Pulvinula johannis ?
Patrice TANCHAUD, 10-02-2013 23:40
Bonsoir,

Sur sol un peu sablonneux, plus ou moins parmi les mousses, au long d'une haie de Cupressus. Asques 155-195 µm. Spores (8,5)9,5-10(11) µm. J'arrive à Pulvinula johannis (cf. Sydowia 60(2): 248, 2008), mais ce qui me gêne c'est que je ne vois pas de spores uniguttulées. Merci d'avance pour vos avis éventuels.

On sandy ground a little among mosses, along a Cupressus hedge. Asci 155-195 µm. Spores (8,5)9,5-10(11) µm. I think it coult be Pulvinula johannis (cf. Sydowia 60 (2): 248, 2008), but there is a problem, I do not see spores with one guttule. Thank you in advance for your advice possible. (Sorry for bad english ...)
