Hortiboletus rubellus

Ciri dan struktur

Basidiomes pileate-stipitate, xerocomoid, epigeal, small to medium-small sized. Ontogenetic development gymnocarpic. Pileus (2–)3.5–10(–15) cm broad, nearly hemispherical at first, then convex, pulvinate to applanate, also slightly depressed at centre, sometimes irregularly shaped; surface matt, dry, ± finely tomentose to sometimes rugulose, but later smooth, sometimes areolate towards the peripheral zone or with minute to coarse cracks especially in dry weather and showing a yellowish or somewhat pinkish subcuticular layer resembling some areolate Xerocomellus species; margin initially involute then extended, regular to wavy-lobed, acute and slightly exceeding the pileal context; rather variable in colours, but generally with bright red tints, initially blood red, wine red, cherry red, rose red, orange-red, pink, fading in mature basidiomes from ochraceous red, ochraceous pink to reddish-brown, with a margin at the very beginning whitish (due to a narrow band 1–2 mm broad), then gradually concolourous with age, unchanging or becoming slightly darker on handling or when injured. Tubes up to 12 mm long, at first adnate, later emarginate or slightly decurrent with a tooth, initially lemon or chrome yellow, later greenish-yellow to olive brown, slightly bluing when injured. Pores large, wider than 1 mm (up to 1.5–2 mm) in old basidiomes, roundish to angular, concolourous with the tubes, in mature basidiomes with orange-rusty tinges, weakly bluing when bruised and later becoming dirty brownish. Stipe (2–)2.5–7(–12) × 0.4–2.5(–3.5) cm, usually as long as or slightly longer than pileus diameter, central or slightly off-centre, solid, firstly versiform, clavate or somewhat bulbous, later more cylindrical or sometime inflated in the lower part, always tapering at the very base and slightly rooting; surface with fine reddish punctuations or fibrils on an ochraceous yellow background, later often with rather coarse longitudinal striations; surface usually concolourous with the pileus or paler, but yellow or pale yellow at apex; sometimes the stipe can be entirely yellow or entirely red, or a mix of both colours; basal mycelium whitish-yellow.

Habitat dan peran ekologis

Solitary, gregarious in small groups (2–3 basidiomes) or even subcaespitose, growing on bare soil, on litter or in the grass, often in anthropogenic environments, such as gardens, urban parks, lawns, meadows, disturbed roadsides, light grassy forest and planting edges, shrublands, sometimes in undisturbed forests, mostly under broadleaved trees including preferably Quercus spp. (Q. cerris, Q. coccifera, Q. faginea, Q. frainetto, Q. petraea, Q. pubescens, Q. pyrenaica, Q. robur), Castanea sativa, Fagus spp. (F. sylvatica, F. orientalis), and Tilia spp. (T. cordata, T. × europaea). Hal ini juga dikumpulkan di hutan campuran dengan kehadiran Carpinus betulus, Corylus avellana, Betula pendula, dan kadang-kadang Pinus sylvestris dan Salix spp, tetapi tidak ada laporan di hutan monodominant yang terdiri dari spesies ini. There are some molecularly unconfirmed data (Engel et al. 1996; Ladurner and Simonini 2003; Assyov in litt.; Klofac in litt.; pers. obs.) about a possible ectomycorrhizal association of H. rubellus with Abies, Alnus, Cedrus, Picea, Populus; however, they are not confirmed in the present study. Periode berbuah utama adalah musim semi (akhir April) hingga musim gugur (November to awal Desember).
