 Remarks:There are only two other species of Hypoxylon known to have a stromatal surface characterized by vinaceous shades and orange KOH-extractable pigments. These are H. fendleri Berk. and H. retpela Van der Gucht & Van der Veken.
Hypoxylon retpela was described originally from Papua New Guinea (Van der Gucht & Van der Veken 1992) and has been reported from Indonesia and Taiwan (Ju & Rogers 1996), as well as Thailand (Phosri et al. 2008). Although H. fendleri was also indicated as occurring in Indonesia and Taiwan by Ju & Rogers (1996), as well as in Thailand by Phosri et al. (2008), this species actually appears to have a distribution centered around the Caribbean Sea and the Gulf of Mexico (the states of Campeche and Quintana Roo in Mexico, the island of St. John and French Guiana), and the holotype was collected in Venezuela (Ju & Rogers 1996).
Both H. fendleri and H. retpela differ from H. pseudoretpela in having larger ascospores (9–12 µm against 7.5–9 µm) and a perispore that is dehiscent in 10% KOH. It is also noteworthy that the specimens of H. pseudoretpela collected in Thailand uniformly displayed a strong discharge of ascospores, so that the envelopes were always covered with a thick spore deposit on the inside.
