Hypholoma fasciculare

 



Hypholoma fasciculare, commonly known as the Sulphur tuft or clustered woodlover, is a common woodland mushroom, often in evidence when hardly any other mushrooms are to be found. This saprotrophic small gill fungus grows prolifically in large clumps on stumps, dead roots or rotting trunks of broadleaved trees.

The "sulphur tuft" is bitter and poisonous; consuming it can cause vomiting, diarrhea and convulsions. The principal toxin is a steroid known as fasciculol E.

The specific epithet is derived from the Latin fascicularis 'in bundles' or 'clustered', referring to its habit of growing in clumps. (Wikipedia)

Craterellus tubaeformis

Image
The yellowfoot is a small mushroom, usually only a few inches tall. Its common names give away its key distinguishing feature: the stem (the mushroom’s “foot”) is bright yellow, its stem is hollow (like a tube), it’s funnel or trumpet-shaped, and it’s brightly colored (like a flame). Yellowfoot mushrooms only grow from the ground or on decomposing logs; they never grow up trees or on solid logs. They grow in dense or scattered groupings across the forest floor, especially boggy, wet areas filled with lots of moss. The yellowfoot chanterelle is mycorrhizal (forms relationships with specific trees), with two species preferring conifers and one growing in association with hardwoods. (Mushroom Appreciation)
