Ciri dan struktur

The cap of B. ananas is 3.3-10 cm wide and 6-14 mm wide, and gradually becomes larger towards the base to 10–19 mm. The top part of the stem is cream to pink, the middle finely longitudinally striate, with the striations darkening with handling, red-lavender to brown-red, lighter with age. Immediately above the basal tomentum the stem surface is cream-colored with few striations. The basal tomentum is made of stiff, coarse white hairs over the lower 6–50 mm. The flesh of the stem is solid (i.e., not hollow) white to buff-tan to light yellow, and turns slightly blue with exposure. The odor is not distinctive (although it has been described as "musty") and the taste is mild. The spores are olivaceous-brown in medium to heavy deposit. They are inamyloid, almond-shaped, contain one or more oil droplets, and measure 17.5–22.2 by 6.4–8 μm. The spore wall is 0.5–1 μm thick, with 12–14 longitudinal ridges. These ridges are less than 1 μm tall, occasionally bifurcating, converging at poles, with minute cross-striae. Although these cross-striae are visible when observed with light microscopy, they are not evident when viewed with scanning electron microscopy. The hilar appendage (the region of a spore which attaches to the basidium via the sterigma) is 0.3–1 μm long. The basidia are four-spored, club-shaped, and have numerous refractive globules; they measure 39–57 by 11–15 μm. The pleurocystidia (cystidia on the face of a gill) are 42–47 by 8-12 μm, swollen and beaked, slightly capitate. They are abundant, arising from the subhymenium, projecting 19.3–29.6 μm above the hymenial palisade, thin-walled, hyaline, and devoid of refractive contents.

Habitat dan peran ekologis

The fruit bodies of B. ananas typically grow scattered or in groups under oak and pine trees, often on their bases. Di Guyana, jamur biasanya menghasilkan buah secara tunggal atau berpasangan di dalam 1-2 m di atas permukaan tanah di batang pohon tropis Dicymbe corymbosa (subfamilia Caesalpinioideae), yang terkait dengan ektomikorris dalam akumulasi humik. Jarang ditemukan berbuah di tanah pada kayu yang sangat rusak, akarnya menembus. Rolf Singer suggested bahwa jamur itu tidak mikoriza, mencatat bahwa selain terjadi di bawah atau di dasar pohon pinus dan ek, itu terjadi dalam humus yang sedikit dan puing-puing yang terakumulasi di dinding batu. Singer concluded bahwa spesies lebih memilih untuk tumbuh di permukaan keras. Harry D. Thiers, dalam studi tentang flora bolete Texas, menulis bahwa B. ananas adalah spesies langka yang sering berbuah banyak setelah periode hujan yang panjang dan kelembaban tinggi. Some varieties dari B. ananas dari Amerika Utara tenggara, Kosta Rika, Brasil, Panama, Nikaragua, dan Guyana have telah dicatat untuk buah di batang pohon, meskipun buah darat telah dilaporkan di Malaysia and Amerika Tengah. Due to kebiasaan berbuah yang biasanya tinggi dan kejadian pada kayu mati, status ektomikoriza B. ananas telah diperdebatkan; dalam protolog Murrill noted "itu selalu terjadi baik sebagai parasit luka pada batang pinus atau di sekitar dasar pohon pinus hidup".

Ringkasan sumber

Boletellus ananas, commonly known as the pineapple bolete, is a mushroom in the family Boletaceae, and the type species of the genus Boletellus. Previously known as Boletus ananas and Boletus coccinea (among other synonyms), the species was given its current name by William Alphonso Murrill in 1909. The fruit body is characterized by the reddish-pink (or pinkish-tan to yellowish if an older specimen) scales on the cap that are often found hanging from the edge. The pore surface on the underside of the cap is made of irregular or angular pores up to 2 mm wide that bruise a blue color.

Ekologi sumber

The fruit bodies of B. ananas typically grow scattered or in groups under oak and pine trees, often on their bases. In Guyana, the mushroom typically fruits singly or in pairs within 1-2 m above ground level on the trunks of the tropical tree Dicymbe corymbosa (subfamily Caesalpinioideae), associated with ectomycorrhizas within humic accumulations. It is rarely found fruiting on the ground on heavily decayed, root-penetrated wood. Rolf Singer suggested that the fungus was not mycorrhizal, noting that as well as occurring under or on the bases of both pine and oaks, it occurred in scanty humus and debris accumulated on rock walls. Singer concluded that the species prefers to grow on hard surfaces. Harry D. Thiers, in his study of the bolete flora of Texas, wrote that B. ananas was a rare species that often fruited abundantly following an extended period of rain and high humidity. Some varieties of B. ananas from southeastern North America, Costa Rica, Brazil, Panama, Nicaragua, and Guyana have been noted to fruit on tree trunks, although terrestrial fruiting has been reported in Malaysia and Central America. Due to the typically elevated fruiting habit and occurrence on dead wood, the ectomycorrhizal status of B. ananas has been debated; in the protolog Murrill noted "it always occurs either as a wound parasite on pine trunks or about the base of living pine trees".
