Suillus grevillei, commonly known as tamarack jack,[3] Greville's bolete, or larch bolete, is a mycorrhizal mushroom with a tight, brilliantly coloured cap, shiny and wet looking with its mucous slime layer. The hymenium easily separates from the flesh of the cap, with a central stalk that is quite slender. The species has a ring or a tight-fitting annular zone.
Etymology
[edit]The specific epithet is derived from Robert Kaye Greville.[4]
Description
[edit]Suillus grevillei is a mushroom with a 5–10 cm (2–4 in) cap colored from citrus yellow to burnt orange,[5] that is at first hemispherical, then bell-shaped, and finally flattened. It has a sticky skin, often with veil remnants on the edge,[6] short tubes of yellow (possibly staining brownish)[6] which descend down to the bottom of its cylindrical stalk (6–10 x 1–2 cm), which is yellowish above the ring area with streaks of reddish brown below.[6] The flesh is yellow, staining brown.[6]
The thin meat has consistency at first but then quickly becomes soft. It has an odor reminiscent of rumpled Pelargonium geranium leaves.[citation needed]
Habitat and distribution
[edit]It grows only under larch trees.[3] Widespread in North America and Europe (July–November).[5] In Asia, it has been recorded from Taiwan.[7]
Edibility
[edit]Suillus grevillei can be cooked as an edible mushroom, though one without culinary interest, if the slimy cuticle is removed from the cap.[8][5]
Chemistry
[edit]The fungus produces grevillin which is characteristic of this fungus. The genetic and enzymatic basis for atromentin, the precursor to various pulvinic acid-type pigments, has been characterized (an atromentin synthetase by the name, GreA). A cosmid library (31 249 bp in total) has been made from the genome. The estimated gene density based on the cosmid library is 1 per 3900 bp of genomic DNA. The genome has a GC content of 49.8%.[citation needed]
