摘要:

SUMMARYSix diploids ofAspergillus parasiticusinvolving 12 genetic markers were analyzed by means of the parasexual cycle. Heterokaryotic heads consisted of homokaryotic and heterokaryotic conidial chains. Due to the intra-conidial complementation between spore-color mutants, heterokaryotic spores were green (wild-type). Gene action for spore-color determination was autonomous. The analysis of two mutants impaired in aflatoxin production revealed the independent segregation of genes involved in the biosynthesis of aflatoxin. Loci for four auxotrophs, one spore-color mutant, and two aflatoxin mutants were assigned to four linkage groups.

摘要:

SUMMARYDactylella oviparasiticais described as a new species. The species is distinctive in that fusiform, multiseptate conidia are borne on single sporogenous cells which function as short conidiophores. Relatively complex media are required for growth and sporulation ofD. oviparasitica, and the fungus also requires light for sporulation.Dactylella oviparasiticawas isolated from root-knot nematode (Meloidogynesp.) egg masses and is capable of actively parasitizing eggs of the nematode.

摘要:

SUMMARYThe new taxaFloseulomyees, based onF. floridaensis, Oneopodium simmonsiiandOramasia hirsutavar.ramosaare described, illustrated and compared with related taxa. Twenty-one other species are recorded from Florida with relevant annotations, and the nomenclatural change,Ramiehloridium verrueosum(syn.Veronaea verrucosa) is made.

摘要:

SUMMARYIn April 1976, we discovered that the in vitro fungistatic action of Gamastan toPhialophora dermatitidiscould be inhibited by the goat antiserum to human immunoglobulins IgG, IgM and IgA. In July and October last year we proved on several occasions that the experimental cladosporiosis of white Swiss mouse caused byP. dermatitidiscould be prevented or cured by the application of Gamastan intravenously. Clinical therapeutic trials against mycoses with Gamastan and other human immnoglobulin preparations are being made.

摘要:

SUMMARYWall ontogeny during sporidial budding inSorosporium consanguineumwas studied. Primary buds developed through expansion of all layers of the mother-cell wall. Subsequent buds arose through expansion of wall material which originated beneath, and protruded through, the outer layers of the mother-cell wall. This material was interpreted as the mother-cell septum formed during the previous budding process. Successive budding resulted in the formation of annellations at the apex of the mother cell. Septation was initiated by centripetal invagination of the plasmalemma at the junction of the mother and bud cells in which a double septum was formed prior to abscission. Our observations are compared with those reported for other yeastlike fungi and yeasts.

摘要:

SUMMARYIncubation of spores ofGigaspora margaritaon agar medium containing activated charcoal resulted in an increased rate of hyphal growth. Circular patterns simulated by hyphal growth from groups of centrally plated spores following germination permitted assessment of“colony”diam. Pretreatment of spores or water with activated charcoal did not enhance fungal growth. These results suggest that an inhibitor of fungal growth is produced or released during and/or after germination.

摘要:

SUMMARYCrystals at the surface of zygophores and sporangiophores ofMucor mucedowere investigated by electron microscopy, X-ray crystallography and chemical methods. Crystals on sporangiophores are spines, whereas those on zygophores have a tetragonal shape. Both types consist of calcium oxalate dihydrate (weddellite). Evidence is presented suggesting that the crystals are firmly anchored in, and in many cases are partly covered by, cell wall material.
