The sporulation rhythm in Nectria cinnabarina Tode ex Fr. is expressed by either concentric rings or spirals. The period is inversely proportional to the temperature and does not approach 24 hours; the rhythm is therefore noncircadian. The period of the zonation rhythm is lengthened by culturing the fungus on a dialysis membrane over the agar surface, on media solidified with an increased amoun...

F nuclear magnetic resonance spectroscopy was used to study the metabolism of 5-fluorouracil in four strains of Nectria haematococca which displayed similar sensitivities to growth inhibition by this compound but differed in their pigmentation. The major metabolites, 5-fluorouridine and alpha-fluoro-beta-alanine, were excreted into the medium by all four strains. The classical ribofluoronucleot...

descriptive tasks that will enable them to answer questions about how social life proceeds, and then they work toward explaining more formally why patterns appear in their data. Making the transition from ‘how?’ to ‘why?’ can be a dilemma, but the ethnographer’s folk culture provides facilitating resources for detecting and appreciating especially compelling descriptions. Recognitions of lumino...

The genus Nectria is typified by N. cinnabarina, a wood-inhabiting fungus common in temperate regions of the Northern Hemisphere. To determine the diversity within N. cinnabarina, specimens and cultures from Asia, Europe, and North America were obtained and examined. Their phylogeny was determined using sequences of multiple loci, specifically act, ITS, LSU, rpb1, tef1, and tub. Based on these ...
