Sulfur Tuft
Hypholoma fasciculare

Field Notes
Description:
The hemispherical cap can reach 6 cm (2⅓ in) diameter. It is smooth and sulphur yellow with an orange-brown centre and whitish margin. The crowded gills are initially yellow but darken to a distinctive green colour as the blackish spores develop on the yellow flesh. It has a purple brown spore print.[3] The stipe is up to 10 cm (4 in) tall and 1 cm (⅓ in) wide, light yellow, orange-brown below, often with an indistinct ring zone coloured dark by the spores. The taste is very bitter, though not bitter when cooked, but still poisonous.
Habitat:
Hypholoma fasciculare grows prolifically on the dead wood of both deciduous and coniferous trees. It is more commonly found on decaying deciduous wood due to the lower lignin content of this wood relative to coniferous wood. Hypholoma fasciculare is widespread and abundant in northern Europe and North America. It has been recorded from Iran,[4] and also eastern Anatolia in Turkey.[5] It can appear anytime from spring to autumn.[3
Notes:
Symptoms may be delayed for 5–10 hours after consumption, after which time there may be diarrhea, nausea, vomiting, proteinuria and collapse. Paralysis and impaired vision have been recorded. Symptoms generally resolve over a few days. The autopsy of one fatality revealed fulminant hepatitis reminiscent of amatoxin poisoning, along with involvement of kidneys and myocardium. The mushroom was consumed in a dish with other species so the death cannot be attributed to sulfur tuft with certainty.[
