Spadicoides palmicola sp.nov. is described from a senescent leaf of Licuala sp. collected in Brunei. It differs from other Spadicoides species in having verruculose conidiophores producing verrucose, obclavate, rostrate, multi-euseptate, versicoloured conidia. Spadicoides obclavata Kuthub. & Nawawi var. heterocolorata R.F. Castañeda, Guarro & Cano is considered distinct from Spadicoides obclavata, and Spadicoides heterocolorata comb.nov. is proposed.Key words: Hyphomycetes, Licuala, palm fungi, systematics, tropical fungi.

SynopsisIsolates of the tropical fungus Crinipellis perniciosa obtained from cocoa and lianas in Ecuador were grown on media ranging from −0.45 MPa to −9.0 MPa water potential and their responses compared to those of other agarics and Xylaria species isolated from cocoa. Antagonism between mycelia of C. perniciosa and these isolates was also assessed over the same range of water potentials. It is hypothesised that C. perniciosa and other canopy inhabiting fungi of tropical forests are adapted to water stress, but are not competitive with fungi which colonise later, following litterfall, from lower litter and soil horizons, where water availability is higher. Xylaria spp. proved to be aggressive antagonists of C. perniciosa over a range of water potentials.

During the course of recent researches into the nature of parasitic fungi, my attention was arrested for some time by several forms of epiphytal growths which occupy a sort of half-way position between the more pronounced endophyllous parasites, and those fungi which cannot he looked upon as requiring more than a hold-fast or shelter from their hosts. Among these are the Meliolas , group established by Fries in 1825 to receive certain tropical fungi. In the 'Annales des Sciences Naturelles' for 1851 is a memoir by Bornet on the species constituting the genus Meliola , in which the characters of these remarkable epiphytes are enumerated and examined, and a classification of the known forms proposed: this paper is a standing authority on the subject, and I shall have occasion to refer to it at intervals subsequently, partly to confirm some of Bornet’s work, partly to add new observations and correct older views as to the nature or significance of various points. The Meliolas are minute epiphyllous fungi, belonging to the the Pyrenomycetes , deep-brown or black mycelium of which appears as sooty patches on many and various plants in the tropics, and presents, roughly, a similar appearance to the masses of Capnodium or Fumago sometimes observed in European woods on the leaves of living plants.

Napocor Power Barge 103 was dislodged from its moorings and then slammed onto the rocky shoreline of Barangay Botongon when Typhoon Yolanda made a landfall in northern Iloilo on November 8, 2013. The oil spilled contaminated about a kilometre of Estancia's coastline and partly that of neighbouring town of Batad in Northern Iloilo, Western Visayas, Philippines. The present study aimed to isolate and evaluate hydrocarbon-degrading (singly or in combination) abillities of indigenous fungal flora from oil contaminated beach and mangrove soils in these areas. Results showed a total of twenty genera of marine-derived fungi were isolated. These genera included Acremonium, Aspergillus, Cladosporium, Curvularia, Monilia, Paecilomyces, Penicillium, Trichoderma, Verticillium and Yeast. Among the species, Aspergillus fumigatus obtained the highest frequency of occurrence (43.06%). Penicillium sp1 (EB331) got the highest value for individual category on TPH (64.70%) and PAH (43.42%) degradation. The consortium of Aspergillus fumigatus and Paecilomyces sp1, A+D obtained the highest values of 69.38% and 66.59% on the degradation of TPH and PAH with the increased efficacy of 13.61% and 42.41% on two species consortia. Moreover, the consortium composed of Aspergillus fumigatus, Aspergillus cf. repens and Paecilomyces sp1, A+B+D also were the best degraders of TPH and PAH with the values of 67.87% and 66.95% and increased efficacy of . 13.33% and 47.10%, respectively.Aspergillus cf. repens (BB231) got the highest value (81.98%) on the degradation of alkanes. The consortium of Aspergillus fumigatus and A. niger, A+C were the best alkane degraders at 77.93%with increased efficacy of 8.0%. Finally, the consortium of Aspergillus niger, Paeclomyces sp1 and Penicillium sp1, C+D+E recorded the highest value at 76.99% on the degradation of total alkanes with increased efficacy of 2.20%. This study has demonstrated the hydrocarbon-biodegradtion potential of tropical fungi isolated from oil contaminated habitats useful for future bioremediation activities.

ABSTRACT Polyketides draw much attention because of their potential use in pharmaceutical and biotechnological applications. This study identifies an abundant pool of polyketide synthase (PKS) genes from local isolates of tropical fungi found in Thailand in three different ecological niches: insect pathogens, marine inhabitants, and lichen mutualists. We detected 149 PKS genes from 48 fungi using PCR with PKS-specific degenerate primers. We identified and classified 283 additional PKS genes from 13 fungal genomes. Phylogenetic analysis of all these PKS sequences the comprising ketosynthase (KS) conserved region and the KS-acyltransferase interdomain region yielded results very similar to those for phylogenies of the KS domain and suggested a number of remarkable points. (i) Twelve PKS genes amplified from 12 different insect-pathogenic fungi form a tight cluster, although along with two PKS genes extracted from genomes of Aspergillus niger and Aspergillus terreus, in reducing clade III. Some of these insect-specific fungal PKSs are nearly identical. (ii) We identified 38 new PKS-nonribosomal peptide synthetase hybrid genes in reducing clade II. (iii) Four distinct clades were discovered with more than 75% bootstrap support. We propose to designate the novel clade D1 with 100% bootstrap support “reducing clade V.” The newly cloned PKS genes from these tropical fungi should provide useful and diverse genetic resources for future research on the characterization of polyketide compounds synthesized by these enzymes.
