Lactifluus rupestris

Ciri dan struktur

The cap of L. rupestris is 60 – 70 mm, concave to somewhat funnel-shaped, with a central depression. Its color is orange at the center to brownish-orange towards the margin. The cap surface is somewhat sticky, and the texture is either smooth to slightly cracked. It has an indistinct layer of matted mycelial "hairs". The margin lacks striations and grooves, and is curled inward slightly. The gills are slightly decurrent (running slightly down the length of the stem), cream-salmon in color, and crowded closely together. They are up to 3 mm broad and are frequently branched. The gill edges are smooth, and the same color as the gill face. There are several tiers of lamellulae (short gills that do not extend fully from the cap margin to the stem) interspersed between the gills. The stem is 35 – 45 mm long by 18 – 21 mm thick, centrally attached to the stem, cylindrical, and tapers slightly near the base. It is pale ochraceous-salmon, and slight longitudinal ribs can be seen with a magnifying glass. The flesh is spongy, pale yellow-ochre in the cap, and cream-yellow in the stem. The latex is cream-colored to roughly the same color as the gills, and not abundant. The spores are roughly ellipsoid to roughly spherical, and typically measure 7–8.5 by 6–7 μm. The ornamentation on the spore surface is amyloid (staining blue to blue-black in Melzer's reagent) and finely wart-like, with each wart ranging to 0.5–0.7 μm high. The warts are interconnected by thin ridges, but the ridges do not form a complete reticulum. The hilar appendage (the part of a spore once attached to the basidium via the sterigma) ranges in shape from narrowly obtuse to somewhat conical; the plage is not very distinct, but has an amyloid spot.

Habitat dan peran ekologis

Jamur ditemukan terkubur dengan hingga dua pertiga batangnya di tanah berpasir di dekat beberapa semak (Fabaceae, subfamili Mimosoideae and lainnya) di daerah semi kering, setelah hujan deras. Spesies ini hanya dikenal dari lokasinya tipe di Vale do Catimbau National Park in Brasil, di negara bagian Pernambuco. Buah-buahan ini berupa bunga yang berketinggian 900 sampai 1000 m. Ini adalah bagian dari ekosistem cerrado bermacam-macam, di daerah yang dikenal sebagai campos rupestres. Although the fungus is suspected to be mycorrhizal (like all Lactarius), there was a wide diversity of plant species growing in the open, dry forest where the mushroom was found (including members of the tree families Euphorbiaceae, Fabaceae, Myrtaceae, Nyctaginaceae, and Polygonaceae—all known to form mycorrhizal associations), so the authors did not speculate on any specific interactions.

Reproduksi

The spores are roughly ellipsoid to roughly spherical, and typically measure 7–8.5 by 6–7 μm. The ornamentation on the spore surface is amyloid (staining blue to blue-black in Melzer's reagent) and finely wart-like, with each wart ranging to 0.5–0.7 μm high. The warts are interconnected by thin ridges, but the ridges do not form a complete reticulum. The hilar appendage (the part of a spore once attached to the basidium via the sterigma) ranges in shape from narrowly obtuse to somewhat conical; the plage is not very distinct, but has an amyloid spot. The basidia (spore-bearing cells in the hymenium) are 35–50 by 8–11 μm, club-shaped, and bear mainly four, but sometimes two long (6–10 μm) sterigmata.
