For microscopic examinations, free-hand sections of ascomata
were mounted in water, 5% KOH, 1% phloxine or cotton blue, and observed under light microscope (Olympus CX31).
Pacioni and Fantini (1997), who first studied and described the taxon in Italy, seemed to have used only very few ascomata
originated in Sardinia and Spain and selected, among macro-and microscopic features useful for differentiating the species from T.
in Muayala Natural Reserve near Arar city at the north-east of Saudi Arabia, has permit to obtain for the first time of relatively big ascomata
of Picoa spp.
Species of the order Pleosporales with applanate ascospores can be found in three families (Diademaceae, Hysteriaceae, and Pleosporaceae), which differ in the way the ascomata
a cleistothecia nonstromaticae in catervis parvis, 150-300 [micro]m in diametrer, superfycialia, aggregate, cinerea, glovosaevel, subglobosae.
The microscopic features of ascomata
and conidial heads were examined from wet mounts prepared in lactic acid under light microscopy.
Parallel evolution of hysterothecial ascomata
in ascolocularous fungi (Ascomycota, Fungi).
This genus is characterized by superficial ascomata
usually covered with hairs or setae (6); membranaceous peridium, consisting of several pseudoparenchymatous layers; asci that are clavate or fusiform (with biseriately arranged ascospores) or sometimes cylindrical (with uniseriately arranged ascospores), thin-walled, evanescent and without apical structures; scarce paraphyses that disappear before ascocarps mature (7); ascospores that are brown or gray-brown (never opaque or black), one celled, with one or sometimes two germ pores, and exuding as a dark, black, sticky mass (8).
Epigloea lives in association with algal films and it is still unclear the specificity of the relationship of the fungus with the algae since it is common to find different algal species below the fungal ascomata
. Although it was previously thought to be a lichen, modern works treat it as a highly adapted biotrophic parasitism (Dobbeler 1984).
Kernia bartlettii differs in having nonostiolate ascomata
as with other species of Lophotrichus, K.
