SUMMARYA brief history is presented of mycological collections in New Mexico. Isolation of water-molds from some bodies of water in the Sangre de Cristo Mountains of northern New Mexico and isolation of fungi from the desert soils and gypsum sands of the Tularosa Basin in southern New Mexico resulted in reports of 77 species of fungi. Included were 7 species of Saprolegniaceae from elevations exceeding 6700 ft, and 60 species of Fungi Imperfecti.

摘要:

SUMMARYThe genera,PenicilliumandAspergillus, formed two of the more important components of the fungus population of the air at Manhattan Kansas, during a two-year study from September, 1956, through August 1958. Results are based only on studies of colonies obtained by exposing plates of rose bengal-streptomycin agar in the Pady-Rittis and General Electric samplers since spores of these genera could not be identified from exposed silicone slides.Penicilliumformed 6.1% of the total colonies whileAspergillusrepresented 5.4%.The occurrence of both genera was greatly affected by climatic conditions. In general, however,Penicilliumappeared to prefer warmer weather whileAspergilluspreferred cooler temperatures.A total of 41 species ofPenicilliumwas identified, of whichPenicillium oxalicumwas the commonest, representing 56% of all coloniesAspergilluswas represented by 23 species, withA. amstelodamiandA. nigerformed 32% and 23%, respectively, of the total colonies.

摘要:

SUMMARYThe development ofLamproderma arcyrionemais traced from the first emergence of the fruiting plasmodium on the surface of a rotten log to the final maturation of the sporangia. The formation of the stalk and capillitium is described and found to follow the pattern typical of members of the Stemonitaceae. The chromosome number is reported to be N = 53±2.

摘要:

SUMMARYThe growth of the wood-rotting fungi,Polyporus tulipiferus, P. palustris, Lenzites trabea, Fomes subroseus, Peniophora giganteaandLentinus lepideus, was determined in L-, D- and DL-alanine and in L-, D- and DL-aspartic acid, separately, in shake culture in a basal synthetic medium. Generally, the amounts of growth in the racemic mixtures at 0.003 per centtotalnitrogen concentration approximated one-half of that in the L-isomers at the same total nitrogen concentration, as would be expected if the D- forms were not utilized and the amounts of growth were directly proportional to the“utilizable”(L-) nitrogen concentrations. Generally, also, mycelial weights in the racemic mixtures at 0.006 per cent total nitrogen were the same as the amounts of growth in the respective L-isomers at 0.003 per cent nitrogen, and approximated double the growth in the racemates at 0.003 per cent nitrogen. In no case was there utilization of D-isomers alone, and in only one case ---L. trabeain alanine---was there some evidence for the assimilation of the D-isomer of the racemate in the presence of the L- form. In one or two cases there was a suggestion of some inhibition of growth by the D- form in the racemic mixture. The isomeric configuration of amino acids is an important factor in their utilization by wood-rotting fungi.
