The monotypic fossil genus Cucurbitariaceites was described by Kar et al. (1972from the Tura Formation (Palaeocene, 6656 mya) in Nongwal Bibra, Garo Hills, Meghalaya, India. This genus is characterized by subcircular to circular Pseudoperithecia, outer region darker than inner, laevigate. Asci are equal or unequal in size, cylindrical to somewhat bulging at the tips in the mature stage. No true paraphysis was observed, but in some specimens, the basal part of asci may join together to form a broad, irregular, mesh-like structure. Cucurbitariaceites bellus has been recorded from various states of India, e.g. Andaman and Nicobar Islands (Mandal et al. 1996), Arunachal Pradesh (Mandaokar 2000a), Assam (Mandaokar 199119932005Chakraborty 2004), Kerala (Varma & Patil 1985), Meghalaya (Tripathi 1989Saxena et al. 1996), Mizoram (Mandaokar 2000b2002a2003Kar et al. 2010) and Nagaland (Mandaokar 2002b).
