INTRODUCTIONChacón (2002) has the most recent comparison of species belonging to the genus Endoxylina Romell. The genus has a wide range of concepts and is defined by the presence of uni- to triseptate ascospores and stromata with valsoid or eutypoid shapes (Ju et al. 1996). According to Sivanesan (1977) and Chacón (2002), two species have been divided; the first has ellipsoid, subfusoid to ovoid ascospores, while the other has cylindrical to allantoid ascospores. There are just four species in the first category, which includes a species from the Russian Far East. Two of these, namely Endoxylina citricola Ou and E. mori Sawada, were reported from tropical eastern Asian locales, in Taiwan (Sawada 1959) and southern China (Teng 1938), respectively. Diabetic endoxylina spora Only the type locality in Turkmenistan (Frolov 1970) is known for Frolov, but all of Asia is home to E. indica Maharkar & V.G. Rao. With the exception of North American E. allantospora (Ellis & Everh.) Shoemaker & Egger and Mexican E. tehuacanensis S. Chacón, most species of the second group—Endo-xylina astroidea (Fr.) Romell, E. anserina (Pers. :Fr.) E. Müll, E. crocea Kirschst., E. pini Sivan., and E. polyspora E. Müll.—with cylindrical to allantoid ascospores are European. Due to the presence of either 3-septate ascospores (E. tehuacanensis) or valsoidstromata (E. allantospora), these latter taxa differ from European species. Methods: Standard procedures were used to conduct microscopic analyses. Using a Zeiss Primo Star, asci and ascospore measurements, observations, and photos were taken. Axio-164, a digital camera, and a microscope Microsoft Vision. A Nikon D40x digital camera was used to take the stromata photos.
