“…There have been several reports on the isolation of P. terrestris in Europe, North America, New Zealand, Jamaica, Panama, and Japan (Domsh et al 1993). The species was isolated from cultivated soil (Robison 1970), forest soil (Hammill 1970) and arable soil, and decaying stems and plant leaves (Badurova and Badura 1967;Ellis 1971;Matsushima 1975). These reports indicate that P. terrestris is distributed widely in nature.…”

Taxonomy and secondary metabolites of Pseudobotrytis sp. FKA-25

et al. 2004

Fungal strain FKA-25, isolated from forest soil collected on Yakushima Island, Kagoshima Prefecture, Japan, was assigned to genus Pseudobotrytis based on its morphological characteristics. Conidiophores were erect, slightly swollen at the end of the tip, and gave rise to umbellate conidiogenous cells that were in an expanded denticulate portion at the end and formed ellipsoidal to clavate conidia in sympodial succession. Identification as species P. terrestris was made on the basis of the character of 1-septate conidium. Although no secondary metabolites have been reported from the genus Pseudobotrytis, four secondary metabolite compounds (designated A to D) were isolated from the culture broth of strain FKA-25. Compounds B to D have been reported previously as FK-17-p2a, lunatinin, and 3,4-dihydro-3,4,8-trihydroxy-1(2H)-naphthalenone, respectively. Compound A was designated sespendole and possessed a novel indole-sesquiterpene skeleton.

Heat tolerant fungi and applied research: Addition to the previously treated group of strictly thermotolerant species

Heat tolerant fungi are organisms that may perform bioconversion processes and produce industrially important metabolites. They may either be obligate thermophiles or simple thermotolerants. The present document is the continuation of a critical note on thermotolerant fungi erroneously reported in the literature as possessing thermophilic attributes. Fifty strictly thermotolerant taxa are here considered. Some of their binomials have only recently been introduced in the scientific literature. The reported thermotolerant species are grouped according to broad taxonomic categories. The nomenclature of zygomycetous taxa and anamorphic fungi is straightforward, as usually only one binomial is available or only one state is produced in culture respectively. For Ascomycetes regularly producing in culture a conidial state, the name of the sexual state (teleomorph) should be used to designate the organism even when a binomial is available for the anamorph; this prevents the practice of interchangeably using the name of either states of the same fungus. When ascomycetous taxa produce the anamorph regularly and the teleomorph only under specific cultural conditions, the name of the anamorph could be preferentially selected. The goal is to introduce uniformity in name citations of fungi, particularly in the literature of applied research. Each species is reported under its taxonomically correct name, either the original binomial or the latest combined binomial after generic transfer(s). Known synonyms are also specified. Maximum efforts were undertaken to trace updated information on the taxonomic position of these fifty strict thermotolerant species. For each, information on the type material, morphological features distinguishing it from related members of the genus (and when necessary a generic taxonomic assessment) and, finally, salient ecological features including heat tolerance levels are given. For some information on their biotechnological use is also provided. Overall 86 strictly thermotolerant fungi are so far documented in the corresponding published and present contributions; however, this figure should not be regarded as exhaustive for the group. Among these 86 taxa ascomycetous fungi (46) presently outnumber anamorphic microfungi (28) but their relevant figures should be regarded as provisional. Only 12 zygomycetous species proved to be strict thermotolerants. Further cardinal temperature growth values established for these 86 thermotolerants disclose no pattern linked to their broad taxonomic categories. Standardized growth temperature curves at increments smaller than 5 °C have to be performed to assess conclusively variability in growth temperature relationships. Several heat tolerant fungi are widely used in industry; however, more research is needed to explore the applied potential of these particular organisms. An exhaustive document on the biodiversity of heat tolerant fungi also awaits production. It would be informative in relation to the global warming process of the earth.

“…During a review process of the manuscript, W. Gams (personal communication) suggested to propose the designation of neotype because the type material of Periconia felina Marchal is missing. We designate a collection CBS 147.81 as neotype of A. felinum agreeing with the morphology-based brief descriptions by Hammill (1970Hammill ( , 1981. It has been characterized by DNA sequence data (rDNA D1/D2 and ITS) in this study.…”
