Aim of this work is to describe the diversity of teloschistaceae in the forest of Doui Thabet (Saida province, western Algeria). The order Teloschistales contains species of nitrophilous lichens that grow rapidly on nitrogen-rich substrates. There are Teloschistaceae containing anthraquinones, Teloschistaceae with sedifolia grey and Physciaceae rich in atranorine. After sampling and collecting various specimens between 2019 and 2021 in this forest; the identification revealed 22 species of the Teloschistaceae family reported for the first time from this region. The following five species are noted: B/astenia xerothermica, Caloplaca intern, Pyrenodesmia microstepposa, Usnochroma carphineum, and Variospora giomerata are new species for Algeria. Keywords: Lichen, Teloschistaceae, New species, Diversity, Algeria.
Introduction
The Teloschistaceae family is one of the largest families of lichenized fungi, it includes a significant number of genus and species (Lücking et al., 2016). The morphological, anatomical and chemical variation observed for the genus Caloplaca, make a richness with more than 1000 species (Mishra et al., 2020). A new classification of this family has been proposed by Arup et al., 2013, where a total of 39 genera are recognised, of which 31 are newly described. The new genera are: Athallia, Austropiaca, Bryopiaca, Caiogaya, Cerothaliia, Flavoplaca, Gondwania, Haiopiaca, OrientophHa, Pachypeitis, Parvopiaca, Rufopiaca, Shackietonia, Scutaria, Sirenophiia, Soiitaria, Squamuiea, Steiiaropistangis, Teioschromistora, Teioschromistora. The resurrected genres are Biastenia, Dufourea, Foiimannia, Gyaioiechia, Lepropiaca, Poiycauiiona, Pyrenodesmia and Xanthocarpia (Arup et al., 2013). The Teloschistaceae are characterised by the presence of parietin as a major by-product which gives a yellowish orange colour to the thallus and apothecia. Polarilocular spores and Teioschistes-type asci are observed. The character of the spores has always been important in determining the species, especially in the genus Caloplaca (Mishra et al., 2020). Teloschistaceae grow in moist, well-lit environments in temperate or Mediterranean climates. They occupy the surfaces and branches of trees of several species. They are found in the corticolous, terricolous and saxicolous types.
Study area
The forest of Doui Thabet has an area of 56.31 km2 with a distance of 14 km North-South and 30 km East-West of the province of Saida. It is part of the geographical area of the Tellian highlands. It is limited to the north by the localities of: Sidi Boubkeur and Ouled Khaled, to the west by the locality of Youb, to the east by the town of Saida and to the south by the locality of A'in el Hadjar. This forest is composed of four cantons, Sidi Ahmed Zega'i', Oum Touajine, Ras-el-Ma, and El-Ache (Terras, 2011). The bioclimatic Floor is cool semi-arid, with irregular and low rainfall between 300 and 370 mm/year. January and February are the coldest months of the year (3.3°C) while July and August are the hottest (35.5°C) (Baghdadi 2017). The soils of the region are limestone, red, and lithosols (Halitim, 1988). The frequent species in Doui Thabet forest are: Pinushalepensis M., Pistacia lentiscus L, Quercus coccffera L., Ampeiodesmos maurttanicus Poir., Rosmarinus tournefortii de noé, Asparagus acutifolius L, Globularia aiypum L., Cistus villosus L, Phiiiyrea angustifoia L., Caiycotome spinosa L., Stipa tenacissima L (Terras 2011) (Fig. 1).

Materials and Methods
In the forest of Doui Thabet, we used two sampling methods, the first method for sampling epiphytic lichens. The lichens were counted inside a quadra placed on the tree trunks. We took into account the 4 cardinal points of the tree (Truong, 2013). The information taken on these lichens followed the strict protocols of Wirth, 1997. The second for the sampling of saxicolous and terricolous lichens, we used the partial sampling method. In the field, after having chosen a surface much larger than the minimum area which is (0.5 m2) according to Roux, 1990. The lichens ecology and the nature of the substrate are very important for the lichens identification (calcicole and calcifuge lichens), hydrochloric acid (HCl) is used in the field to identify calcareous and non-calcareous soils and rocks. In the laboratory, specimens were carefully identified by observing their morphology and anatomy using spot tests to determine the compounds in the lichens that are necessary for identification (Kondratyuk et al., 2016). For anatomical studies sections of thalli and apothecia by hand section, spore measurements were performed in K (10% potassium hydroxide) (Holien and Palice, 2018). The spore measurements were estimated in water by calculating: (min-)X-sd-X-X+sd(-max) by the metrology software Piximetre 5.10. We note: (min) and (max) are the extreme values, (X) the arithmetic mean, and (sd) is the corresponding standard deviation. For the identification, determination and nomoclature of lichens, we used several keys and references such as: Les lichens étude biologique et flores illustrée (Ozenda et Clauzade, 1970), The lichens (Wirth, 1995), Guide des lichens de France, lichens des arbres (Van Haluwyn, C., and Asta, J 2017), Guide des lichens de France. Lichens of soils (van Haluwyn, C., Asta, J., and Boissière, J. C. (2014). Guide des lichens de France.

Results
The determination of the lichenic flora of the teloschistaceae family in the Doui Thabet forest (province of Sa'ida), revealed twenty-two (22) species of Teloschistaceae divided into 12 genera. The species reported for the first time in Algeria is marked with an asterisk (*). Concerning the classification and synonyms of the taxa, recourse was made to the updated inventory of lichens of Algeria by Ait Hammou et al., (2014), and to Lichenological exploration of Algeria II by Amrani et al. (2018).

*Blastenia xerothermica Vondrak, Arup and I.V. Frolov.
Blastenia is a genus of lichens in the Teloschistaceae family, the origin of Blastenia is dated to the beginning of the Tertiary Age. The genus Blastenia contains 24 species with two subspecies, each species strongly prefers a single substrate type, seventeen (17) species are found on organic substrates, and seven (7) on siliceous rocks, all groups tend to have a Mediterranean distribution, but some epiphytic species have much wider geographical ranges. Only (7) species have vegetative diaspores; they also produce apothecia, but with smaller spores (Vondrak et al., 2020). Blastenia xerothermica is a recently described species; it grows on the branches of trees and shrubs, more rarely on trunks. In the Mediterranean region there is a similar species, Blastenia hungarica. These two species have a different distribution and altitudinal range; note that Blastenia xerothermica is related to the Eu-Mediterranean scrub vegetation (Nimis, 2021). Also it differs by its more developed thallus, its rather visible black pycnidia, and its habitat mainly on deciduous trees (Roux et al., 2017). In Algeria, two species are reported, the first is Blastenia crenularia Gandoger (1883), Flagey (1888, 1895), Egea et al., (1990), Egea and Limona (1991), and the second is Blastenia ferruginea Durieu (1846), Nylander (1854, 1858b, 1878), Flagey (1895, 1896), Paris (1871), Hue (1891), Steiner (1902), Werner (1949), Djellil (1989), Alonso and Egea (2003), Bendaikha (2006), Rebbas et al, (2011), Boutabia et a., (2015), Bendaikha and Hadjadj-Aoul (2016), Boutabia (2016), (Amrani, et al., 2018).

*Pyrenodesmia microstepposa (Frolov, Nadyeina, Khodos. and Vondrak) Hafellner and Türk
The genus Pyrenodesmia is characterised by its crustose, endolithic to epilithic, thick thallus with short marginal lobes. The colour of the thallus and apothecia varies between grey and brown, most lichens of the family Teloschistaceae (Ascomycota) produce yellow, orange, red anthraquinone pigments, however, the genus Pyrenodesmia includes species in which the anthraquinone is absent and replaced by a grey pigment (Sedifolia grey) (Frolov et al., 2021). Vegetative diaspores are present in five species; apothecia are produced by all species, but are less frequent in the soridiate, blastidiate species. This genus is found on inorganic substrates, usually on calcareous rocks (Vondrak et al., 2019).
In Algeria the species reported are Pyrenodesmia agardhiana var. albopruinosa Flagey (1896), Pyrenodesmia agardhiana var. bullosa Flagey (1896), Pyrenodesmia chatybaea (Fr.) A.Massal Flagey (1896), Werner (1949), Rebbas et al., (2Q11), (Amrani, et al., 2Q19).

The genus Usnochroma S0chting Arup and Frôdén, is characterised by a crustos, pale yellow thallus without anthraquinones, the etymology of this taxon is by the presence of usnic acid which gives the thallus the yellowish green color. The apothecia are zeorines with a thin proper margin and a rusty orange disc, polarilocular spores with a very long septum. The thallus contains gyrophoric acid and usnic acid, while the apothecia contain parietin. The genus Usnochroma comprises two species: Usnochroma carphineum (Fr.) Sochting, Arup and Frôdén et Usnochroma scoriophiia (A. Massal.) Sochting, Arup and Froden (Arup et al., 2013). The genus Usnochroma is reported for the first time in Algeria by the species Usnochroma carphineum in the forest of Doui Thabet. Synonym: Amphiioma carphineum (Fr.) Bagl, Callopisma carphineum (Fr.) Trevis, Caloplaca carphinea (Fr.) Jatta, Physcia carphinea (Fr.) A. Massal, Squamaria carphinea (Fr.) Boistel (Nimis, 2022).

*Variospora glomerata (Arup) Arup, Sochting and Frôdén
The genus Variospora currently comprises twelve species and has recently been separated from Caooplaca s.lat. characterized by a more or less fertile thallus without orange pigments. The species with lobed thallus resemble those of the genus Caoogaya or even Rusavskia, but can be separated by the citriform spores or by the equatorial thickening of the spores. The crustacean species can be confused with several other species. By the presence of sublobes or microlobes on the thallus (Arup et al., 2013). In Algeria five species of the genus variospora are reported, vaiospora aurantia, variospora dooomiticoia, vaiospora flavescens, variospora haliincola, vaiospora velana (Amrani, Mark R. D. Seaward, et al., 2019), of which two species are reported for the first time from the Saida province variospora aurantia, variospora flavescens.

Conclusion
The diversity of Teloschistaceae in the Doui Thabet forest (Saida province, western Algeria) is very abundant on diverse substrates. They are found in this region on terriculous and saxicolous types. During our sampling mission, five new species were recorded for Algeria, as follows: Blastenia xerothermica, Caloplaca intern, Pyrenodesmia microstepposa, Usnochroma carphineum, and Variospora glomerata. The identification also revealed other species of the family Teloschistaceae reported for the first time for this region. They are listed as follows: Caloplaca cerina, Caloplaca rubeiiiana, Flavoplaca oasis, Gyalolechia flavovirescens, Gyalolechia fuigens, Gyalolechia fuigida, Kuettiingeria erythrocarpa, Kuettiingeria teichoiyta, Polycauliona poiycarpa, Pyrenodesmia aiociza, Pyrenodesmie heiygeoides, Rufbpiaca arenaria, Variospora aurantia, Variospora fiavescens, Xanthocarpia iactea, Xanthocarpia marmorata, Xanthoria parietina. The search for lichenic diversity constitutes a very important richness in medical potential. These species are very fragile and very resistant to the most hostile environments; their presence constitutes a good marker of global climate change.
