Murinicarpus subadustus described from China is the only species of the genus Murinicarpus ( Polyporales , Basidiomycota ). There is no other report of this genus from any other country except China. Here, we report M. subadustus as a novelty to the macrofungal biota of India. This unique species is identified based on morphological features and nrDNA ITS-based phylogenetic analysis. A thorough macro- and microscopic characterisation along with field photographs, line drawings of microscopic structures and comparisons with morphologically and phylogenetically related taxa are provided.
中国描述的亚灰岩是灰岩属(多孔菌门,担子菌门)中唯一的一种。除中国外,其他任何国家都没有关于该属的报告。在这里,我们报道了印度大型真菌生物群中的一种新生物亚尘分枝杆菌。这一独特的物种是根据形态学特征和基于nrDNA ITS的系统发育分析确定的。提供了全面的宏观和微观特征,以及现场照片、微观结构的线条图以及与形态和系统发育相关分类群的比较。

Opportunistic and nosocomial human infections by various Candida species are of serious global health concern especially due to the spread of drug resistant strains and lack of treatment options. One of the main problems of bioprospecting for novel antimycotics is the rediscovery of already known molecules. To reduce the chances of such rediscoveries, one option is to search for unique metabolites from microbes of less studied and extreme habitats. Thirty-five fungal strains were isolated from solar salterns and the methanolic extracts of their culture supernatants were tested for the inhibition of human-pathogenic Candida albicans , C. dubliniensis , C. glabrata , C. lusitaniae , C. tropicalis , and two clinical isolates of C. auris . Of the fungi screened, two, viz. Curvularia nodosa and Fusarium cf. foetens , showed significant growth inhibition of all the Candida species. Although the effective molecules were not identified in this preliminary screening, it highlights the importance of bioprospecting fungi from extreme environments which have been neglected in the search for novel antibiotics.
各种念珠菌引起的机会性和医院内人类感染是严重的全球卫生问题,特别是由于耐药菌株的传播和缺乏治疗选择。生物勘探新型抗真菌药物的主要问题之一是重新发现已知分子。为了减少这种重新发现的机会,一种选择是从研究较少和极端栖息地的微生物中寻找独特的代谢物。从太阳盐中分离到35株真菌,对其培养上清液甲醇提取物对人致病性白色念珠菌、dubliniensis、C. glabrata、C. lusitaniae、C. tropicalis和2株临床分离的金黄色念珠菌进行了抑菌试验。在筛选的真菌中,两种真菌,即曲霉菌(Curvularia nodosa)和镰刀菌(Fusarium cff . foetens)对所有念珠菌都有明显的生长抑制作用。虽然在这次初步筛选中没有发现有效的分子,但它强调了在寻找新型抗生素时被忽视的极端环境中生物勘探真菌的重要性。

They are situated in the Bohemian Forest and several mountain ranges the and Eastern Carpathians. The elevation range of the records is 525–1200 m a.s.l. All records are from Abies alba , mostly branches attached to freshly fallen trunks and sticking out into the air.

Cadophora orchidicola , a root-associated asexual species, did not have a clear placement within the paraphyletic genus Cadophora because it was not represented by sequences derived from the type material . Based on four newly obtained molecular marker sequences from the ex-type strain, a new genus, Leptodophora , is proposed, typified with C. orchidicola , as well as new combinations for three recently described and closely related species. In addition, a new species, Collembolispora disimilis , is proposed for a fungus producing phialidic conidiogenous cells and previously treated as Cadophora sp.

“Old-growth forests” comprise habitats from untouched, primeval forests to partially man-influenced, near-natural forests. Some fungal species occur preferably in these forests with a high degree of naturalness. Occurrence data from Slovakia for five wood-inhabiting fungal species was processed. The numbers of known localities of these species in Slovakia range from 4 to 49. The five species prefer different stages of wood decay when producing fruitbodies. Records of the studied species indicate that Amylocystis lapponica and Ionomidotis irregularis occur only in old-growth forests, especially in the best-preserved virgin and natural ones, in Slovakia typically on wood of only one or two tree species. Antrodia labyrinthica occurs in natural and nearnatural forests, while the remaining two species can survive in managed forests with a natural tree composition, localised close to forests of higher naturalness (Skeletocutis odora) or even in more intensively managed forests with a small amount of decaying wood and parks (Yuchengia narymica). The substantial increase in the number of records of some species in Slovakia can be related to more intensive research in montane old-growth forests (e.g. Amylocystis lapponica) or probably to a massive spread of species (Yuchengia narymica), even in a wide elevation range.
“原始森林”包括从未受破坏的原始森林到部分受人类影响的接近自然的森林的栖息地。有些真菌种类更适合在这些高度自然的森林中生长。对斯洛伐克5种木质真菌的发生数据进行了处理。这些物种在斯洛伐克已知的分布地点从4个到49个不等。在产生子实体时,这五种植物喜欢不同的木材腐烂阶段。研究物种的记录表明,拉波尼支链霉菌和不规则支链霉菌只发生在原始森林中,特别是在斯洛伐克保存最好的原始森林和自然森林中,通常只在一种或两种树种的木材上。Antrodia labyrinthica发生在自然和nearnatural森林,而其余两个物种可以生存在森林管理自然树组成,局部接近高等自然森林(Skeletocutis odora),甚至更多的集中管理与少量的腐木森林和公园(Yuchengia narymica)。斯洛伐克某些物种记录数量的大幅增加可能与对山地原生林(如Amylocystis lapponica)进行了更深入的研究有关,也可能与物种(Yuchengia narymica)的大规模传播有关,即使在很宽的海拔范围内。

Disentangling the taxonomy of Octospora meslinii (Pezizales), a bryophilous ascomycete on Grimmia pulvinata. 对灰蝶上嗜苔藓子囊菌Meslini八孢菌(Pezizales)的分类学进行了研究。

The bryophilous ascomycete Octospora meslinii is a rarely reported species growing exclusively in cushions of the saxicolous moss Grimmia pulvinata. The taxon has been misunderstood in the past and hitherto reliably only reported from France and Germany. Many recent collections from Hungary have made it possible to get a better understanding of O. meslinii, which is comprehensively described and illustrated in this paper. Because of the lack of original material, we designate an illustration in the protologue as the lectotype and one of the recent collections as the epitype of this fungus. Octospora meslinii is compared with other species of Octospora growing in the same type of habitat or having similar ascospores. The most closely related species to O. meslinii is O. pseudoampezzana. Both share apothecia with blackish pigmentation, a unique feature compared to bryophilous Pezizales as a whole, ellipsoid ascospores ornamented with isolated warts, moss hosts in the family Grimmiaceae, and the infection inducing galls on the rhizoids. A phylogenetic analysis using the EF1 , LSU and SSU rDNA loci confirms our morphological findings showing that O. meslinii forms a monophyletic clade with O. pseudoampezzana, whereas other species with which O. meslinii was confused in the past, e.g. O. similis, are related only distantly.
嗜苔藓子囊菌Octopora meslinii是一种很少报道的物种,专门生长在沙苔Grimmia pulvinata的垫子上。该分类单元在过去一直被误解,迄今为止只可靠地从法国和德国报道。最近从匈牙利收集的许多藏品使人们有可能更好地了解O.meslinii,本文对其进行了全面的描述和说明。由于缺乏原始材料,我们在序言中指定了一幅插图作为选择型,并将最近收藏的一幅插图指定为这种真菌的表型。meslinii八孢菌与生长在相同类型栖息地或具有相似子囊孢子的其他八孢菌进行了比较。与墨氏O.meslinii亲缘关系最密切的物种是假ampezzana。与亲苔藓的Pezizales相比,两者都有黑色色素沉着的末端古猿,这是一个独特的特征,椭圆形子囊孢子装饰着孤立的疣,苔藓科中的苔藓宿主,以及根瘤上诱导感染的疣。使用EF1、LSU和SSU rDNA基因座进行的系统发育分析证实了我们的形态学发现,即梅氏O.meslinii与假ampezzana形成一个单系分支,而梅氏O.Mesliii过去与之混淆的其他物种,如相似O.similis,只存在远缘。

Triadelphia (Ascomycota, Microascales) is a genus encompassing pleomorphic dematiaceous micromycetes occurring sporadically on rotting wood and other plant material, infrequently also on other substrates. In this study, we document a second record of Triadelphia morgoensis, found on a twig of Populus nigra near Prague (Czech Republic), after its original description from decaying wood in Hungary. This fungus is characterised by the production of three types of conidia. The identification was achieved by a combination of morphological, physiological and genetic traits. The description of the fungus is emended, and its differentiation from similar species is discussed. Multigene phylogeny showed that T. morgoensis is most closely related to T. loudetiae and T. heterospora. The DNA data from three loci generated in this study (ITS, LSU, RPB2) will facilitate identification of the species in the future. Our results add to the knowledge on the ecology and phylogeny of this understudied fungus, for which neither living type material nor a molecular sequence has been preserved.
Triadelphia (Ascomycota, Microascales)是一个包含多形性囊状微菌的属,偶尔出现在腐烂的木材和其他植物材料上,也很少出现在其他基质上。在这项研究中,我们记录了在布拉格(捷克共和国)附近的黑胡杨(Populus nigra)树枝上发现的第二次记录,在匈牙利的腐烂木材中发现了它的原始描述。这种真菌的特点是产生三种类型的分生孢子。通过形态、生理和遗传性状的综合鉴定。对该真菌的描述进行了修订,并讨论了其与同类真菌的区别。多基因系统发育表明,morgoensis与T. loudetiae和T. heterospora亲缘关系最为密切。本研究生成的3个基因座(ITS, LSU, RPB2)的DNA数据将有助于今后对该物种的鉴定。我们的研究结果增加了对这种未被充分研究的真菌的生态学和系统发育的认识,因为它既没有保存活的类型材料也没有保存分子序列。
