Suillus viscidus
Encyclopedia
Suillus viscidus is an edible, uncommon mushroom
in the genus Suillus
. It associates with larch
and is found throughout Europe and in Japan.
is hemispherical when young, later convex to flat, whitish grey or darker. It is up to 12 cm in diameter. It is slimy, and blotchy when old. The large, angular pores
on the underside of the cap are coloured pallid to yellowish at first, but become darker with maturity. Yound specimens bear a whitish partial veil
which soon shreds. The tubes
are concolorous, and have a slightly decurrent stem attachment. The stem
bears a thin, slimy, dark-coloured ring
in the uppermost part of the stem which is sometimes lost in mature specimens. The stem is divided by the ring into a short lighter, yellowish section above, and a duller, greyish section below. The flesh is whitish-grey, very soft and has a mild or non-distinct taste.

(Larix) specifically, and its distribution is thus limited by the range of the host tree. It occurs throughout Europe, and also in Japan. In Europe, it is considered an uncommon to rare fungus and it is to be found in the same habitat as the common larch bolete, Suillus grevillei
, and also the rare Suillus tridentinus
. Fruiting bodies are found in groups among grass under larch, from summer to autumn.
Mushroom
A mushroom is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus; hence the word "mushroom" is most often applied to those fungi that...

Suillus
Suillus is a genus of basidiomycete fungi in the family Suillaceae and order Boletales. Species in the genus are associated with coniferous trees, and are mostly distributed in northern temperate locations, although some species have been introduced to the Southern Hemisphere.-Taxonomy:The genus...

The capPileus (mycology)
The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp that supports a spore-bearing surface, the hymenium. The hymenium may consist of lamellae, tubes, or teeth, on the underside of the pileus...

Hymenium
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia or...

Annulus (mycology)
An annulus is the ring like structure sometimes found on the stipe of some species of mushrooms. The annulus represents the remaining part of the partial veil, after it has ruptured to expose the gills or other spore-producing surface. An annulus may be thick and membranous, or it may be cobweb-like...

In biology, a spore is a reproductive structure that is adapted for dispersal and surviving for extended periods of time in unfavorable conditions. Spores form part of the life cycles of many bacteria, plants, algae, fungi and some protozoa. According to scientist Dr...
