Anthostomella longispora W. H. Hsieh et al., Mycol. Res. 101: 897-898. 1997.

 Description: The fungus is visible on the host surface as irregularly circular, minute, flat, grayish pustules which are perforated by central, barely erumpent ostioles. Ascomata 410-515 μm in diam., immersed, scattered, surrounded by sparse hyphae, subglobose with a papillate neck up to 136 μm long, beneath an ill-developed, intraepidermal clypeus, which consists of epidermal cells permeated by dark brown hyphae and extends as loose hyphae downwards in te cortical cells. Peridium 29-39 μm thick of two layers, the outer layer of a dark brown textura intricate, the inner layer of compressed cells, brown outside and becoming hyaline inside. Asci 148-168 × 11-14 μm, unitunicate, cylindrical, 8-spored, shortly stipitate, stipe up to 20 μm long, with an amyloid, cuneiform apical apparatus about 6 μm long and 4 μm wide; paraphyses 3-4 μm wide, numerous, septate, hyaline. Ascospores 17-25 × 7-9 μm, aseptate, elliptical, end rounded or tapered, straight to slightly inequilateral, uniseriate, dark brown, with a longitudinal slit as long as the spore, surrounded by a mucilaginous sheath.

 Note: Five species of Anthostomella have been reported on Smilax (Francis,1975).They are A. contaminans (Dur. & Mont.) Sacc., A. sepelibilis (Berk & M. A. Curtis) Sacc., A. smilacis Fabre, A. bicincta Syd. and A. ludoviciana Ellis Langl. Francis (1975) has given a full description of the first three species but has only included the latter two species in the synoptic key. Short descriptions of these two species can be found in Saccardo (1891,1928). A. longispora similar to A. contaminans (Dur. & Mont.) Sacc. (Francis, 1975) in the shape of ascospores but differs from it by the larger sized ascomata, asci and apical apparatus.
