Ciri dan struktur

Like many other mushrooms, L. indigo develops from a nodule that forms within the underground mycelium, a mass of threadlike fungal cells called hyphae that make up the bulk of the organism. Under appropriate environmental conditions of temperature, humidity, and nutrient availability, the visible reproductive structures (fruit bodies) are formed. The cap of the fruit body, measuring between 4–15 cm in diameter, is initially convex and later develops a central depression; in age it becomes even more deeply depressed, becoming somewhat funnel-shaped as the edge of the cap lifts upward. The margin of the cap is rolled inwards when young, but unrolls and elevates as it matures. The cap surface is indigo blue when fresh, but fades to a paler grayish- or silvery-blue, sometimes with greenish splotches. It is often zonate: marked with concentric lines that form alternating pale and darker zones, and the cap may have dark blue spots, especially towards the edge. Young caps are sticky to the touch. Fruit bodies of L. indigo have no distinguishable odor. When viewed in mass, as in a spore print, the spores appear cream to yellow colored. Viewed with a light microscope, the spores are translucent (hyaline), elliptical to nearly spherical in shape, with amyloid warts, and have dimensions of 7–9 by 5.5–7.5 μm. Cystidia are terminal cells of hyphae in the hymenium which do not produce spores, and function in aiding spore dispersal, and maintaining favorable humidity around developing spores. The pleurocystidia are cystidia that are found on the face of a gill; they are 40–56 by 6.4–8 μm, roughly spindle-shaped, and have a constricted apex.

Habitat dan peran ekologis

Lactarius indigo tersebar di seluruh selatan dan timur Utara America but paling umum di sepanjang Pantai Teluk, Meksiko, dan Guatemala. Frekuensi penampilannya di Appalachian Mountains of the United States has digambarkan sebagai "sesekali sampai umum di daerah setempat". Ia juga ditemukan di Meksiko, Guatemala, Kosta Rika (di hutan yang didominasi oleh ek), dan sejauh selatan hutan awan Humboldt oak Kolombia. Di Eropa, sampai saat ini hanya ditemukan di Prancis selatan. It has also been collected from China and India. A study on the seasonal appearance of fruiting bodies in the subtropical forests of Xalapa, Mexico, found that maximal production of L. indigo coincided with the rainy season between June and September. Ini adalah jamur mikoriza, dan sebagai semacamnya, membangun hubungan mutualistik dengan akar pohon tertentu ("host"), di mana jamur pertukaran mineral dan asam amino yang diekstrak dari tanah untuk karbon tetap dari host. Di bawah tanah hifa jamur tumbuh lapisan jaringan di sekitar akar-akar dari berbagai spesies pohon, membentuk apa yang disebut ektomycorrhizae ⁇ sebuah hubungan intim yang sangat bermanfaat bagi inang, karena jamur menghasilkan enzim yang mengmineralkan senyawa organik dan memfasilitasi transfer nutrisi ke pohon.

Ringkasan sumber

Lactarius indigo, commonly known as the indigo milk cap, indigo milky, indigo lactarius, blue lactarius, or blue milk mushroom, is a species of agaric fungus in the family Russulaceae. The fruit body color ranges from dark blue in fresh specimens to pale blue-gray in older ones. The "milk", or latex, that oozes when the mushroom tissue is cut or broken (a feature common to all members of the genus Lactarius) is also indigo blue, but slowly turns green upon exposure to air. The cap has a diameter of 4–15 cm, and the stem is 2–8 cm tall and 1 – 2.5 cm thick.

Ekologi sumber

Lactarius indigo is distributed throughout southern and eastern North America but is most common along the Gulf Coast, Mexico, and Guatemala. Its frequency of appearance in the Appalachian Mountains of the United States has been described as "occasional to locally common". It is also found in Mexico, Guatemala, Costa Rica (in forests dominated by oak), and as far south as the Humboldt oak cloud forests of Colombia. In Europe, it has so far only been found in southern France. It has also been collected from China and India. A study on the seasonal appearance of fruiting bodies in the subtropical forests of Xalapa, Mexico, found that maximal production of L. indigo coincided with the rainy season between June and September. It is a mycorrhizal fungus, and as such, establishes a mutualistic relationship with the roots of certain trees ("hosts"), in which the fungi exchange minerals and amino acids extracted from the soil for fixed carbon from the host. The subterranean hyphae of the fungus grow a sheath of tissue around the rootlets of a broad range of tree species, forming so-called ectomycorrhizae—an intimate association that is especially beneficial to the host, as the fungus produces enzymes that mineralize organic compounds and facilitate the transfer of nutrients to the tree.
