Dothideomycetes comprise a highly diverse range of fungi characterized mainly by asci with two wall layers (bitunicate asci) and often with fissitunicate dehiscence. Many species are saprobes, with many asexual states comprising important plant pathogens. They are also endophytes, epiphytes, fungicolous, lichenized, or lichenicolous fungi. They occur in terrestrial, freshwater and marine habitats in almost every part of the world. We accept 105 families in Dothideomycetes with the new families Anteagloniaceae, Bambusicolaceae, Biatriosporaceae, Lichenoconiaceae, Muyocopronaceae, Paranectriellaceae, Roussoellaceae, Salsugineaceae, Seynesiopeltidaceae and Thyridariaceae introduced in this paper. Each family is provided with a description and notes, including asexual and asexual states, and if more than one genus is included, the type genus is also characterized. Each family is provided with at least one figure-plate, usually illustrating the type genus, a list of accepted genera, including asexual genera, and a key to these genera. A phylogenetic tree based on four gene combined analysis add support for 64 of the families and 22 orders, including the novel orders, Dyfrolomycetales, Lichenoconiales, Lichenotheliales, Monoblastiales, Natipusillales, Phaeotrichales and Strigulales. The paper is expected to provide a working document on Dothideomycetes which can be modified as new data comes to light. It is hoped that by illustrating types we provide stimulation and interest so that more work is carried out in this remarkable group of fungi.

Outline of Fungi and fungus-like taxa

Research on the mechanisms employed by the biocontrol agent Trichoderma virens to suppress cotton (Gossypium hirsutum) seedling disease incited by Rhizoctonia solani has shown that mycoparasitism and antibiotic production are not major contributors to successful biological control. In this study, we examined the possibility that seed treatment with T. virens stimulates defense responses, as indicated by the synthesis of terpenoids in cotton roots. We also examined the role of these terpenoid compounds in disease control. Analysis of extracts of cotton roots and hypocotyls grown from T. virens-treated seed showed that terpenoid synthesis and peroxidase activity were increased in the roots of treated plants, but not in the hypocotyls of these plants or in the untreated controls. Bioassay of the terpenoids for toxicity to R. solani showed that the pathway intermediates desoxyhemigossypol (dHG) and hemigossypol (HG) were strongly inhibitory to the pathogen, while the final product gossypol (G) was toxic only at a much higher concentration. Strains of T. virens and T. koningii were much more resistant to HG than was R. solani, and they thoroughly colonized the cotton roots. A comparison of biocontrol efficacy and induction of terpenoid synthesis in cotton roots by strains of T. virens, T. koningii, T. harzianum, and protoplast fusants indicated that there was a strong correlation (+0.89) between these two phenomena. It, therefore, appears that induction of defense response, particularly terpenoid synthesis, in cotton roots by T. virens may be an important mechanism in the biological control by this fungus of R. solani-incited cotton seedling disease.

The current study extends our knowledge of the biogeography of subtropical mangrove fungi from the Red Sea, which has not been well explored. Diversity of marine fungi in Red Sea mangroves in Egypt was assessed, and fungi dominating the communities were recorded and compared with those from other mangroves in subtropical and tropical regions. Intertidal decayed mangrove wood samples were collected from six mangrove stands located on the Red Sea coast in Egypt. Thirty-nine fungal species were identified on decayed wood of Avicennia marina. Of these, 19 are new records for Egypt and the Red Sea. The most frequent fungus was Swampomyces armeniacus. Other common fungi include: Hypoxylon sp., Lineolata rhizophorae, Kallichroma tethys, Swampomyces aegyptiacus and Lulworthia grandispora. Common fungi in the northern sites were different from those recorded from southern sites. Six fungi were recorded on Rhizophora mucronata prop roots for the first time in Red Sea mangroves. The diversity of fungi recorded in Red Sea mangroves is comparable to that recorded from subtropical mangroves, and lower than that recorded from tropical mangroves.

Abstract This study extends our knowledge of the diversity of marine fungi from Saudi Arabia, which is virtually unknown. Thirty-seven fungi (28 ascomycetes, eight asexual fungi, and one basidiomycete) were recorded from 457 samples of driftwood and intertidal decayed wood of Avicennia marina collected from three sites along the Red Sea coast of Saudi Arabia. The three sites include two mangrove sites, namely: Yanbu and Farasan Island, while the third site is a sandy shore nearby Yanbu city. Thirty-one fungi were new records for Saudi Arabia. Swampomyces triseptatus is the only species common to the three sites. The recorded marine fungi were latitudinally distributed with fungi recorded from Yanbu (subtropical site) largely different from those at Farasan Island mangrove (tropical site) with only six common fungi recorded. Amarenographium solium was the most common fungus at Yanbu mangrove, while Lineolata rhizophorae dominated the fungal community at Farasan Island mangrove. Swampomyces armeniacus was commonly recorded at the two mangrove sites. Torpedospora radiata was the most common species recorded from driftwood samples collected at Yanbu beach. A new collection of Diatrypasimilis australiensis enabled us to make a detailed morphological study of the fungus. Mycelia with chlamydospores were isolated from the samples and subsequently sequenced, and they grouped in the Corollospora clade with various degrees of confidence, but did not sporulate on natural material or in culture.

Vehicle counting is considered one of the most important applications in traffic control and management. To count vehicles, synchronous vehicle detection and tracking should be carried out. Recently, detection via deep neural networks (DNN) has achieved good performance. However, exploiting the DNN efficiently for vehicle counting is still challenging. In this paper, an efficient approach for vehicle counting employing DNN and KLT tracker is proposed. To decrease the time complexity, vehicles are detected via DNN every N-frames, N=15 for example. Trajectories are extracted by tracking corner points through the N-frames. Then an efficient algorithm is introduced to assign unique vehicle labels to their corresponding trajectories. The proposed results, performed on diverse vehicle videos, show that vehicles are accurately tracked and counted whatever they are detected one or more times by the DNN.

Accurate Vehicle Counting Approach Based on Deep Neural Networks

Being trajectory tracking key for safe mobile robot navigation, Fuzzy Logic (FL) has been useful in tackling uncertainty and imprecision to realize robust and smooth trajectory tracking. In this paper, we present the Z-number based Fuzzy Logic control for trajectory tracking of differential wheeled mobile robots. The unique point of our approach lies in the ability to encode constraint and reliability in multi-input and multi-output rules, whose antecedent universe considers only the instantaneous measurements of distance and the orientation gaps, and whose consequent universe is computed by the interpolative reasoning and the graded mean integration approach. As a consequence, not only our approach avoids the complexity of encoding error gradients, but also is advantageous to model versatile control rules able to cope with missing observations and noisy inducements on actuators. Our experiments using both physics-based simulations and real-world tests based on a Pioneer 3DX robot architecture have elucidated the superior efficacy and the feasibility of the proposed controller regarding accuracy, robustness, and smoothness compared to other well-known related frameworks such as Fuzzy Logic Type 1, Fuzzy Logic Type 2 and Fuzzy Logic with PID. Our results provide unique insights to realize generalizable algorithms aided by FL and Z-number towards robust trajectory tracking.
