An annotated list of 80 aphyllophoroid fungi species registered on the Gunib Plateau (Inner-mountainous Dagestan, North-Eastern Caucasus) with detailed information on substrata, habitats, localities, and collection numbers of specimens deposited in the Mycological Herbarium of the Komarov Botanical Institute RAS (LE) is provided. Among them 39 fungal species are recorded for the Republic of Dagestan for the first time, including Phlebia caspica is new to Russia and Lindtneria chordulata is the second record for Russia. Seven species (Amylocorticium cebennense, A. subsulphureum, Henningsomyces candidus, Kneiffiella microspora, Leucogyrophana sororia, Mucronella flava, Vararia ochroleuca) are new to the Caucasus. Data on the Gunib record of Thelephora caryophyllea, red-listed species in the Republic of Dagestan, is presented.

INTRODUCTION

The Gunib Plateau is situated in the northwestern part of the Inner-mountainous Dagestan and is not only a well-studied area for many wildlife species of higher vascular plants, mosses, and lichens, but also a local concentration of rare and endemic representatives (Ignatov et al., 2010; Asadulaev, Sadykova, 2011; Omarova, 2013; Urbanavichus, Ismailov, 2013; Ismailov, Urbanavichus, 2014; Abdurakhmanova, Sadykova, 2015).

Studies on the funga of the Gunib Plateau were initiated by the authors in 2018. Several publications are devoted to the species diversity, molecular identity and ecology of tomentelloid (Volobuev et al., 2019; Ivanushenko, Volobuev, 2020) and poroid fungi (Volobuev et al., 2021), as well as to aphyllophoroid fungi species dwelling on Juniperus oblonga wood (Volobuev, Ivanushenko, 2020). Habitats of rare species of aphyllophoroid fungi, subsequently included in the new edition of the Red Data Book of the Republic of Dagestan (2020), were recorded on the Gunib Plateau.

Corticioid fungi remain one of the poorly studied ecological and morphological groups of xylobiont fungi on the plateau. In this regard, our work is devoted to updating the information on their diversity, occurrences and ecology, as well as supplementing the already available data on other groups of aphyllophoroid fungi in the Gunib Plateau (Inner-mountainous Dagestan).

MATERIALS AND METHODS

Study area. The Gunib Plateau is shaped like a truncated cone. The internal slopes of the plateau are dramatically different: the surface of the southern slope is represented by stone slabs with little or no soil, the slope is well-insolated, while the northern slope is characterized by gentle topography and high humidity and covered with forest (Gabibova et al., 2009; Ismailov, Urbanavichus, 2014, Dibirov et al., 2012). Forest-forming species are Pinus kochiana, Betula litwinowii, B. pendula, and B. raddeana. Communities dominated by other tree species (Salix caprea, Populus tremula, Carpinus betulus, etc.) are less common and form the lower and upper edges of the forest belt. The slopes are divided by the canyon of the Gunibka River, with Alnus incana growing along its bed (Ismailov, Urbanavichus, 2014). The shrub layer in the plateau forests is monotonous (Juniperus oblonga, Rosa canina, R. oxyodon, R. pulverulenta, R. spinosissima, Cotoneaster racemiflorus, and Euonymus verrucosus) (Gabibova et al., 2009). The climate of the plateau is continental. The relative humidity is 65%.

Sampling. Basidiomata of aphyllophoroid fungi were collected in September – October of 2018–2021, May 2019 and June 2021 during the field survey by the authors in main forest types of the plateau territory. Fungal specimens have been gathered from various kinds of wood substrata presented by fallen trunks and branches, dry attached branches, stumps, living shrubs and trees. The geographical coordinates and altitudes of studied localities were determined using the Garmin 64st GPS-navigator. The investigated localities (Fig. 1) in the annotated list of species are numbered as follows:

7 – mixed pine-dominated forest on a north-facing slope (42°23′26.6″–50.6″ N, 46°55′11.7″–56′10.3″ E, 1567–1759 m a.s.l.).

Identification and examination of specimens. Microscopic identification of dried collected specimens were performed using a LOMO Mikmed-6 microscope (Russia), an AxioScope A1 microscope (Germany), a LOMO Mikmed-6 microscope (Russia) with a standard set of chemicals (5% KOH, Melzer′s reagent, 0.1% Cotton Blue) based on key monographs on European corticioid and poroid fungi (Bernicchia, Gorjón, 2010, 2020; Ryvarden, Melo, 2017) as well as some modern articles on the taxonomy of these fungal groups. Data on the fungal species distribution is based on available publications and according to the updated database on Agaricomycetes diversity (Bolshakov et al., 2017, 2019). Voucher specimens are deposited in the Mycological Herbarium of the Komarov Botanical Institute RAS, Saint Petersburg (LE).

RESULTS

Altogether 80 species of aphyllophoroid fungi from 45 genera and 10 orders of Agaricomycetes (Basidiomycota) are reported, including 39 species new to the Republic of Dagestan. Phlebia caspica is registered for Russia for the first time. Lindtneria chordulata is the second record for Russia. Seven species (Amylocorticium cebennense, A. subsulphureum, Henningsomyces candidus, Kneiffiella microspora, Leucogyrophana sororia, Mucronella flava, Vararia ochroleuca) are new to the Caucasus. Most of fungal species have been collected from dead wood of Pinus kochiana and Betula spp. (Fig. 2) which are the main forest-forming trees on the territory of the Gunib Plateau.

DISCUSSION

Phlebia caspica is registered for Russia for the first time by basidiomata growing on a fallen decaying trunk of Betula sp. on the Gunib Plateau. This species was described by N. Hallenberg based on specimens collected on fallen branches and a fallen trunk of Fagus orientalis and other deciduous trees in Iran (Hallenberg, 1980). Only more than 20 years later, Ph. caspica was found in France (Eyssartier, 2006), Spain (De-Esteban-Resino, Gorjón, 2016), and Ethiopia (Spirin, Ryvarden, 2018). The species is distinguished by cream-coloured to light ochraceous odontioid hymenophore, subulate leptocystidia and ellipsoid basidiospores slightly concave on the adaxial side (Fig. 3). Among substrata inhabited by Ph. caspica there are noted both angiosperms, namely Alnus and Fagus (Hallenberg, 1980; De-Esteban-Resino, Gorjón, 2016), and gymnosperms, in particular, Juniperus (Spirin, Ryvarden, 2018). Our finding from the Gunib Plateau is fully compliant with the protologue and extends the list of substrata occupied by this species to include birch (Betula sp.) wood.

Lindtneria chordulata is listed for the second time for Russia following a record from Arkhangelsk Oblast (Svetasheva et al., 2017). This species is distributed sporadically in Europe (Bernicchia, Gorjón, 2010). Both Russian specimens of L. chordulata were collected in pine forests from Pinus fallen trunks, Pinus sylvestris in Arkhangelsk Oblast and P. kochiana in the Republic of Dagestan. Based on the suspected sensitivity of this fungus to any anthropogenic impact, Lindtneria chordulata is included in the Red Data Book of Arkhangelsk Oblast (Aksenova et al., 2020) as a declining species (category 2).

Kneiffiella microspora belongs to remarkable and little-known in Russia species. Previously this fungus was registered only in five Russian regions, including the north-west of the European part (Arkhangelsk and Leningrad Oblasts), the Volga Region (Nizhny Novgorod and Samara Oblasts), and the Urals (Sverdlovsk Oblast) (Spirin, 2003; Bolshakov et al., 2016). Our Gunib record of K. microspora on fallen branches of Betula sp. is the first finding for the Caucasus. Besides this, species such as Amylocorticium cebennense, A. subsulphureum, Henningsomyces candidus, Leucogyrophana sororia, Mucronella flava, and Vararia ochroleuca are also new to the Caucasus. All of them were collected on the dead wood of Pinus kochiana, except for Henningsomyces candidus, which grew on fallen branches of Betula sp.

Two species of the genus Rhizoctonia, R. fusispora and R. ochracea (Fig. 4), are re-collected from the Gunib Plateau, having been previously known from this area as aphyllophoroid fungi associated with Juniperus oblonga (Volobuev, Ivanushenko, 2020). Our new finds of Rhizoctonia fusispora are obtained from Pinus kochiana wood, and Rhizoctonia ochracea is found on a fallen trunk of Betula sp.

A new substratum inhabited by Kneiffiella abdita in the Gunib Plateau is noted. This fungus is considered as a very rare species in Europe (Bernicchia, Gorjón, 2020). K. abdita was registered within the studied area on fallen trunks of Pinus kochiana (Volobuev et al., 2021). We have now supplemented the substrate range of the species with a find on Betula sp. dead wood.

During mycological survey carried out the population of ectomycorrhizal fungus Thelephora caryophyllea has been monitored. This species is regionally protected and included in the Red Data Book of the Republic of Dagestan (2020) as a vulnerable species (category 3). The only Gunib locality of Th. caryophyllea in pine forest with mosses is currently known in Dagestan.

CONCLUSION

The species diversity of aphyllophoroid fungi discovered on the Gunib Plateau, both those presented in this study and those published previously (Volobuev et al., 2019, 2021; Ivanushenko, Volobuev, 2020; Volobuev, Ivanushenko, 2020), indicates the special nature conservation value of the area. This fact is confirmed, on the one hand, by the findings of fungal species new to the Caucasus and, on the other hand, by the presence of rare species and taxa with a sporadic distribution. The latter may exhibit particular requirements for environmental conditions and the state of forest ecosystems, requiring large-measured woody debris and stable moisture regimes. Further studies on aphyllophoroid fungi in the Gunib Plateau will allow not only to reveal new species for this area, but also to determine species of fungi the most sensitive to anthropogenic disturbance.
