SPECIES, AUTHORITY T. airensis (Cookson) Kalgutkar & Jansonius 2000
LOCATION Australia, New Zealand and the Kerguelen Archipelago.
ORIG DESCRIPTION* Ascomata flattened-hemispherical, glabrous, 90-160 µm in diameter, composed of radiating hyphae united along their whole length, cells thin walled, cubical to rectangular, 2.5-5.5 µm thick and 3-13 µm long. Margin thin, entire. Ostiole well defined, 8 µm in diameter, surmounting a prominently-raised, dark brown, conical border composed of four or five layers of thick-walled cells, the base of which is 29.5 µm in diameter.
COMMENTS* This description is based on five specimens from the Sentinel Rock beds, the characters in which they appear to differ from N. setifer being evident in all of them. The main distinctions are the narrower ostiole, the conical form and degree of prominence of its border and the absence of setae. The finer texture of the ascomal membranes becomes evident when the specimen illustrated in pl. 11, fig. 7 is compared with specimens of N. setifer shown in pl. 11, figs. 3 and 5. A small piece of upper epidermis of Oleinites willisii from Yallourn shows two ascomata of Notothyrites in situ. These seem closer to N. airensis than to N. setifer, and are therefore provisionally placed in that species. No hyphae accompany these ascomata, so that the opinion formed from a study of detached examples that the mycelium of Notothyrites was evanescent is substantiated by them.

K&J REMARKS Reddy, Ramanujam & Srisailam 1982, p. 114, proposed the combination Trichothyrites airensis (Cookson), but did not provide the basionym or bibliographic details, and hence did not validly publish this combination.
