SPECIES, AUTHORITY T. nilssonioptericola Krassilov 1967, p. 95, pl. 3, fig. 1.
LOCATION Southern Primorsk, Russia.
ORIG DESCRIPTION* [Diagnosis] Stroma epiphyllous, flat, linear, the length is up to 3 mm, width up to 140 µm. The edge is paddle-shaped. Ascomata are developed as localized thickenings under the stroma, they are round, dark and about 55 µm in diameter.

[Description]: The mycelium forms the texture of the stroma. Stromata are flat, fan-shaped, the length is up to 3 mm, width ranges from 77 to 140 µm. The lobes are oval, and occasionally produce a short lateral projection at an acute angle to the long axis of stroma. The hyphae in the middle part are stretched along the axis, and those closer to the margin are fan-shaped. Thickness of the hyphae is about 3 µm. After treatment with Schulze's solution, the stromata become light yellow and get an appreciably dark border that is about 4 µm thick. A similar border can also be seen on the extant Trichopeltis stroma (Fraser, 1936). A part of the stroma is shown in pl. 3, fig. 1. A young ascoma in the form of a rounded dark spot can be seen in the left corner of fig. 1. The perithecia growing under a stroma represent round localized thickenings with the diameter of about 58 µm. On Nilssoniopteris and Cladophlebis frigida leaves.
COMMENTS* The described fungus has a broad similarity to many modern species of Trichopeltis and, as well, with the fossil Trichopeltinites pulcher Cookson. It differs very insignificantly from the latter in the stromatic structure and in branching. Yet, we consider it an independent species, taking into account a significant difference in geological age and geographical location.

K&J REMARKS Specimens of Trichopeltinites nilssonioptericola Krassilov appear similar to T. pulcher Cookson 1947a. Creation of a new species based essentially on differences in age and geographical location may not be pertinent, particularly as these differences can be useful in geographical correlation, and the stratigraphic range of the species.
