Ciri dan struktur

The cap of the fruit body is 3 to 12 cm in diameter, and depending on its age, is either conic to convex, to somewhat flattened at maturity. The cap margin is initially rolled downward before straightening out, often with hanging remnants of partial veil (appendiculate). The cap surface is covered with densely matted filaments that are rough and scale-like. The scales are pink to brownish red, fading to a pale brown-gray or dull yellow in maturity. Under the scales, the cap surface is yellow to pale yellow-orange. While many other Suillus species have a sticky or slimy cap, S. spraguei is dry. The flesh is yellow. The pores on the underside of the cap are yellowish and angular, measuring 0.5 to 5 mm wide, and formed by tubes that extend 4 to 8 mm deep. These pores have a slightly decurrent attachment to the stem (extending down its length). Young specimens have a whitish fibrous partial veil that protects the developing pores; as the cap expands it rips the veil, which remains as a grayish ring on the stem. The stem is 4 to 12 cm long, and 1 to 2.5 cm thick, roughly cylindrical in shape, or sometimes with a bulbous bottom so as to be somewhat club-shaped. The stem surface is tomentose, with scales at the top, and a ring on the upper half of the stem. Below the ring the stem is fibrillose, covered with a mat of soft hairs. Its color at the top is yellow, but with wine-red to reddish-brown scales below, underlaid with a pale yellow to grayish color. The stem is usually solid, rarely hollow. The tissue of all parts of the fruit body—cap, pores, and stem—will turn brownish shortly after being bruised or injured.

Habitat dan peran ekologis

Dalam alam, S. spraguei membentuk hubungan ektomikoriza dengan spesies pinus lima jarum. tetapi mereka dapat ditemukan selambat pada bulan Oktober. Jamur dapat menjadi parasit oleh jamur Hypomyces completus. Pada tahap asexual H. completus, awalnya muncul sebagai bintik-bintik jamur putih pada permukaan topi atau batang yang dengan cepat menyebar untuk menutupi seluruh permukaan jamur dan menghasilkan konidia (spora asexual). Pada tahap seksual, jamur berubah warna, berkembang dari kuning-kecoklatan ke coklat, hijau-kecoklatan dan akhirnya hitam saat membuat perithecia, askus yang mengandung struktur seksual yang menghasilkan askospora. Peritesi adalah jerawat dan memberikan permukaan tekstur kasar. Sebuah studi Japanese field menemukan bahwa S. spraguei adalah jamur dominan dalam kondisi 21 tahun Korean pine, baik dalam hal ektomikoriza (diukur sebagai persentase biomassa yang ada dalam sampel tanah) dan produksi tubuh buah (yang terdiri dari 90% dari berat kering total tubuh buah yang dikumpulkan dari semua spesies). Produksi S. spraguei buah tubuh rata-rata sekitar satu per meter persegi, tanpa banyak variasi selama periode penelitian empat tahun. Jamur muncul sebagian besar dari August to November, cenderung tumbuh dalam kelompok, dan distribusi spasial kelompok secara acak ⁇ lokasi kelompok tidak berkorelasi dengan penampilan di tahun sebelumnya.

Reproduksi

In deposit, such as with a spore print, the spores of S. spraguei appear olive-brown in color; this changes to clay or tawny-olive after drying. Microscopically, the spores have smooth surfaces, measuring 9–11 by 3–4.5 μm; in side profile they have asymmetrical sides and a suprahilar depression (a surface indentation formed where the spore attaches to the basidia), while in face view they appear oblong. The spores are not amyloid, meaning that they do not absorb iodine when stained with Melzer's reagent. The basidia (the spore-bearing cells in the hymenium) are thin-walled, four-spored, and have dimensions of 17–19 by 5–7.8 μm. In the presence of potassium hydroxide, they appear hyaline (translucent), and they become pale yellow to nearly hyaline in Melzer's reagent.

Ringkasan sumber

Suillus spraguei is a species of fungus in the family Suillaceae. It is known by a variety of common names, including the painted slipperycap, the painted suillus or the red and yellow suillus. Suillus spraguei has had a complex taxonomical history and is also frequently referred to as Suillus pictus. The readily identifiable fruit bodies have caps that are dark red when fresh, dry to the touch, and covered with mats of hairs and scales that are separated by yellow cracks. On the underside of the cap are small, yellow, angular pores that become brownish as the mushroom ages.

Ekologi sumber

In nature, S. spraguei forms ectomycorrhizal relationships with five-needled pine species. but they may be found as late as October. The mushrooms can be parasitized by the fungus Hypomyces completus. In the asexual stage of H. completus, it appears initially as patches of whitish mold on the surface of the cap or stem that rapidly spread to cover the entire mushroom surface and produce conidia (asexual spores). In the sexual stage, the mold changes color, progressing from yellow-brown to brown, greenish-brown and eventually black as it makes perithecia, asci-containing sexual structures that produce ascospores. The perithecia are pimply and give the surface a roughened texture. A Japanese field study found that S. spraguei was the dominant fungus in a 21-year-old stand of Korean pine, both in terms of ectomycorrhizae (measured as percentage of biomass present in soil samples) and by fruit body production (comprising over 90% of dry weight of total fruit bodies collected of all species). The production of S. spraguei fruit bodies averaged about one per square meter, without much variance during the four-year study period. The mushrooms appeared mostly from August to November, tended to grow in clumps, and the spatial distribution of clumps was random—the location of the clumps was not correlatable with appearances in previous years.
