Abstract: The present article reports five heterobasidiomycetous taxa, viz., Dacryopinax
spathularia (Dacrymycetaceae),
Exidia glandulosa, Pseudohydnum gelatinosum (Exidiaceae), Tremella fuciformis, and T. mesenterica
(Tremellaceae), based on collections made from West
Bengal, India, with their morpho-anatomical
details. Dacryopinax
spathularia is reported from Odisha
and Uttar Pradesh while Tremella fuciformis and T. mesenterica
are reported from Chhattisgarh.
Keywords: Heterobasidiomycetes, jelly fungi,
taxonomy, West Bengal.
Five
jelly fungi were collected from different corners of West Bengal, India, and
are reported herein with detailed morpho-taxonomic
details.
The state of West Bengal has a wide range of phytogeographic
regions extending from the coastal areas (of Bay of Bengal) to the subalpine
regions of the eastern Himalaya. Each of
these regions is unique in terms of various ecological conditions such as
temperature, humidity, salinity, rainfall, altitude, edaphic factors, etc. that
provide a wide range of habitats for the luxuriant growth of different types of
macromycetes.
The ‘jelly fungiʹ belong to the
class Heterobasidiomycetes, characterized by the
presence of greatly swollen gelatinous basidiocarps, basidia that lobed and often divided by transverse, oblique
or longitudinal septa, and prominent sterigma
(Webster & Weber 2007). Most of the
jelly-fungi are saprotrophs that preferably grow on
dead and decaying plant parts. The
present manuscript reports five Heterobasidiomycetous
fungi viz., Dacryopinax spathularia
(Schwein.) G.W. Martin, Exidia
glandulosa (Bull.) Fr., Pseudohydnum
gelatinosum (Scop.) P.
Karst., Tremella fuciformis Berk., and Tremella mesenterica Retz.
with their morphological details. This is a series of our earlier works dealing
with the exploration of macromycetes diversity of
West Bengal (Acharya et al. 2017a,b,c;
Tarafder et al. 2017).
Materials and methods
The specimens were collected during
field trips in monsoon seasons (2010–2017) from corners of West Bengal,
India. Macro-morphological and
ecological features of each collection were noted in the field and subsequently
photographed. The colour
codes and terms used were in accordance with Kornerup
& Wanscher (1978). Microscopic features were
obtained from freehand sections of dried specimens by mounting with 10% KOH,
Congo red and Melzerʹs reagent with the help of Carl
Zeiss AX10 Imager A1 phase contrast microscope. Measurements of 30 basidiospores
of each of the specimens were examined.
Q value denotes length/breadth ratios of basidiospores
and the mean value is underlined.
Identification was done with the help of standard literature (Speairs 1957; McNabb 1965; Ellis & Ellis 1990; Zhishu et al. 1993; Kuo 2006,
2007, 2008a,b; Pippola & Kotiranta
2008; Shirouzu et al. 2009). The voucher
specimens were deposited in the Calcutta University Herbarium (CUH).

Remarks: Dacryopinax spathularia is well characterised
by its spathulate fruit body coloured
yellow-orange; presence of thick-walled, cylindrical marginal hyphae; absence
of inflated vesicles and hyphal pegs in the abhymenium; and presence of 0–1 septate
basidiospores (McNabb 1965; Shirouzu et al.
2009). This is a widely distributed
taxon and previously been reported from Japan, North America, and China etc.
(McNabb 1965; Zhishu et al. 1993; Shirouzu et al.
2009). It was reported from Rajamunda, Odisha, growing on
logs of Shorea robusta
(Tiwari et al. 2013).
The species was also recorded on wood from Saharanpur, Uttar Pradesh
(Butler & Bisby 1931). The present collection matches well with the
description made from North America (McNabb 1965); however, according to
Shirouzu et al. (2009), basidiospores of the specimen
from Japan were found to be sub-globose to reniform, while the Indian specimen showed mostly
cylindrical basidiospores with the range varying from
oblong to bacilliform (Q=1.6–3.0). The
specimen reported from China was found to have 1–2 septate
basidiospores at maturity, but the basidiospores of our collection showed one septation at maturity.
Among morphologically similar taxa: Dacryopinax indacocheae
has foliose fruit body coloured tan and presence
of inflated vesicles (McNabb 1965); Dacryopinax
formosus primarily differs by the presence of hyphal pegs in abhymenium layer; Dacryopinax aurantiaca
differs by its dingy white to cream or pallid tan-coloured
stipe and abhymenial surface, and considerably longer
basidiospores (up to 13.5 × 5 µm); Dacryopinax elegans has
larger fruitbody (12–50 mm) coloured
deep amber-brown to black-brown, thick-walled basidiospores
with 3-septations at maturity. Dacryopinax yungensis differs
by the presence of inflated vesicle-like cells in cortical layer, and
comparatively larger (11–14 × 4.5–6.5 µm), 3-septate basidiospores.
Exidia glandulosa (Bull.) Fr.
Syst. mycol. (Lundae) 2(1): 224 (1822)
(Fig. 2, Image 1b)
Fruit body 22–25 mm long, 10–16 mm
broad, turbinate, fleshy, gelatinous, irregularly folded to cerebriform,
reddish brown (8E5) to dark brown (8F4) to black when fresh, becoming greyish
brown (8F3) to black, hard, crust-like when dry, surface with dot-like
glands. Odour mushroomy.
Basidiospores 11–13.1–13.5(–15) × (4.5–)5–5.6(–6.5)
µm, Q=1.5–2.4–3.2, oblong to cylindric, allantoid, dark brown (7F5) at maturity, smooth, inamyloid, oil granules present with KOH. Phragmobasidia
11–17 × 8–12 µm, globose to ellipsoid, hyaline,
smooth, longitudinal, cruciate septate, 2–4 spored, basally stalked; stalk of basidia
7–14.5 × 1.8–3.5 µm, septate, hyaline, smooth; sterigmata 14–54 × 3.5–5.5 µm, hyaline. Hyphae 2–5.5 µm
broad, smooth, with clamp-connections.
Habit and habitat: Gregarious to confluent, growing on dead and decayed
dicotyledonous woods.
Specimen examined: CUH AM 219, 10.viii.2013, 22.279720N & 88.454720E,
elevation 8m, Gocharan, South 24-Parganas, West
Bengal, India, coll. A.K. Dutta & P. Pradhan.
Remarks: Characteristic features of Exidia
glandulosa includes the presence of brown to
black turbinate, gelatinous fruit bodies that often coalescing together to form
masses, dotted by minute glandular structures, cruciate septate,
stalked basidia and allantoid
basidiospores.
The Indian collection nicely matches with the description of Ellis &
Ellis (1990); however, the habitat of our collection was other dead
dicotyledonous wood as compared to the Britain collection that was reported to
be oak and hazel. It was reported from Nilgiris, Tamil Nadu (Montagne 1842). Among morphologically similar taxa: Exidia plana
differs by its effused fruit body (Roberts 2001) that lacks dot-like glands on
its surface. Exidia
truncata Fr. has fruit bodies that are not
confluent and remain largely free from the substrate, and larger basidiospores (14–22 × 5–7 µm; Ellis & Ellis
1990). Exidia
saccharina differs in having caramel to dark
brown fruit bodies lying flat on the substrate (Ellis & Ellis 1990). Exidia recisa differs by its amber to dark brown coloured fruit bodies that are not confluent and becomes
flabby and drooping when old (Ellis & Ellis 1990).
Pseudohydnum gelatinosum (Scop.) P. Karst
Not. Sällsk. Fauna et
Fl. Fenn. Förh. 9: 374
(1868)
(Fig. 3, Image 1c)
Fruit body 21–39 mm high. Pileus 14–28 mm,
fan-shaped, glossy, gelatinous, dull red (8C3) to reddish-brown (9D4) when
fresh, becoming dark brown (8F4) when dry, hard, cartilaginous; lower hymenial surface covered with dense, soft teeth or spines,
teeth 1–3 mm long, white (9A1). Stipe
15–18 × 7–13 mm, lateral, reddish brown (9D4) when fresh, becoming dark brown
(8F4) on drying.
Basidiospores (5–)6–7.2(–9) × (5–)6–6.8(–7.5) µm,
Q=1–1.1–1.3, globose to sub-globose,
hyaline, apiculate, smooth, thin-walled, oil granules
present when viewed with KOH. Basidia 11–15 × 7–11 µm, globose
to sub-globose or ellipsoid, hyaline, thin-walled, inamyloid, smooth, 2–4 septate
(cruciate), oil granules present when viewed with KOH, basally stalked, stalk
5–29 × 2–3.5 µm, 2–4 spored; sterigmata
5–25 × 2–4 µm, 1-septate, sometimes bearing bifurcation near the tip,
smooth. Hyphae 2.5–4.5 µm broad, smooth,
hyaline, branched, thin-walled, clamp-connections present. Hymenium unilateral, wavy
due to the presence of teeth.
Habit and habitat: Solitary to scattered, on humus mixed soil.
Specimen examined: CUH AM197, 22.viii.2012, 27.018050N & 88.564720E,
elevation 1697m, Lolaygaon, Darjeeling District, West
Bengal, India, coll. A.K. Dutta & P. Pradhan.
Remarks: The presence of characters like a glossy, fan-shaped, gelatinous pileus with the lower (hymenial)
fertile surface covered with dense, white soft teeth or spines can easily
identify Pseudohydnum gelatinosum
in the field (Ellis & Ellis 1990).
It is distinct from other taxa in being the only toothed member of the
jelly fungi (Emberger 2008).
Pseudohydnum gelatinosum has been previously reported from India (Das 2009). The present collection shows little smaller
cap (14–28 mm vs. 40–90 mm) and larger basidiospores
(5–9 × 5–7.5 µm vs. 5–6 × 4–5.5 µm).
Apparently, Dacryopinax elegans resembles the present taxon with regard to colour, structure, and texture but is easily distinguished
from it when the lower part of pileus is examined (Kuo 2015).
Tremella fuciformis Berk.
Hooker’s J. Bot. Kew Gard. Misc. 8: 277 (1856)
(Fig. 4, Image 1d)
Fruit body 43–63 mm long and 35–42
mm broad, white (1A1), firm gelatinous, translucent, mucilaginous when fresh,
becoming horny, thin, grey (3B1) to yellowish-grey (3B2) coloured
when dry, repeatedly lobed or forked with margins flexuous to folded,
sessile. Odour slightly fishy.
Basidiospores (6–) 6.5–8.4–9(–10) × (5–)5.5–6(–7) µm,
Q=1.1–1.3–1.5, subglobose to broadly ellipsoid,
smooth, hyaline, inamyloid, apiculate,
with 1 oil guttule.
Phragmobasidia 11–14 × 6.5–10 µm, subglobose, becoming longitudinally cruciate septate, 2–4 septate at maturity,
thin-walled, hyaline, oil granules visible when mounted with KOH, 4-spored; sterigmata 10–33 × 2–4 µm, cylindrical. Conidia 8–15 ×6–9 µm, subglobose to broadly ellipsoid, smooth, hyaline. Swollen cells 11–20 × 6–11 µm, globose to subglobose to
ellipsoid, abundant, hyaline, oil granules present when viewed with KOH. Hyphae 2.5–5.5 µm broad, hyaline, thin
walled, branched, clamp-connections present.
Habit and habitat: Solitary, on dead and decayed dicotyledonous wood.
Specimens examined: CUH AM536, 14.viii.2017, 22.883050N & 88.763610E,
elevation 6m, Gobardanga, North 24 Parganas, West Bengal, India, coll. K. Acharya;
CUH AM543, 14.vii.2017, 26.321940N & 88.436380E,
elevation 37m, Debi Bari, Cooch Behar, India, coll. K. Acharya.
Remarks: Tremella fuciformis
is characterised by its pure white, translucent,
gelatinous fruit bodies with lobed margins, and the presence of cruciate-septate phragmobasidia (Speairs 1957). It
has previously been reported from several countries such as China, Brazil, and
North America (Burt 1921; Olive et al. 1948; Speairs
1957; Zhishu et al. 1993). The Chinese specimen differs from the present
collection in having slightly smaller basidiospore
(5–7 µm diam.); however, the present specimen was found to be identical to the
description made from Brazil and North America (Burt 1921; Olive et al. 1948; Speairs 1957). From
India it was reported growing on logs of Shorea
robusta from West Bengal (Banerjee 1947) and Jagdalpur, Chhattisgarh; on Pterocarpus marsupium and
from Keshkalghat, Chhattisgarh (Tiwari
et al. 2013).
Tremella fuciformis is morphologically similar to T. reticulata;
however, T. reticulata grows on the ground or
on very rotten stumps and it differs by having a larger (up to 80mm long and
150mm broad), erect, reticulated fruit body that is irregularly forked upwards
giving rise to tapered tips (Speairs 1957; Kuo 2008a).
Tremella mesenterica Retz.
K. svenska Vetensk-Akad. Handl., ser. 1 30: 249 (1769)(Fig. 5, Image 1e)
Fruit body 18–33 × 13–30 mm, folded
into lobes, cerebriform, gelatinous, light yellow
(4A5) when fresh, becoming orange (5A6) to greyish orange (5B6), horny and
crust-like when dry. Sessile. Odour mushroomy.
Basidiospores 14–16–18 × 14–15–16.5 µm, Q=1–1.1–1.2, globose
to sub-globose, smooth, hyaline to pale yellowish
(3A3), apiculate, oil granules visible with KOH. Phragmobasidia
25–29 × 22–27 µm, globose to sub-globose,
2–4 celled, longitudinally or obliquely (cruciate) 4-septate at maturity,
thin-walled, hyaline to pale yellowish (3A3), inamyloid,
smooth, oil granules present when viewed with KOH, 4-spored; sterigmata 18–144 × 4.5–6.5 µm. Conidia not observed. Swollen cells 14–33 × 11–27 µm, sub-globose to ellipsoid to oblong, terminal or sub-terminal,
stalked, smooth, hyaline. Hyphae 2–5 µm
broad, thin-walled, branched, hyaline to pale yellow (3A3), clamp-connections
present.
Habit and habitat: Solitary to caespitose, on dead and
decayed dicotyledonous wood.
Specimens examined: CUH AM538, 10.viii.2017, 22.786380N & 88.355000E,
elevation 17m, Barrackpore, North 24-Pargana, West
Bengal, India, coll. K. Acharya; CUH AM545,
16.vii.2016, 23.400830N & 88.501380E, elevation 20m, Krishnanagar, Nadia, West Bengal, India, coll. K. Acharya.
Remarks: Distinguishing features of Tremella
mesenterica includes a bright yellow, lobed, cerebriform fruit body, presence of cruciate septate phragmobasidia with much
longer sterigmata (Ellis & Ellis 1990; Pippola & Kotiranta
2008). The specimen of our collection is
similar in characters with the one described from Finland (Pippola
& Kotiranta 2008) except having slightly longer sterigmata and presence of distinct oil droplets in basidia and sterigmata. From India, it was reported from Jagdalpur, Chhattisgarh, growing on logs of Shorea robusta (Tiwari et al. 2013).
With regard to the colouration and size of the fruit body, Tremella
mesenterica is similar to T. aurantia (Pippola & Kotiranta 2008).
However, T. aurantia differs from T.
mesenterica in having rather smaller basidiospores (5.5–9 × 4.5–7 µm) and basidia
(ca. 9–13 µm wide) (Pippola & Kotiranta
2008).
