1. Campylospora leptosoma sp. nov. and characteristics of Campylospora spp., based on morphology and on ITS sequences

Authors: Marvanová L, Laichmanová M

Recieved: 01 February 2014, Accepted: 24 February 2014, Published: 06 March 2014

Campylospora leptosoma is described as new species. C. filicladia and C. parvula are lectotypified, epitypes of C. filicladia and C. parvula are established. ITS–based phylogenetic analysis of 18 isolates of four species of Campylospora confirms monophyly of the genus. Delimitation of C. chaetocladia, C. filicladia and C. parvula based on morphology is supported by phylogenetic analysis. C. leptosoma, although morphologically homogeneous, falls into two groups: one forms a well supported sister clade of C. parvula, the other an unsupported sister clade of C. chaetocladia.

Keywords: aquatic hyphomycetes – Campylospora chaetocladia – C. filicladia – C. parvula – epitypes – lectotypes

In terms of their flora and fauna, tropical forests are generally reported to be characterized by higher species diversity than temperate forests. Can this also be true for microorganisms such as myxomycetes? In the present study, three lowland tropical forests in the Philippines and three mid-latitude temperate forests in north central Arkansas in the United States were surveyed for myxomycetes with the moist chamber technique as it applies to these organisms. Results indicated that more species of myxomycetes were associated with samples of aerial litter (dead but still attached plant parts), forest floor litter and woody twigs collected in Arkansas than for those collected in the Philippines. A higher value for taxonomic diversity also was noted for the temperate forests. However, 19 species listed herein are new records for the Philippines. In the present study, a comparison of the taxonomic diversity of myxomycetes in relation to the number of moist chamber replications was carried out, and this showed that a difference of as many as eight species could occur between what was recorded from a single culture and a series of three cultures prepared from the same sample. Clearly, many of these species could be missed if only a single culture is prepared for a particular sample.

9. Pyrenophora

Authors: Ariyawansa HA, Kang JC, Alias SA, Chukeatirote E, Hyde KD

Recieved: 09 March 2014, Accepted: 05 April 2014, Published: 20 April 2014

This is the first in a series of papers in which we revisit genera of fungi to provide baseline data for future study. In this article we examine the genus Pyrenophora and provide details of morphology, phylogeny and the current status of species. Pyrenophora is a genus of saprobic and plant pathogenic fungi with a worldwide distribution, commonly associated with leaves, wood, cereals and other grasses. A phylogeny for Pyrenophora (sexual state of Drechslera) and allied genera is presented based on analysis of ITS, GPDH, RPB2, nrSSU and nrLSU DNA sequence datasets. Pyrenophora is a monophyletic genus in Pleosporaceae. Pyrenophora sexual states cluster with their expected Drechslera asexual states. As a genus can now only have one name we synonymise Drechslera underPyrenophora.

Keywords: GPDH – RPB2 – Epitypification – Nomenclature

 

10. Revealing the antimicrobial and enzymatic potentials of culturable fungal endophytes from tropical pitcher plants (Nepenthes spp.)

Authors: Lee JM, Tan WS, Ting ASY

Recieved: 28 January 2014, Accepted: 24 March 2014, Published: 21 April 2014

In recent years, fungal endophytes from diverse host species have been extensively studied for valuable compounds (enzymes, antimicrobial compounds). Investigations on fungal endophytes from tropical Nepenthes spp. are however limited, despite hosting a wide range of macro- and microorganisms. In this study, we explored fungal endophytes from N. ampullaria and N. mirabilis for enzymatic and antimicrobial potential. A total of 26 isolates were obtained and they demonstrated a variety of enzymatic activities, mostly producing cellulase, chitinase, lipase and L- asparaginase. These endophytes also have antifungal activity. Sequencing results on 12 selected isolates revealed a diverse endophytic community, comprising mainly of the species complex of Colletotrichum gloeosporioides (and its teleomorph Glomerella) (3 isolates), Phomopsis sp.(2 isolates), Trichoderma asperellum, Penicillium simplicissimum and Aspergillus terreus. Several uncommon species were also revealed-Lasiodiplodia, Isaria, Sarcosomataceae and a yeast-like fungi Meyerozyma guilliermondii. We revealed the diversity and the novel profiling of enzymatic and antimicrobial potential of endophytes from Nepenthes.

Keywords: antibacterial – antifungal – enzymes – Nepenthes ampullaria – Nepenthes mirabilis
