SPECIMEN EXAMINED. — Tunisia . Mogods, Bizerte Governorate , Delegation of Sejenane:Cap Serrat, with sporophyte, 37°12’17.00”N , 09°13’50.60”E , 3 m a.s.l. (site 2019-65), 08.IV.2019 , Ben Osman & Hugonnot (TUN[TUN2019-68]). REMARKS Sphaerocarpos europaeus was collected in a swampy willow ( Salix pedicellata Desf. ) grove on mud deposited on large aerial roots. The species is characterized by its reddish-brown spore tetrads measuring 135-170 µm in diameter. The distal surface has 4-6 large alveoli. The papillose lamellae bordering the alveolae reach 10-13µm high, and are spineless at the angles. Ros et al . (2007) noted that Bischler (2004) reported Sphaerocarpos texanus (now considered as S. europaeus ; Hodgetts et al . 2020) in Tunisia without any details of locality and that its presence therefore requires verification. The present mention can then be considered as the first reliable citation for Tunisia . Sphaerocarpos europaeus is a Mediterranean-Atlantic species presently known in Europe and North Africa ( Ros et al . 2007 ).
