Sulfur Tuft and ????

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:

am having a hard time with an ID of the Fungi growing at the top of the stump where it has splintered.
