Bactrospora integrispora Seaver, Mycologia 16: 8. 1924. Type. VIRGIN ISLANDS. St. Thomas: on decorticated wood, 10 Mar 1923, Seaver 754 (NY, holotype), syn. nov. Seaver's name, appearing in a mycological journal, was not picked up by Zahlbruckner and thus not included by Egea & Torrente. (Also omitted, Seaver's report of Bactrospora dryina (Ach.) Massal. from North Dakota (Mycologia 1: 112. 1909.) is Schizoxylon berkelyeanum (Dur. & Lév.) Fuckel s. lat.) The Aptroot specimen from Key Largo was incorrectly assigned to Dade County instead of Monroe County in Egea and Torrente (1993). Bactrospora macrospora R. C. Harris Henssen in Henssen and Thor (1990) transferred this species to Melampylidium Stirton. I am uncomfortable with this on several grounds. First, the decision is based on material from North Carolina which the authors admit differs from my description of B. macrosporum. Second, I am cited for pointing out the different ascospore type. This is true but this was before Egea and Torrente's (1993) treatment of Bactrospora and I was simply ignorant of the range of ascospore variation in the genus. I did comment on the identity of the ascomatal type within Bactrospora. Third, Egea and Torrente (1995) present evidence for synonymizing Melampylidium with Bactrospora. Until more convincing evidence for recognizing Melampylidium and B. macrospora as a member of the genus, I prefer to retain the species in Bactrospora. Bactrospora nematospora R. C. Harris = B. myriadea CHIODECTON Ach. Only a single species, C. malmei Thor, is in North America, and it is diagnosed in the key to genera. Two other species C. perplexum and sp. Buck 3254 would seem to belong in Syncesia Taylor (Tehler, 1993) but there is as yet no treatment of the species. CRESPONEA Egea & Torrente This genus was recently separated from Lecanactis and revised by Egea and Torrente (Mycotaxon 48: 301-331. 1993). They reported C. proximata from Florida. 1. Ascospores 3-4(-5)-septate, 15-22(-24) × (4-)4.5-5.5 µm; margin black, raised, cracked; disk chartreuse pruinose; Alachua County........................... C. flava (Vainio) Egea & Torrente 1. Ascospores 5-7(-8)-septate, 25-38(-40) × 5-7(-7.5) µm; margin black, thick, slightly raised, ± smooth; disk chartreuse pruinose; Monroe County (Keys)............................................... ....................................................................................................... C. proximata (Nyl.) Egea & Torrente NOTES Cresponea flava (Vainio) Egea & Torrente This species is close to C. chloroconia (Tuck.) Egea & Torrente. They annotated a Calkins collection, purportedly from Florida, as C. chloroconia but did not cite it in the publication. The Cresponea is associated with sterile Chaenotheca furfuracea (L.) Tibell and is surely not from Florida. Cresponea flava is new to North America. FLORIDA.
