Abstract: Routine surveys of mycologically unexplored forest areas of Jharkhand, followed by a thorough examination of macro-fungal collections reveal two hitherto unrecorded poroid species (Basidiomycete) for Indian mycobiota namely, Ganoderma elegantum and Perenniporia bambusicola, and a less known hydnoid wood-rotting species Beenakia fuliginosa. Detailed taxonomic descriptions coupled with illustrations are provided for all three taxa and compared with allied taxa.


Keywords: India, Jharkhand, Wood-rotting macrofungi.



Jharkhand is one of the richest states of India in terms of forest and mineral resourses. Forests are mainly dominated by many economically important plants including sal (Shorea robusta) and bamboos, which are major sources of forest products for the native tribal people as well as being a rich host of wood rotting macrofungi. Rajmahal Hills and Koderma Wildlife Sanctuary are parts of this state and remain neglected from the mycological point of view except for a few sporadic reports (Currey 1874; Bodding 1925‒1940; Panigrahi 1966; Anonymous 2013; Parihar et al. 2013). A critical examination of the specimens and a study of the relevant literature (Sorbhoy et al. 1981; Bilgrami et al. 1991; Jamaluddin et al. 2004; Ranadive et al. 2011; Sharma 2012; Tiwari et al. 2013) revealed two new records and one less known to Indian mycobiota and are presented here with descriptions and illustrations of macro- and micro-morphological details.



Materials and Methods

Macro-fungal surveys of tropical deciduous (50–450 m) forest areas have been undertaken during the monsoon (August–September) season from 2008 to 2014. Macro-morphological characterization was made with the fresh basidiomata in the field or in the base camp (Fig. 1). Field photographs of these fresh macro-fungi and their habitats were captured with the aid of a Nikon D200s and Olympus C-5060. Colour codes and terms (mostly) are based on the Methuen Handbook of Colour (Kornerup & Wanscher 1978). After the Macromorphological characterization basidiomata were dried with the help of a wooden drier.

Micromorphological characterization was undertaken with the help of a light microscope: Olympus CX 41 from the free hand sections of the dry basidiomata mounted in a mixture of 5% KOH, phloxin, Congo red, and separately with Melzer’s reagent or lacto-phenol and cotton blue. Measurements of spores were noted from 20 randomly chosen basidiospores. Spore-measurement and quotient indicating length-width ratio (Q = L/W) are presented here as minimum-mean-maximum. Herbarium name follows Holmgren et al. (1990).







Taxonomic enumeration

Distribution: Zambia; India, Tamil Nadu and Jharkhand (Rajmahal Hills & Koderma Wildlife Sanctuary).

Notes: Genus Beenakia includes those hydnoid macro-fungi which bear macromorphological features like pileate, stipitate basidiomata with rounded, spinose hymenophore and micro-morphological features like septate clamped smooth to warted generative hyphae; clamped basidia and ellipsoid to pip-shaped or almost navicular ornamented, hyaline to yellowish, inamyloid basidiospores (Reid 1955 ; Cunningham 1958; Mass Mass-Geesteranus 1971; Parmasto & Ryvarden 1990; Nunez & Ryvarden 1994). In the family Clavariadelphaceae this genus presently holds seven valid species including Beenakia fuliginosa worldwide (www.index The present species was erected by Mass-Geesteranus (1977) as Psathyrodon fuligionsus on the basis of basidiomata and spore colour, but after a critical study of type materials including Indian collections as well as re-collected materials from type locality on same substrate, it appears that these features are insufficient to raise B. fuliginosa as under new status by placing as P. fuliginosus. Hence P. fuliginosus becomes a synonym of B. fuliginosa (Parmasto & Ryvarden 1990).

This is an undocumented species in the regional and national mycoflora of India and so far only collected once from Tamil Nadu by Parmasto in 1979 (Parmasto & Ryvarden 1990). Its habitat is also interesting because it grows on the base of living stumps of Shorea robusta (as observed from present study); however, a few specimens were also found to grow on Morus alba L. and other trees and shrubs from the study areas.

Macro- and micro-morphologically, the present specimens are fairly within the circumscriptions provided by Parmasto & Ryvarden (1990) and Nunez & Ryvarden (1994) supported by the illustration of Mass-Geesteranus (1977); except the color of basidiomata (Pink), which may be due to geographical variation. Significant taxonomic features like monomitic clamped generative hyphae, which are thick-walled and granular insubiculum and pip shaped, verruculose, obliquely apiculate, adaxially flattened basidiospores associated with present specimens strongly recommends placing them as B. fuliginosa. Moreover, supplementary features of basidiospores as revealed from scanning electron microscopic (SEM) studies also agreed with that of Julich & Star (1983), and Parmasto & Ryvarden (1990).







Ganoderma elegantum Ryvarden, Syn. Fung. (Oslo) 19: 81 (2004). (Image 2 & Fig. 3)

Basidiomata 40‒58 mm high, annual, humicolous (perhaps attached to buried roots of bamboos), laterally stipitate, light weight. Pileus 15‒20 × 12‒17 mm and 8‒10 mm thick near the stipe; surface indistinctly zonate in the middle while more distinct and sulcate towards the margin, glabrous, laccate, dark brown (7F6‒7F7). Margin up to 0.5mm wide, obtuse, distinct to indistinct from hymenial surface, sterile, concolourous with hymenophore. Pore surface pale yellow (4A3) to pale orange (5A3); pores 5‒7 per mm, angular to rounded, white when fresh and ochraceous white at maturity. Stipe 40‒45 mm long and 4‒5 mm in diameter, cylindrical, bottleneck like near base, ring like zones in the stipe, laccate, glabrous, sulcate, and concolourous with pilear surface. Pilear context 1‒5 mm thick, distinctly duplex, two black dense bands originating at the bottom of the stipe extended up to the pileus, upper part brown (6E5) and lower part dark brown (6F5); stipe context distinctly zonate, outer layer light brown, 1‒2 mm thick and inner layer 2‒3 mm thick, dark brown. Tubes 1‒3 mm long, straight, paler than context.

Cuticle layer 20‒50 µm thick, yellowish brown; cuticular cells 17‒42 × 8‒12 µm, thick-walled to solid, apically widened with a narrow lower part, smooth, apically amyloid. Hyphal system dimitic; generative hyphae 2.5‒5 µm wide, thin-walled, clamped, branched, rare, smooth, hyaline. Skeletal hyphae 2.5‒9 µm wide, thick-walled, wall 1‒3 µm thick, abundant, arboriform, smooth, hyaline to yellowish-brown. Basidia and basidioles not found. Basidiospores 8‒9.7‒12 × 5.5‒6.3‒7.5 µm, Q=1.33‒1.51‒1.8, oblong ellipsoid, truncate or rounded at the apex, acyanophilic, inamyloid; exospores smooth and hyaline; endospore ornamented, brown.






Specimens examined: MEH-13-087 (CAL), 26.viii.2013, India, Jharkhand, Rajmahal Hills, Sahibganj District, Borio-block, Dalabari Village, 25002’34.8”N & 87039’55.3”E, 106m, on soil probably attached to buried bamboos root, near dead bamboo thickets, coll. M.E. Hembrom.

Distribution: Ecuador; India (Jharkhand, Rajmahal hills).

Notes: So far this species has been reported only from its type locality (Amazonas jungle in Ecuador confined to the neo-tropical belt) as mentioned by Ryvarden (2004) and this is the second collection from the paleo-tropical belt indicating its rare but wide range of distribution. Though the present description is based on two basidiomata collected from the Rajmahal Hills, Jharkhand, it holds enough macro- and micro-morphological features like long slender stipe, black melanoid bands in the pale brown context and oblong spores (Ryvarden 2004) to recognize the present collection as Ganoderma elegantum. The present specimens slightly differ as compared to type, in having apically rounded as well as truncate basidiospores (‘apically rounded’ in the protolouge). The stipe is shorter as compared to the type material (stipe is up to 150mm long). Another taxon G. stipitatum Murill appeared to be allied due to a combination of characters like amyloid cuticular cells, duplex context separated by melanoid band (as Ryvarden 2004) but its short to almost negligible stipe, more club like and evenly widened cuticular cells and small basidiospores as compared to the present taxon (8‒12 × 5.5‒7.5 µm) separate it from the previous one. Tiwari et al. (2013) reported 17 species of Ganoderma from central India, but it excludes the present species.







Perenniporia bambusicola Choeyklin, T. Hatt. & E.B.G. Jones, Fungal Diversity 36: 122 (2009) (Image 3 & Fig. 4)

Basidiomata 3‒55 × 2‒25 mm and up to 0.5‒1 mm thick, annual, resupinate, effused, corky when dried. Hymenophoreporoid to decurrent; pores 4‒7 per mm, angular to round, deep orange (5A7) to light orange (5A5–5A4) when fresh and light orange (5A4) when dried; dissepiments thin and entire; violet to black with KOH. Margin indistinct, white mycelium present near periphery but disappear when dried. Subiculum very thin ochraceous to pale orange. Tubes tough-fibrous to leathery, decurrent, concolorous with hymenophore.

Hyphal system dimitic. Generative hyphae 1.5‒3.5 µm wide, thin-walled, smooth, clamped, occasionally branched, infrequent in subiculum and tubes, hyaline. Skeletal hyphae 2.5‒5 µm wide, thick-walled, wall up to 1µm thick, arboriform with stalk and side branches, dominating in subiculum and tubes, interwoven but more or less parallel near substrate, crystalline particles present changing into violet colour with 10% KOH, hyaline to more or less dextrinoid when agglutinated. Fusoid cystidioles 16‒27 × 3.5‒5 µm, thin-walled, smooth, hyaline. Basidioles 12‒13 × 5.5‒7.5 µm, clamped at base, smooth, hyaline. Basidia 12‒16 × 5‒7 µm, 4-sterigmate, sterigmata 3‒5 µm long, clamped at base, smooth, hyaline. Basidiospores 3.5‒4.87‒6 × 2.5‒3.28‒4 µm, Q = 1.21‒1.49‒2, oblong ellipsoid, truncate, thick-walled, smooth, hyaline, cyanophilic, weakly dextrinoid.








Specimens examined: MEH-66240 (CAL), 26.viii.2014, India, Jharkhand, Rajmahal Hills, Sahibganj District, Taljhari block, Paderkola Village Dhamdhamia, 60m, 24055’57.0”N & 87045’09.1”E, on dead bamboo-roots and fallen leaf litter of bamboos, coll. M.E. Hembrom.

Distribution: Thailand, China and India (Jharkhand, Rajmahal Hills).

Notes: Whereas the species’ epithet itself indicates the present taxon’s habitat (confined to bamboos exclusively), the habit shows (resupinate orange hymenophore which turns into violet black with KOH) very characteristic and separating features from its close allies Perenniporia corticola (Corner) Decock and P. xantha Decock & Ryvarden. Perenniporia xantha can be demarked with the help of bright yellow hymenophore, arboriform skeletal hyphae and host asangiospermic wood (Decok & Ryvarden 1999; Zhao & Cui 2012) (never on bamboos). Its macro and microscopic characters are fairly within the range of type (Choeyklin et al. 2009) supported by the circumscription of Zhao & Cui (2012) except, its basidiospores, which are slightly larger than that of Zhao & Cui (2012; 4‒5.3 × 2.5‒4 µm) but well agreeable with protolouge (3.5‒5.8 × 2.2‒3.9 µm as Choeyklin et al. 2009) to determine it as P. bambusicola.







Along with a large number of other fleshy fungi, the wood-rotting macrofungi face a serious threat from the high anthropogenic pressure causing habitat loss day by day due to mining, road construction, overgrazing, jhoom-cultivation and forest fires (Fig. 1). Species by species approach (for conservation) is not the realistic way in a poor country like India. Therefore, it is an exigency of conserving the habitats as such in a sustainable manner because livelihoods of the Santhal and Paharia tribes depend upon the forest (Rajmahal Hills) resources of these areas (Fig. 1). This approach will not only protect the species in discussion but also the large mycobiota of these areas will be conserved. So far no assessments have been done for wood-rotting mycobiota of these regions as per the recent IUCN categories of their occurrences, and hence more extensive surveys and ecological studies are needed to conserve the wood rotting fungi in the near future.
