I agree that this is probably an undescribed sp.

my problem lies with the fact that only guessed at named obsies from here on MO are being used to support your current name.

I await a published description that includes the pale (white or yellow) margin.

otherwise, we really can’t call this sensu anything; it is unique.

other collections on MO of Hygrocybe hypohaemacta sensu auct. Neotrop. exhibit a similar light colored margin. Here is a photo from the Jawaharlal Nehru Tropical Botanic Garden and Research Institute, India. http://www.jntbgri.in/...

Myxomop provides this citation and information: “Pileus and stipe very slimy, pileus scarlet with narrow yellow margin.” http://mushroomobserver.org/observer/show_observation/63264

white margin to cap is unusual and undescribed for hypohaemacta.

I cannot find it described anywhere. Here is the sp. description from one of Jean Lodge’s papers:

“Hygrocybe hypohaemacta is characterized by the glutinous pileus and stipe, scarlet pileus, white, free lamellae and dimorphic basidia and spores with globose or subglobose macrospores. It was originally described from Singapore (Corner, 1936) and has been reported in the neotropics from Puerto Rico (Lodge and Pegler, 1990), Jamaica and the US Virgin Islands (Cantrell and Lodge, 2001) in the Greater Antilles, Martinique in the Lesser Antilles (Pegler and Fiard, 1978; Pegler 1983), and Colombia (Franco-Molano and Uribe- Calle, 2000), French Guyana (Courtecuisse, 1989) and Venezuela (Dennis, 1961) in northern South America.”


The white margin is a pretty in your face character. Surely finders of this mushroom would have described it??!
