Hebeloma gigaspermum is a European species of mushroom in the family Hymenogastraceae.
Taxonomy
[edit]The species Hebeloma gigaspermum was first described only in 1981[1] and is externally similar to the much better-known Hebeloma sacchariolens (being placed in subsection Sacchariolentia of the genus). It is not uncommon in Northern Europe and until 1981 examples were probably simply considered to be H. sacchariolens.[2]
The name gigaspermum means "giant-spored".
Description
[edit]It is a nondescript clay brown or ochre mushroom with somewhat viscid cap, up to about 5 centimetres (2 inches) in diameter, and has a strong sweet odour which has been likened to orange blossom or amyl acetate.[3]
Similar species
[edit]It is similar to H. sacchariolens, and according to one source can be distinguished by
- its ecology with willow and alder in boggy ground (as opposed to forests and gardens with broad-leaved trees in general), and
- its large spore size of 13–17 × 7–9 μm (as opposed to 11–14 × 6–8 μm).[2]
As Hebeloma contains poisonous species, H. sacchariolens is not to be recommended for culinary use.[citation needed]
