Suillus
Encyclopedia
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
.
in 1821, in the first volume of his Natural Arrangement of British Plants. Setting Suillus luteus
as the type species
, he described the genus as those mushrooms with a centrally-placed stem, a distinct ring, a circular cap, and tubes that stuck together.
include the presence of a cylindrical stem
, cap
, soft flesh
and tubular hymenium
. Specific characteristics common to most species in Suillus are the cap cuticle
which is slimy and sticky when moist, as well as the strong mycorrhiza
l relationship developed with coniferous trees
. They have been commonly called "slippery jacks" because the cap of the fruiting body
is sometimes slimy. The genus name is derived from the Latin
sus, meaning "pig". Prior to 1997, the genus Suillus was considered part of the family Boletaceae
.
Intra-genus variation may be demonstrated by differences in colour and ornamentation of the cap cuticle, flesh, pores and stem, the presence of a partial veil
in immature forms and annuli
thereafter, pore shape and distribution, as well as habitat. The cap cuticle is dark brown in S. brevipes
, and yellow in S. grevillei
. S. granulatus
has a smooth cap cuticle, while that of S. lakei
is finely scaly. The pores are bright yellow in S. collinitus
, cinnamon in S. variegatus
and grey in S. viscidus
; in shape they are round in S. luteus
and angular in S. bovinus
. The flesh is white to yellow in S. luteus
, while it is pallid in S. variegatus
with a tendency to turn blue when exposed to air. Young S. luteus
and S. grevillei
bear partial veils whose remnants remain as annuli hanging from the stem; in S. granulatus
the stem is bare. S. viscidus
and S. grevillei
occur under larch
(Larix) only, while S. sibiricus
is restricted to a few species of pine
(Pinus).
Some Suillus species are edible
but none are highly esteemed. In some species, the slimy cap coat acts as a purgative when consumed and should be removed before cooking. Species of Suillus have been associated with the term "bolete
", given to members of other genera bearing pores, most notably Boletus
.
where members of the tree family Pinaceae
can be found. Although a few species are distributed in tropical regions (usually mountainous areas), most are limited to temperate
areas. Some species have been introduced
adventitiously with pine trees in pine plantation
s outside the natural area of Pinaceae.
Some Suillus species have entered regional red lists as endangered or vulnerable. Seven European countries have listed S. sibiricus
. Individual countries have also listed other species, including S. flavidus, S. tridentinus
, S. collinitus
, S. plorans and S. lakei
