Notes and News: News Reports of <em>Calamagrotis porteri</em> A. Gray From North Carolina

ABSTRACT <em>Hohenbuehelia aciculospora</em> (Agaricales), <em>Gloeomucro ventricosum</em> and <em>G. luteodiscus</em> (Aphyllophorales) are described as new. The first is compared with <em>Physalacria</em>.

ABSTRACT Distinct differences in the phytoplankton composition at upstream and downstream stations were documented for the Duplin River, Georgia. A phytoflagellate and cyanobacterial flora predominated the upstream station. Downstream diatoms and cyanobacteria were dominant. At the downstream station a winter-spring bloom was dominated by <em>Asterionella glacialis</em> Castracane and <em>Skeletonema costatum</em> (Grev.) CL., with the latter species also abundant in the autumn. The seasonal occurrence and general abundance of the 177 taxa recorded are presented. The general composition of the algal flora is similar to that previously reported for the southeastern continental shelf.

ABSTRACT A 16.1 hectare watershed at Coweeta Hydrologic Laboratory in southwestern North Carolina was clearcut in 1939-1940 and again in 1962. No timber was removed during the clearcuts. Present vegetation composition (woody and herbaceous species), and tree species distributions in relation to site characteristics were of primary interest. <em>Liriodendron tulipifera</em> had the highest basal area and Importance Value (IV) of all tree species; <em>Quercus prinus</em> had the highest density, <em>Acer rubrum</em> the highest frequency. Stand basal area in 1984, 21 years after the second clearcut was 20.82 m2 ha-l which is over 80% of that before the first clearcut. <em>Kalmia latifolia</em> and <em>Rhododendron maximum</em> have responded vigorously to past clearcuts; and, the herbaceous layer is far from depauperate. Of the site variables measured, those related to site quality were the best predictors of the dominant species and the community types. <em>Liriodendron tulipifera</em> and the Cove Hardwoods community type are highly

ABSTRACT Vegetation and soils are compared on two forested, lower north-facing slopes over marble and schist parent materials in northern Georgia. Moisture and parent material are probably the most important factors determining differences in soils and vegetation. Soils over marble have a mean pH of 6.1, ranging from 5.3 to 6.6. These soils.have a relatively high moisture, particle density, pore space, clay, stones and litter, total N and extractable, K, Ca, Mn, B, Cu and Zn; in contrast, soils over schist have a lower mean pH of 5.3, ranging from 4.6 to 6.0, relatively less of the above factors and higher sand, silt and extractable P, Fe, Na, Al, Si and Mo. The number of species per 100 m2 is greater over marble (36 vs 20). Herb species (31 vs 15) make up the largest part of the difference. Herbs crowd the forest floor over marble (111% cover) while a

ABSTRACT Fort Frederica, Saint Simons Island, Georgia was settled by English colonists in 1736. The fort and surrounding lands have undergone nine major phases of disturbance and regrowth since pre-colonial times. Written descriptions by colonial observers document the original predominance of evergreen oak-mixed hardwood forests on the upland portion of Saint Simons, instead of the contemporary successional pine forest. They also document the presence of extensive marshes and ponds, and many of which, including a pond outside the walls of the fort, are smaller or are no longer present. Records indicate the Indians, settlers, and slaves used fire for clearing dense vegetation. As a result of human activities, the fire regime on the island has probably changed from aboriginal times to the present, including a possible increase in large forest fires during the 19th century. The present vegetation consists of loblolly pine (<em>Pinus taeda</em>) with an understory of laurel oak
