01 / Morfologi

Ciri dan struktur

The fruit bodies of Boletopsis nothofagi usually grow in tufts and only rarely individually. They have a centrally stalked cap. The cap is convex, measuring 10 – 80 mm wide and 5 – 22 mm high. In young specimens, the cap's edge is slightly bent, whereas the cap of older fruit bodies often curl. The cap cuticle is gray in color, and its texture ranges from smooth to slightly fibrous. Pressure- or scrape-spots are stained darker and eventually blacken. The stipes are club-shaped to cylindrical, slightly tapering towards both base and cap, with a height of about 20 – 60 mm and a thickness of 10 – 25 mm. The stipe is smooth and dry on the surface and has a firm texture on the inside. The stipes have a similar color as the cap and shows the same responses to damage. The white, porous hymenium has a thickness of 1–2 mm and turns brown when bruised. Per millimeter, there are two to three square pores. When dried, the hymenium's color becomes pinkish-brown. The hymenium extends slightly down the stipe, and is sharply defined. Dried tissue smells similar to fenugreek. The morphology of the mycorrhiza has not yet been described; however, as with all other types of Boletopsis it is likely to be ectomycorrhizal. Boletopsis nothofagi has a monomitic hyphal structure, whereby all hyphae are generative hyphae, which serve the growth of the fungus. The cap, when viewed under a microscope, is clearly differentiated and consists of a cutis, a layer of oriented hyphae lying radially. They are up to 2 μm thick, pigmented brown and covered with small, irregularly shaped granules. They become green when stained with potassium hydroxide (KOH), a diagnostic characteristic of the genus.

Habitat dan peran ekologis

The known range of Boletopsis nothofagi is limited to two narrowly defined areas of New Zealand, one on the North Island and the other on the South Island. These areas are in Rimutaka Forest Park near Wellington, and Saint Arnaud in the northern part of the South Island. These locations are relatively far away from each other and isolated, which, together with its absence in the rest of New Zealand, makes it unlikely that the species is a recent import. It is more likely that the species is native to New Zealand and has been overlooked in earlier surveys due to its rarity. Boletopsis nothofagi is the most southern member of the genus Boletopsis, and as of 2013 the sole known member of the genus in the Southern Hemisphere; its closest relatives are found in Asia and Costa Rica. The occurrence of Boletopsis nothofagi seems to be strongly connected to the occurrence of the southern beech Nothofagus fusca, a species of Fagales that is endemic to New Zealand. B. nothofagi has been found exclusively in N. fusca forests spread through New Zealand below 37° S. The fungus forms a mycorrhizal association with the trees of N. fusca, in which the hyphae of the fungal mycelium wrap around the roots of the tree and penetrate the cortex, but not its cells.

They become green when stained with potassium hydroxide (KOH), a diagnostic characteristic of the genus. The subcutis consists of swollen hyphae up to 6 μm thick. These are thin-walled, filled with oil droplets and have clamp connections in the septa. The hymenial layer has porous cystidium structures measuring 4 by 80 μm. The basidia of B. nothofagi are pleurobasidia arising on the sides of the hyphae.

Ringkasan sumber

Boletopsis nothofagi is a fungus in the family Bankeraceae. The fungus forms grey fruit bodies that grow in clusters. Like all species of Boletopsis, it has a porous spore-bearing surface on the underside of the cap, but differs from other species of Boletopsis by having characteristics such as elongated spores and a green discoloration when stained with potassium hydroxide. Boletopsis nothofagi is endemic to New Zealand and has a mycorrhizal association with red beech (Nothofagus fusca). It is unknown when exactly the fungus forms its fruit body, but it has so far been found solely in May, during autumn in the Southern Hemisphere.
