lacks comprehensive information on tropical fungi. You will not find much information on your area’s fungi online, nor in books covering fungi Europe or North America.

Mycena is not exclusively conical. Many species have other cap shapes (eg: Mycena interrupta).

This may be more identifiable (though likely only to genus) with a look at more fruiting bodies at different stages of development.

Thanks, Alain.

Do you remember if the gills are pleated, like a skirt?

While Mycena can be planar in old age, usually it is conical. If this is young as you state, this could be a Marasmius or Marasmiellus, depending on actual size. Larger size, Marasmius; smaller Marasmiellus.

Arora says of M. maculata: “Cap 1.5-5 cm broad, conical to bell-shaped expanding to broadly convex or plane with a broad umbo, the margin sometimes uplifted in age; surface smooth, blackish-brown soon fading to brown or brownish-gray, but usually spotted with reddish-brown and sometimes entirely watery gray; striage when moist. Flesh thin, firm, grayish, slowly bruising reddish-brown.” This specimen appears more planar the conical, and does not have an umbo. According to Alexander Smith, author of a monograph on the genus, it is usually found on conifers. I don’t think this wood is coniferous.

Could be, according to Arora’s key to Agarics, either Hygrophoraceae or Tricholomataceae.

Do you remember any odor?

No “spotted”, but……

See, en.wikipedia.org/wiki/Mycena_maculata, it is said: " stain reddish, occasionally these stains do not appear, making it virtually indistinguishable from M. galericulata." This obsrvation in during tree day raining,no sun,it is a young spécimen with broken-stem,the wood dont touch the ground, etc…
For me the hat is as a plate, stem white and not reddish, realy fragilis…
I préfer M MACULATA, I add also M GALERICULATA. And sorry but usualy I speak french.

means “spotted”. How is this “spotted”, Alain?

You are very welcome.

My expertise on Tahiti fungi is badly lacking, though.

Thank you Daniel…..
