                        C. tuvensis

the hairs in my collection sit inconveniently between the two ;-); that plus the fact that for albidolutea he talks of "small polar lipid guttules" which again does not fit here.
regards
Chris

Re : Cistella ? on Schoenoplectus tabernaemontani
C. tuvensis in Raitviir is badly described. It has rather long hairs and too narrow spores (no mention of guttulation). On Raitviir's sketch the spores are only about 1-2 µm wide, although he says 2-2.2 µm.
