Hortiboletus bubalinus

Ciri dan struktur

Basidiomes pileate-stipitate, xerocomoid, epigeal, small to medium-small sized. Ontogenetic development gymnocarpic. Pileus (2.9–)3.8–10.3(–13.5) cm broad, firstly hemispherical then persistently convex and finally broadly pulvinate-flattened, sometimes slightly depressed at centre, regularly to hardly unevenly shaped by shallow depressions, margin even to faintly wavy-lobed, initially involute then curved downwards or rarely completely plane, not or only a little extending beyond the tubes (up to 1 mm); surface matt, dry, but slightly greasy in aged basidiomes with moist weather, markedly wrinkled and finely pruinose in the early stage of development then tomentose with age, usually not cracked or occasionally areolate towards the peripheral zone; somewhat variable in colour, at first, dark garnet red or dark reddish-brown, but typically paler towards margin (pale orange to yellowish-orange), often later gradually fading to drab tinges and becoming orange ochraceous, sometimes with scattered pinkish hues, then evenly pale ochraceous brown, chamois olive to dull ochraceous buff, often retaining small and dispersed pale-reddish to ochraceous-orange zones (especially in the depressions) and with a thin, reddish-pink marginal band; aged basidiomes can completely lack reddish tones, although some basidiomes retain bright reddish tints with age; unchanging on handling or touching or when injured; subpellis layer pale pink to whitish buff. Tubes up to 12 mm long, at first, thin in side view then increasingly wider with age and shorter than the thickness of the pileus context, easily separable from the context above, adnate, but soon depressed around the stipe apex and shortly decurrent with a tooth, bright yellow to olive yellow then olive brown, bluing on cutting.

Habitat dan peran ekologis

solitary to gregarious or even subcaespitose, growing on litter, among grass or on bare soil, mainly in moist anthropogenic environments, such as public and private gardens, urban parks, or rural areas under a large array of ectomycorrhizal trees of the families Salicaceae, Malvaceae, Fagaceae, Betulaceae, Pinaceae, including preferably Populus spp. (P. alba, P. nigra, P. tremula, Populus hybrids), Tilia spp. (T. cordata, T. × europaea, T. platyphyllos), Quercus spp. (Q. cerris, Q. ilex, Q. petraea, Q. robur), and Fagus sylvatica, but sometimes also Picea spp. (P. abies, P. × fennica, P. pungens), Betula spp. (B. pendula), Carpinus betulus, Corylus avellana, Castanea sativa, Carya ovata, and Pinus radiata; some collections of H. bubalinus have been found in mixed forest with the presence of Pinus spp. (P. nigra, P. pinea, P. sylvestris), Cedrus (C. atlantica, C. deodara), Larix decidua, Salix alba, and Alnus glutinosa, but there are no finds in monodominant forest communities formed by these tree species alone (Oolbekkink (1991); Ladurner and Simonini (2003); Albert (2004); Muñoz et al. (2008); Musumeci (2008); Assyov and Stoykov (2011); Wilgan and Leski (2022), GP; Kasparavičius and Iršėnaitė (2023); Assyov in litt.; Cooper and Park in litt., GP; Klofac in litt.; Saar et al. unpubl., GP; pers. obs., GP).
