“…They are primarily represented by Rhizopogon guzmanii, R. luteolus, R. rosealus, R sublateritius, R. villosulus, R. vulgaris and a recently discovered species R. himalayensis (Mujic et al, 2019). Though there is substantial literature available on Rhizopogon species diversity and distribution from India (Singh, 1992;Lakhanpal, 1996;Sharma et al, 2009;Beig et al, 2011;Kumar and Sharma, 2011;Chauhan et al, 2014;Malik et al, 2017;Paul et al, 2019;Singh and Passari, 2019 ;Suneja et al, 2019), yet studies about in vitro synthesis of Rhizopogon species, ectomycorrhizae are limited (Mohan et al, 1993, Reddy and Natarajan, 1996, Singh et al, 2020. As far as the mycorrhizal characterization aspect is concerned, not much has been reported/ documented.…”

Rhizopogon himalayensis (Castellano, S.L. Miller, Singh & Lakhanpal) A.B. Mujic & M.E. Sm., comb. nov. -an edible truffle-like fungus- normally exists in a symbiotic association with Cedrus deodara (Roxb.) Loud. Because of this important association and the ecological significance as per the available literature attached to this fungus, the present study was undertaken with a specific objective to test the mycorrhizal viability of this mycobiont with this important tree species of Himalaya -the theme tree of Himachal Pradesh. An attempt to investigate and record morphological and anatomical characteristics and variations in this mycorrhizal association was also made in nursery conditions using pure culture (wheat grain spawn) of R. himalayensis. The seedlings grown and inoculated in the nursery were harvested after six months for further examination, including the microscopic details. The study and subsequent analysis revealed that that mycobiont had invaded most of the feeder roots, imparting a typical swollen appearance to the mycorrhizal root tips. These root tips were light ochre with moderately thick plectenchymatic fungal mantle with occasional clamp connections on the inner layer of the fungal mantle. The root surface, as seen, was found smooth and frequently covered with a loose aggregation of inter-woven hyphae that uniformly pervaded the epidermis extending into the inter-cortical spaces of outer cortical cells and formed a characteristic Hartig net. Thus, results obtained in fact for the first time, presented an in-depth analysis of the morphological and anatomical characteristics of R. himalayensis and C. deodara association.

“…However, when lactic acid was added, the roughness of hyphae disappeared immediately and the oily droplets after a few hours. Fine roughness of emanating hyphae and outer hyphae of rhizomorphs was also observed for S. citrinum (Waller et al 1993 ; see also the drawing in Mohan et al 1993 ), while the presence of warts on the surface of the outer mantle hyphae was reported for S. sinnamariense (Ingleby 1999 ). Up until now, oily droplets have not been recorded for any other Scleroderma ectomycorrhizae, so this might be used as a distinguishing feature for S. areolatum .…”

“…Rhizomorph nodia, which were observed for S. areolatum , were also reported for S. bovista on Populus alba (Jakucs and Agerer 1999 ) and S. citrinum on Larix decidua (Richter and Bruhn 1990 ), but not for S. citrinum on other host species (Brunner et al 1992 ; Mohan et al 1993 ; Waller et al 1993 ); in some cases, information on rhizomorph structure is not detailed enough. It seems that a quite common characteristic of Scleroderma ectomycorrhizae are also inflated or swollen hyphae, which are sometimes referred as cystidia.…”

“…It seems that a quite common characteristic of Scleroderma ectomycorrhizae are also inflated or swollen hyphae, which are sometimes referred as cystidia. Inflated or swollen hyphae at distal ends of hyphae emanating from the mantle surface were reported for S. sinnamariense (Ingleby 1999 ), S. dictyosporum (Ingleby 1999 ) and S. citrinum (Mohan et al 1993 ), while for S. citrinum (Mohan et al 1993 ; Waller et al 1993 ) and S. verrucosum (Chu-Chou and Grace 1983 ), they were described for the surface of rhizomorphs. In our samples of S. areolatum , they occurred on the surface of thicker rhizomorphs, where they were locally distributed, and at some tips of emanating hyphae.…”

“…Various Scleroderma species have been described as forming ectomycorrhizae, indicating its broad host range and distribution (Table 1 ), but detailed descriptions are available only for S. citrinum (Mohan et al 1993 , Waller et al 1993 ), Scleroderma bovista (Jakucs and Agerer 1999 ) and Scleroderma sinnamariense (Ingleby 1999 ). Scleroderma areolatum has been described previously only briefly from Italy as forming ectomycorrhizae with Castanea sativa (Meotto et al 1994 ).…”

Scleroderma areolatum ectomycorrhiza on Fagus sylvatica L.

Despite its broad host range and distribution and its potential applications in commercial plantation forests, comprehensive descriptions of Scleroderma ectomycorrhizae are available only for Scleroderma citrinum, Scleroderma bovista and Scleroderma sinnamariense. This study provides a morphological and anatomical description of tree nursery derived ectomycorrhizae of Scleroderma areolatum on Fagus sylvatica, grown for several years in a climatized room. Ectomycorrhizae of S. areolatum were silvery white with abundant rhizomorphs; all mantle layers were plectenchymatous, rhizomorphs of type E, with prominent emanating hyphae with thick cell wall. The distal ends of emanating hyphae of rhizomorphs were inflated and often merged with other emanating hyphae. All parts of the mycorrhiza were clampless. In hyphae of the outer mantle layer, rhizomorphs and emanating hyphae, oily droplets were observed that did not stain in sulfo-vanillin and disappeared in lactic acid after a few hours. Although the phylogenetic analysis positioned the newly described ectomycorrhiza together with Scleroderma verrucosum and Scleroderma cepa in a single clade with a taxon name SH005470.07FU, the ectomycorrhizae of these three species can be morphologically well separated based on rhizomorph type.
