The entire run of Mycotaxon is now available throu
salut a tous,on dead stem of indet. herbaceous plant we found in a poor meadow on calcarous ground these beautiful reddening helotiales. apothezia up to 1mm, with a conspicious darkening base, young apos are more or less dirty white.
spores quite variable in lenght and shape (19-26 x 4,5-7) with rounded ends, never pointed, vital with two bigger oil-drops ans some little ones, when overmature with a central septation. paraphyses filiform, a little swollen at the apex, sometimes with brownish drops at the tip, colouring red with lugol.
this all resembles much what is documentated in the zotto database under
https://drive.google.com/drive/folders/0B5SeyOEkxxZha002c3U5eklxOEU
but the problem is: the iodine-reaction in lugol is immediately blue and not red! who knows advice or has found this species too?

thank you very much! i will check iodine reaction and apical ring again. other microscopy has stunning similarity to collection i linked, in my view also the apos of the first two field-pictures. meanwhile i found a paper by ruben and you dealing with the species! there, a blue reaction is mentioned in weak iki-concentration, and a red one in strong concentration! so i will try again, drowning it in lugol and see if i can get a red one ;-)

the measuring of asci is 110-120 x 9-10. so unfortunately, much shorter than in the subliciformis-paper.
iodine-reaction seems to be "calycina-type". but stays blue! now i also saw in lugol coloring and VBs in the textura! same kind as in a. subliciformis.
perhaps a related species? maybe ... i will put it in the ?-folder ;-)

But Allophylaria is correct. A. byssacea would better fit, but that is red at any concentration! I only know A. macrospora on woody substrates which reacts blue (BB), but that has multiguttulate spores.
