Pisolithus albus (Sclerodermataceae), a new record for Tunisia

Abstract

Pisolithus albus was recently collected for the first time in Tunisia. This ectomycorrhizal fungus is found associated with Eucalyptus occidentalis, a new symbiotic relationship, in the urban area of Tunis. The new record of this fungus on this tree permit to expand our knowledge on the ecology and distribution of P. albus in Tunisia. The finding is also important since this fungal symbiont has great potential in forestation efforts. Data on the morphology, molecular identification, distribution and, ecology for P. albus in Tunisia are presented for the first time.

Pisolithus albus (Sclerodermataceae), a first record from Egypt

“…Acacia nilotica). This fungus was reported previously in ectomycorrhizal association with Acacia and Eucalyptus species from different countries (Díez et al 2001;Founoune et al 2002;Martin et al 2002;Kanchanaprayudh et al 2003;Singla et al 2004;Jaouani et al 2015;Gargano et al 2018;Lebel et al 2018;Chouhan & Panwar 2021). During the present study, P. albus basidiomata were reported for the first time in the vicinity of two potential hosts, Paspalum distichum and Dodonaea viscosa; however, the mycorrhizal connections with these two hosts were not investigated.…”

“…Pisolithus albus is one of the most common gasteromycetes in the world, which is recorded here for the first time from Egypt to extend our knowledge about its distribution in Africa to four countries, namely: Egypt (this study), Morocco (Yakhlef et al 2009), Senegal (Duponnois & Bâ 1999) and Tunisia (Jaouani et al 2015). Morphologically, Pisolithus albus specimens from Egypt are slightly different than collections from other localities.…”

“…It was introduced by Albertini and Schweinitz (1805) to accommodate the type species Pisolithus arenarius. Members of this genus were recorded from various habitats with regard to temperature, nutrient levels and heavy metal concentrations, and has been recorded from tropical, subtropical and temperate regions (Watling et al 1999;Martín et al 2013;Rusevska et al 2015;Jaouani et al 2015;Crous et al 2016;Mifsud & Mifsud 2022). Pisolithus species make mycorrhizal associations with different plant species in the families Casuarinaceae, Dipterocarpaceae, Fagaceae, Myrtaceae and Pinaceae (Marx 1977;Malloch & Kuja 1979).…”

Pisolithus Albus, Newly Recorded From Pakistan

“…Pisolithus albus is an ectomycorrhizal species, characterized by off-white to ochraceous, subglobose to piriform basidiomata with echinulate basidiopores (Ducousso et al 2012). It is a widespread taxon which has been reported from Australia, Brazil, India, Italy, Kenya, Malaysia, Morocco, New Caledonia, New Zealand, Senegal, Thailand and Tunisia (Hosaka 2009, Trierveiler-Pereira & Baseia 2009, Jourand et al 2010, Jaouni et al 2015, Gargano et al 2018, Lebel et al 2018. Molecular phylogenetic analysis carried out by Phosri et al (2012) and Lebel et al (2018) clustered several collections of P. albus in to P. albus complex, some of which were previously misidentified.…”

The first record of Pisolithus arhizus (Sclerodermataceae, Basidiomycota) in Central Asia

“…30 species globally (https:// www.indexfungorum.org/names/). The genus is characterized by fruit bodies of variable shape and size, often with a well-developed rooting base (Jaouni et al, 2015). Most species are widely distributed across temperate to tropical regions and form ectomycorrhizal (ECM) associations with a variety of woody plants (Marx, 1977;Chambers, Cairney, 1999;Rusevska et al, 2015).…”
