Ciri dan struktur

The caps of the fruit bodies are up to 15 cm in diameter, red or brownish-red in color, initially convex but flattening out as they develop. The flesh is firm but watery, thick, and either not changing color or becoming deeper yellow with bruising. usually thickest at the base and tapering upward, up to 4 cm thick below and 0.5 to 1 cm at the apex. It typically starts out with a bulbous shape but becomes more equal in width throughout as it matures. The surface is dry, often roughened and pitted, and with a network of grooves or ridges (striations) or reticulations near the top of the stem. It is about the same color as the cap, but will bruise to a darker reddish-brown near the base. The stem is solid (that is, not hollow), and its flesh pale purplish at the top, but yellowish below. Mycelium at the base of the stem is also yellow. Collected in deposit, the spores are olive-brown. Viewed with a microscope, the spores are spindle-shaped to roughly elliptical, with smooth, thick walls, and have dimensions of 18–22 by 7–9 μm. Overholts' 1940 publication on the species reported spore dimensions of 20–26 by 8–9 μm. The basidia (spore-bearing cells) are club-shaped, hyaline (translucent), 4-spored, and 31–36 by 7–11 μm. Cystidia (sterile cells on the face of a gill) are thin-walled, and measure 60–90 by 10–18 μm. There are no clamp connections present in the hyphae.

Habitat dan peran ekologis

The fruit bodies grow solitarily, scattered, or sometimes in small groups on the ground or on well-decayed conifer logs, especially of western and mountain hemlock, but occasionally also Douglas-fir and western red cedar. Jamur ini sangat diduga membentuk hubungan mikoriza dengan hemlock, meskipun upaya standar untuk menumbuhkan B. mirabilis mikorisa dalam budaya laboratorium telah gagal. Although fruit bodies are sometimes found growing on logs with advanced brown cubical rot—a trait suggestive of cellulose-decomposing saprobic fungi—the rotten wood harboring the fungi typically contains abundant conifer roots. Hal ini telah disarankan bahwa B. mirabilis telah secara khusus beradaptasi dengan ceruk ini untuk mengurangi persaingan nutrisi dengan jamur mikoriza lainnya, dan lebih lanjut, bahwa ketidakmampuan untuk menanam mikorrizae di laboratorium menggunakan teknik standar mungkin karena karakteristik fisik atau kimia tertentu dari kayu dengan kutub cokelat diperlukan untuk pertumbuhan jamur. Aureoboletus mirabilis, yang biasanya muncul dari akhir musim panas hingga musim gugur, didistribusikan di hutan hemlock Pantai Pasifik Ranges from Utara California to Alaska, Cascade Range, serta di hutan pedalaman seperti di Manitoba.

Ringkasan sumber

Aureoboletus mirabilis, commonly known as the admirable bolete, the bragger's bolete, and the velvet top, is a species of fungus in the Boletaceae mushroom family. The fruit body has a dark reddish-brown cap, yellow to greenish-yellow pores on the undersurface of the cap, and a reddish-brown stem with long narrow reticulations. Aureoboletus mirabilis is found in coniferous forests along the Pacific Coast of North America, and in Asia. Unusual for boletes, A. mirabilis sometimes appears to fruit on the wood or woody debris of Hemlock trees, suggesting a saprobic lifestyle.

Ekologi sumber

The fruit bodies grow solitarily, scattered, or sometimes in small groups on the ground or on well-decayed conifer logs, especially of western and mountain hemlock, but occasionally also Douglas-fir and western red cedar. The fungus is strongly suspected to form mycorrhizal associations with hemlock, although standard attempts at growing B. mirabilis mycorrhizae in laboratory culture have failed. Although fruit bodies are sometimes found growing on logs with advanced brown cubical rot—a trait suggestive of cellulose-decomposing saprobic fungi—the rotten wood harboring the fungi typically contains abundant conifer roots. It has been suggested that B. mirabilis has specifically adapted to this niche to reduce competition for nutrients with other mycorrhizal fungi, and further, that the inability to culture mycorrhizae in the lab using standard techniques may be because certain physical or chemical characteristics of the wood with brown cubical rot are required for fungal growth. Aureoboletus mirabilis, which usually appears from late summer to autumn, is distributed in the hemlock forests of the Pacific Coast Ranges from Northern California to Alaska, the Cascade Range, as well as in interior forests such as in Manitoba.
