Hortiboletus engelii

Ciri dan struktur

Basidiomes pileate-stipitate, xerocomoid, epigeal, small to medium-small sized. Ontogenetic development gymnocarpic. Pileus (4–)5–13(–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, finely areolate towards the peripheral zone or with minute to coarse cracks over the whole surface especially with dry weather and showing a yellowish or somewhat pinkish subpellis layer resembling some areolate Xerocomellus species (Simonini 1998b); margin initially involute then extended or even uplifted, regular to wavy-lobed, acute and slightly exceeding the pileal context, whitish at the very beginning for a thin strip, but soon concolourous; of extremely variable colours, but generally dark brown up to black-brown at the beginning, then fading to ochraceous, ochraceous yellow, buff, yellowish-brown, olivaceous brown, greyish-brown, olive grey, grey or also pinkish-red, orange-red, ochraceous red, ochraceous pink, reddish-brown, typically fading in age, although some basidiomes maintain a carmine red tint over the entire life-cycle; unchanging or becoming slightly darker on handling or when injured. Tubes up to 15 mm long, at first adnate, later emarginate or slightly decurrent with a tooth, initially lemon or chrome yellow, later greenish-yellow to olive brown, unchangeable to weakly bluing when injured. Pores large, wider than 1 mm (up to 1.5–3 mm) in old basidiomes, roundish to angular, concolourous with the tubes, in mature basidiomes with orange-rusty spots, unchangeable to weakly bluing when bruised and later becoming dirty brownish.

Habitat dan peran ekologis

solitary, gregarious in small groups or even subcaespitose, growing on bare soil, on litter or in the grass, often in anthropogenic environments, shrublands, less frequently in undisturbed forests, under a large array of ectomycorrhizal broadleaved trees and shrubs, including preferably Quercus spp. (Q. cerris, Q. coccifera, Q. frainetto, Q. ilex, Q. incana, Q. robur, Q. petraea, Q. pubescens, Q. suber), Fagus sylvatica, Tilia spp. (T. cordata, T. platyphyllos), Carpinus spp. (C. betulus, C. orientalis), sometimes also Betula spp., Castanea sativa, Corylus avellana, Halimium halimifolium, Pinus spp. (P. halepensis, P. pinea, P. sylvestris, P. wallichiana), and Populus spp. (P. alba, P. tremula) (Engel et al. (1996); Ladurner and Simonini (2003); Peintner et al. (2003), GP; Krpata et al. (2008), GP; Sarwar et al. (2016), GP; Leonardi et al. (2020), GP; pers. obs., GP). Some collections of H. engelii have been found in mixed forests with the presence of Picea abies and Ostrya carpinifolia, but there are no findings in monodominant forest communities formed by these tree species alone. Moreover, there are some indications of a possible association with Cedrus deodara (Kjøller in litt.; Szmidla et al. in litt.; pers. obs.), but these data have not yet been confirmed by molecular studies nor by our examined material.
