Bonjour Neocoyote,
Comme toi depuis le début des discussion,je penche vers Conocybe tenera; maintenant c' est vrai que pour avoir une certitude avec ce genre, un examen microscopique s' avère nécessaire.
Bon W.E.

bonjour a tous moi je penche sur B. lacteus jean-louis

Salut Jean-Louis,

Bolbitius lacteus is a little-known species and subject of both taxonomic and nomenclatural
confusion. After its introduction by Lange (1940) it was not redescribed until
Watling & Knudsen (1981) and Watling (1983), based on a single collection from
Denmark. Watling claimed that his material agrees with the original diagnosis in
every way, but in fact it differs considerably in spore size (Watling 8.5-10.0(-11.0) x
5.0-6.0(-6.5) µm; Lange 10.5-11.5 x 6.0-6.3 µm). Moreover the collection was not
made in grassland, as Lange did, but in a shady place under Sambucus nigra. In my
opinion B.lacteus sensu Watling is identical with B. reticulatus var. pluteoides. Several
Dutch collections, labelled as Bolbitius lacteus, appeared also to belong to B. reticulatus
var. pluteoides. The two taxa can be easily separated by differences in spore size and
colour and thickness of the spore wall, and usually also by habitat. B. reticulatus var.
pluteoides occurs in forests, usually on decayed wood but sometimes on soil, whereas
B. lacteus grows on dead grass remains or soil in meadows and roadside verges.
In nomenclatural respect Bolbitius lacteus has been confused with Conocybe apala
(Fr.: Fr.) Arnolds, until recently better known as C. lactea J.E. Lange. C.apala is placed
by sorne authors in the genus Bolbitius, for instance by Bon in (1992). The plate of
B. lacteus in Bon (1987) erroneously represents Conocybe apala, readily recognized
by the elongated, campanulate pileus and microscopically by the lecythifonn cheilocystidia.

Ok, merci Gigi.
Courtec. & Lécuru le reprennent en tant que variété de Bolbitius tener, soit Bolbitius tener var. lacteus (J.E. Lange M. Bon (1990).
Une "rareté"…Recensé une seule fois dans le Nord de la France (Le Romelaëre 06.10.2004).
Bonne journée.
