Phillipsia

Abstract: Five species of Phillipsia Berk, are reported from Central America: P. domingensis, P. crispata, P. lutea, P. hartmannii, and P. costaricensis. Two of these, P. lutea and P. costaricensis, are new ...

Abstract: Our knowledge of the fungi of Santo Domingo is comparatively meager. Berkeley (5) appears to have been the first to make a study of the fungous flora of this Island. His work is based on a collection made by A. Salle and eighteen of the sixty-seven species studied were described as new. Later Berkeley (6), in connection with his studies of Australian fungi, reexamined his Santo Domingan species, Peziza domingensis, and made it the type of the new genus Phillipsia. With the exception of a few short papers by Gonzalez Fragoso and Ciferri (13), (14), (15), (16), (17), Ciferri and Gonzalez Fragoso (9), dealing with the fungi, and a note by the writer (28) on the myxomycetes of that Island, all references to Santo Domingan fungi are scattered within the literature of other regions. The fungus Aecidium Cordiae P. Henn. was described from a specimen collected in Santo Domingo, by Ehrenberg, and pub? lished by Bresadola, Hennings and Magnus (7) in connection with their studies on Porto Rico fungi. Leveille (18) and Lloyd (19) refer to the fungi collected by Poiteau in Hispaniola. It is doubtful, however, whether these fungi belong to Santo Domingo proper since there is no record of Poiteau having ever collected outside of Haiti. Fee (11) describes a new species of Sphaeria from this Island, S. divaricata, which was renamed by Saccardo (21) Xylaria divaricata (Fee) Sacc. Saccardo (l.c.) also re? examined most of Berkeley's Santo Domingan species of Hypo? xylon and changed them to Xylaria. Reference is also made by Saccardo (22) to a rust described by deCandolle from this Island. In his studies of the Uredinales, Arthur (1), (2), (3), (4) includes Santo Domingo in the geographical distribution of many of the species. Burt (8) refers to species of Stereum collected by Taylor and by Stevenson; Olive and Whetzel (20) extend the range of Endophyllum Stachytarpetae to this Island, wThile the writer (29) 66

Abstract: It is commonly assumed that by Carboniferous times trilobites were all but extinct, represented by only a handful of species belonging to the genera Phillipsia or Griffithides and found occasionally at a few localities. In fact, there is afar greater abundance and diversity of forms than is usually realized, and in parts of the Carboniferous System trilobites can be as stratigraphically important as many other fossil groups.

Abstract: Rickiella edulis is reported from Argentina for the first time and is documented with photographs of fresh specimens and molecular data Previously the species was known as R transiens (= Phillipsia transiens) and was reported from southern Brazil and Paraguay Phylogenetic analyses based on SSU rDNA and LSU rDNA shows its placement in a monophyletic family, the Sarcoscyphaceae The relationship of Rickiella, Phillipsia and Nanoscypha however could not be resolved from phylogenetic analyses of the ITS, SSU, and LSU rDNA sequences The excipular tissue of Rickiella is shot through with regularly spaced channels and cavities Because of this feature, the genus Rickiella is recognized as distinct from Phillipsia Phillipsia and Nanoscypha are morphologically distinct but diversity within Phillipsia remains a topic for further research A new tribe in the Sarcoscyphaceae is proposed to accommodate the genus Wynnea
