Boletus pinophilus

Ciri dan struktur

The fruiting body has a convex-shaped cap, at first small in relation to its stipe, expanding in volume as it matures. The skin of the cap is dry, matte and can be coloured from maroon to chocolate brown with a reddish tint. It is thicker than other porcini-like boletes and is gelatinous. These characteristics distinguish it visually from relatives such as Boletus edulis, B. reticulatus and B. aereus. The young, immature cap may have a pale pink colour and a white, powdery flush. As with all boletes, the size of the fruiting body can vary greatly. The cap diameter can be as much as 40 cm, the stem height 25 cm and stem diameter 16 cm. The bulbous stipe is often swollen and has a network pattern, which is much coarser in this species than other porcinis. The overall colour may have an orange-red tinge which is more obvious in the lowest parts, although this is also common in other species. Like other boletes, B. pinophilus has small pores on the underside of its cap rather than gills. These are coloured white at first, becoming yellow with age and olive-brown at full maturity. The spores are cylindric-ellipsoid, smooth, with oil drops and dimensions 15.5–20 by 4.5–5.5 μm. They produce an olive-brown spore print.

Habitat dan peran ekologis

Boletus pinophilus adalah jamur yang paling langka di Eropa, meskipun ditemukan di wilayah berangin. Leningrad Oblast and Vologda Oblast in Rusia, dan Ukraina. Bolete dianggap rentan di Republik Ceko dan Irkutsk Oblast in Siberia. Hal ini juga ditemukan di perkebunan pinus eksotis (seperti Pinus sylvestris) di Amerika Utara timur, Meksiko, Chili, Selatan Africa and Selandia Baru. Native populations dari China and Utara America have sebagian besar dikonfirmasi sebagai spesies yang berbeda lainnya. B. pinophilus forms ectomycorrhizal relationships in symbiosis with pine (Pinus) species such as stone pine (P. cembra), black pine (P. nigra), Corsican pine (P. nigra subsp. laricio), cluster pine (P. pinaster), Monterey pine (P. radiata), Scots pine (P. sylvestris) and P. uncinata, as well as European silver fir (Abies alba) and European spruce (Picea abies). preferring the poor, acidic, and sandy soils associated with coniferous forests. Tampaknya lebih menyukai Pinus, sementara bentuk jamur yang terjadi dalam kombinasi dengan Abies and Picea has telah diberi label B. pinophilus var. fuscoruber. However, it is not confined to coniferous trees and may also be found fruiting in deciduous forests, such as under chestnut trees (Castanea sativa), oak (Quercus spp.), beech (Fagus sylvatica), and possibly birch (Betula spp.) and hornbeam (Carpinus spp.).
