Hypholoma fasciculare, also known as Naematoloma
fasciculare, the Green-gilled Woodlover, or Sulfur Tuft can apparently
be eaten in North America, though it is generally bitter. It is mistaken
for both the edible Hypholoma capnoides and for Honey Mushrooms
in the Armillaria mellea group. In Europe and in Japan there have
been severe poisonings and possibly even a death from Hypholoma fasciculare.
The latent period is 5 to 10 hours with onset of symptoms marked
by nausea, vomiting, diarrhea, and possible collapse. Impaired vision and
paralysis have been reported. As in many mushroom poisonings, the one death
involved a mixed ingestion of more than one toxic species. Figuring out
the cause of a poisoning is often confounded when individuals eat many
species at once or accidentally mix a few toxic species in with otherwise
edible species. The problem is compounded when no whole mushrooms are set
aside and saved. Identifying a potential problem is also difficult when
young children are grazing in the yard and you cannot be certain of what
they ate.
