The clypeus is strikingly beautiful, being very thick and dark (Fig. 88). 

 and very small in diameter. The perithecial wall and lack of stroma deny 

 relationship with the Dothideales and clearly establish relationship with 

 the Clypeosphaeriaceae and apparently with the genus above named in 

 which there was only one species viz. S. theisseni Syd. on Pithecolobium 

 from which ours differs in ostiole, paraphyses, and spore shape.
