Abstract:
Pleomorphic conidiogenesis was examined in four strains of Knufia cryptophialidica Hutchison & Untereiner in culture. The ex-type strain (DAOM 216555) was the most plastic, exhibiting various patterns of conidiogenesis, and was the only strain that produced phialides, that is, the most important diagnostic structure of the genus, although many of these phialides were aberrant and produced abnormally swollen conidia that appeared to lack cytoplasm. Subsequently, hyphae emerged from the aberrant phialides and some of these hyphae later disarticulated to form thallic-arthric conidia. The ex-t

Abstract:
Abstract We investigated the molecular organization of the region of Aspergillus nidulans chromosome I containing yA, a gene encoding the developmentally regulated enzyme conidial laccase. DNA fragments were identified that complemented the yA2 mutation and were shown to correspond to yA by genetic mapping and gene disruption experiments. The molecular map of the region was oriented to the genetic map by testing DNA fragments for their ability to complement a mutation in the tightly linked adE gene. The yA gene codes for a 2200 nucleotide mRNA that is present at low levels in vegetative cells

Abstract:
The present work aimed to isolate and characterize native strains of Trichoderma from Tungurahua, Ecuador. Four methods were used for isolation, the serial dilutions from soil samples being the one that allowed the most significant amount of Trichoderma isolates to be obtained. The diameter of the hyphae, the diameter of the conidia, and the length of the phialides were very similar among the four Trichoderma isolates. The conidiophores were branched with a dry appearance, ellipsoidal to spherical shape. The walls of the conidia were smooth. The conidia were colorless to green. Bottle-shaped p

Abstract:
A new species, Harposporium thaumasium X. Li et K.Q. Zhang, was isolated from forest soil in Yunnan, China. This species produces small, curved conidia, singly or in groups, from globose or ellipsoid phialides. Unlike other known Harposporium, this species produced novel arthroconidia that did not disarticulate at septa but germinated to produce typical phialides and infective conidia. Solitary or catenulate chlamydospores were also produced within infected nematodes and in pure culture. Narrowly elliptical to D-shaped accessory conidia were produced, only on potato dextrose agar and dextrose

Abstract:
Unlike most phialide-producing fungi that liberate a multiplicity of conidia from each conidiogenous cell, only single conidia are formed on phialide-like conidiogenous cells in Aphanocladium, Verticimonosporium, and some species of Sibirina. A group of isolates obtained from soil of native Artemisia tridentata (sagebrush) grassland in Wyoming and from desert soil in Iraq is compared with these genera and classified as a fourth genus, Stanjemonium, honouring Stanley J.

The genus Trichoderma Pers.:Fr. is defined to include anamorphs of Hypocrea, previously placed in Gliocladium and Verticillium, having elongate phialides and irregularly branched conidiophores. A sectional classification is proposed for Trichoderma recognizing the following five sections: section Trichoderma, section Longibrachiatum Bissett, section Saturnisporum Doi et al., section Pachybasium (Sacc.) stat.nov., and section Hypocreanum sect.nov. Trichoderma lactea sp.nov. is described, typifying section Hypocreanum. The species in section Trichoderma have narrow and flexuous conidiophores and

Abstract:
A new species, Ovicillium sinense, which was isolated from an infected pupa, is introduced. Morphological comparisons with extant species and DNA-based phylogenies from analysis of a multigene dataset of combined ITS, LSU and TEF sequence data support the establishment of the new species. It differs from other species by its phialides that are attenuated from the middle to the apex, the conidia aggregated in large globose to subglobose heads, and having shorter phialides and smaller conidia.

ABSTRACT The soil-borne fungus Fusarium oxysporum causes vascular wilt of a wide variety of plant species. F. oxysporum produces three kinds of asexual spores, macroconidia, microconidia, and chlamydospores. Falcate macroconidia are formed generally from terminal phialides on conidiophores and rarely from intercalary phialides on hyphae. Ellipsoidal microconidia are formed from intercalary phialides on hyphae. Globose chlamydospores with thick walls are developed by the modification of hyphal and conidial cells. Here we describe FoSTUA of F. oxysporum, which differentially regulates the develo

Abstract:
Aspergillus are ubiquitous molds that grow quickly, forming fluffy colonies in culture. Under microscopic examination an erect conidiophore has a swollen vesicle covered with phialides, which give rise to conidia. In tissue, hyphae predominate. The most common pathogen is Aspergillus fumigatus. Other pathogenic species include Aspergillus flavus, Aspergillus terreus, Aspergillus niger, Aspergillus ustus, and Aspergillus nidulans. There are increasing reports of other rare species causing infection.

Abstract:
Abstract Hyalohyphomycoses refer to human infections caused by soil-dwelling and plant saprophytic moulds (Ajello, 1986). Hyalohyphomycosis encompasses a loose artificial classification system since it does not refer to a specific taxonomic classification (Rippon, 1988a). Agents of hyalohyphomycosis include nonmelanin-producing, nondematiaceous moulds (Anaissie et al, 1989) whose typical appearance in histopathologic sections consists of colorless, hyaline, or light-colored septate hyphae. These hyphae are either branched or unbranched, and occasionally they are toruloid (Ajello, 1986; Anaissi
