We describe Diploschistes stereocaulorum as a new species of lichenized fungi growing on phyllocladia and stalks of Stereocaulon in the Pacific Northwest of North America. The larger ascospores of this species, the absence of a noticeable thallus, and the ITS barcode locus distinguish it from D. muscorum, which has been reported as growing on Stereocaulon, but has smaller ascospores and a distinct thallus. In phylogenetic reconstruction, the new species is sister to D. diacapsis, albeit without support.
我们描述了 Diploschistes stereocaulorum，它是生长在北美洲西北太平洋地区 Stereocaulon 植物叶柄和茎秆上的地衣化真菌新物种。该物种较大的腹孢子、没有明显的菌柄以及 ITS 条形码位点将其与 D. muscorum 区分开来，后者曾被报道生长在 Stereocaulon 上，但其腹孢子较小，且有明显的菌柄。在系统发育重建中，该新种是 D. diacapsis 的姊妹种，但没有得到支持。

We describe 14 new lichen species in the family Graphidaceae, mainly from the Amazon basin: Acanthothecis aggregata, Allographa ancelina, A. apicalinspersa, Chapsa constrictospora, C. diorygmoides, C. lichexanthonica, Clandestinotrema caloplacosporum, Diorygma defectoisidiatum, D. gyrosum, D. lichexanthonicum, D. norsubmuriforme, D. salxanthonicum, D. toensbergianum, and Ocellularia flavoradiata. For each species, it is indicated where and how it would key out in a recent identification key. Two of the Diorygma species are sterile and were assigned to this genus by sequencing the mtSSU gene. Five additional species are new to Brazil and 27 others, including some Gomphillaceae, are new state records.

The new combination Xenolecia masafuerensis is made for Lecanora masafuerensis, a lichen species known from only two localities on Isla Alejandro Selkirk in the Juan Fernández archipelago, Chile. The species is fully described and illustrated and shown to be morphologically and chemically distinct from the similar X. spadicomma, which is known only from Chile and the Falkland Islands. The typification of X. masafuerensis and its distribution on the islands are also discussed.

Recent lichenological fieldwork in the Czech Republic resulted in the discovery of two previously unrecognized entities in the genus Psilolechia which are described below as new species: the saxicolous P. cretacea and the lignicolous P. torii. Both taxa regularly produce a hyphomycetous anamorph in the form of erect, elongate conidiogenous cells on the thallus surface, and both contain unidentified specific secondary metabolites. The placement of the two new species within the genus is primarily based on morphology and chemistry. In addition, three barcodes were received for P. cretacea (ITS, mtSSU) and P. torii (ITS). A key to the five species of Psilolechia currently known from Europe is included.
最近在捷克共和国进行的地衣学实地考察发现了 Psilolechia 属中两个以前未被发现的实体，现将其描述为新种：木质化的 P. cretacea 和木质化的 P. torii。这两个类群都会在菌体表面以直立、拉长的分生孢子细胞的形式产生一种拟真菌，并且都含有未确定的特定次级代谢产物。将这两个新物种归入该属的主要依据是形态学和化学成分。此外，还收到了 P. cretacea（ITS，mtSSU）和 P. torii（ITS）的三个条形码。目前已知的欧洲 Psilolechia 的五个种的检索表也包括在内。

The genus Parvoplaca is extended with four new species: P. candanii from Antarctica, P. lamprocarpa from Alaska, and P. macroborealis and P. tenebrosa from Oregon. Collections identified as P. tiroliensis are shown to form two independent clades when DNA was analyzed, but it is currently not clear which clade represents the species in a strict sense. Parvoplaca athallina has been considered an Antarctic species, but according to our analyses, the species is shown to be bipolar occurring also in northern Europe, Greenland, Alaska and in California.
Parvoplaca 属增加了四个新种：P.macroborealis和P. tenebrosa。在对 DNA 进行分析时，被鉴定为 P. tiroliensis 的采集物形成了两个独立的支系，但目前还不清楚哪个支系严格意义上代表了该物种。Parvoplaca athallina 一直被认为是南极物种，但根据我们的分析，该物种是两极物种，也出现在北欧、格陵兰岛、阿拉斯加和加利福尼亚。

Based on resampling the type locality and surrounding regions, along with phylogenetic analysis of molecular data, we elevate Stereocaulon sasakii var. tomentosoides to the species level, while we treat S. sasakii var. simplex as an environmental modification of S. tomentosoides. We found no phylogenetic evidence that any variety of S. sasakii occurs in North America, so we suggest that the species be removed from the North American list and its North American varieties transferred to S. tomentosoides. Stereocaulon tomentosoides is so far confirmed only from the Pacific Northwest of North America. Furthermore, it is largely allopatric with S. tomentosum, apart from a small region of overlap in northern Idaho and western Montana. While S. tomentosum always contains stictic acid and never lobaric acid as secondary metabolites, S. tomentosoides differs in having a predominant chemotype of lobaric acid as the major substance, with an infrequent chemotype containing both lobaric and stictic acids. While S. tomentosoides usually contains Nostoc in the cephalodia, occasional individuals, especially from old mossy lava flows, contain Stigonema; one specimen was found with both kinds of cephalodia on a single thallus. Phylogenetic analysis of these species and other close relatives revealed an additional species described here, S. cyaneum, so far known only from the Great Lakes region of the United States and Canada and separated from S. tomentosum by its bluish coloration, wet or dry
基于对模式标本产地及周边地区的重新取样，以及对分子数据的系统发育分析，我们将Stereocaulon sasakii var.S. sasakii 的任何变种出现在北美，因此我们建议将该种从北美名录中删除，并将其北美变种归入 S. tomentosoides。迄今为止，Stereocaulon tomentosoides 只被证实产于北美洲的西北太平洋地区。此外，除了爱达荷州北部和蒙大拿州西部的一小片重叠区域外，它与 S. tomentosum 大体上是同域植物。S. tomentosoides 的不同之处在于，它的主要化学类型是萝蔔酸，但同时含有萝蔔酸和石杉酸的化学类型并不多见。S.tomentosoides的头状花序中通常含有Nostoc，但偶尔也会含有Stigonema，尤其是来自古老的长满苔藓的熔岩流中的个体；在一个标本中发现了两种头状花序。对这些物种和其他近亲进行系统发育分析后，发现了这里描述的另一个物种--S. cyaneum，到目前为止，人们只知道它产于美国和加拿大的大湖区。

The species described as Bacidia genuensis is transferred here to Bacidina as B. genuensis (Ramalinaceae, Lecanorales, lichenized Ascomycota). An updated morphological description is provided. The species is characterized by mostly blackish apothecia on a thick, microsquamulose thallus, a crystal-inspersed proper exciple that is mostly prosoplechtenchymatous, an ascus with a wide and dome-shaped axial body and an expanded c-layer (resulting in a thin, amyloid d-layer), a blue-green pigment in the epihymenium, proper exciple, and pycnidial wall, and an orange-brown, K+ intensifying pigment in the hypothecium and sometimes proper exciple. This combination of characters sets the species apart from its potentially close relatives Bacidina egenula and B. indigens, as well as the superficially similar, but more distantly related, Toniniopsis bagliettoana. Bacidina genuensis is currently known from a few sites in northern Italy, where it inhabits weathered and apparently shaded mortar of masonry.
Genensis (Ramalinaceae, Lecanorales, lichenized Ascomycota) 归入 Bacidina。提供了最新的形态描述。该物种的特征是：厚厚的微鳞片状菌苔上的外植体大多呈黑色，晶体状的正外植体大多为前胸腺体，腹膜具有宽大的圆顶形轴心体和膨大的 c 层（形成一层薄的淀粉样 d 层），外植体、正外植体和菌丝壁中含有蓝绿色色素，下表皮层和有时正外植体中含有橙棕色的 K+ 增强色素。这一特征组合使该物种有别于其潜在近亲 Bacidina egenula 和 B. indigens，以及表面相似但亲缘关系更远的 Toniniopsis bagliettoana。目前已知的 Bacidina genuensis 来自意大利北部的几个地点，栖息在风化和明显荫蔽的砖石灰浆中。

A lichenicolous fungus forming large black, vertically elongate, campylidia-like conidiomata on the thallus of Ochrolechia was recently collected in Austria, Mexico and the USA. The conidia are so remarkable in being multiappendiculate that initially no existing fungal genera appeared to be suitable for its description. Nevertheless, molecular phylogenetic analyses of nuITS and nuLSU sequences recovered the species within the genus Mycocalicium. To date, no species of Mycocaliciales has been reported producing appendiculate conidia. The species is described as new M. campylidiophorum. The new species was also discovered in the type specimen of Opegrapha chionographa that was collected in Colombia 163 years ago. This discovery led us to revise O. chionographa, originally described as a lichen, and clarify that in fact the name applies to a lichenicolous fungus based on type material that is an admixture of M. campylidiophorum, an Ochrolechia and an Opegrapha species. The name is shown to apply to the Opegrapha species and lectotypified as such. Opegrapha blakii is treated as synonym of O. chionographa.
最近在奥地利、墨西哥和美国收集到了一种地衣真菌，它在 Ochrolechia 的菌体上形成大型黑色、垂直拉长、类似钟乳体的分生孢子器。这种分生孢子体非常显著，呈多附肢状，因此最初似乎没有现存的真菌属适合描述这种分生孢子体。然而，通过对 nuITS 和 nuLSU 序列进行分子系统进化分析，发现该物种属于 Mycocalicium 属。迄今为止，还没有报道过产生附属分生孢子的霉属菌种。该物种被描述为新的 M. campylidiophorum。该新种也是在 163 年前于哥伦比亚采集的 Opegrapha chionographa 的模式标本中发现的。这一发现促使我们修改了最初被描述为地衣的 O. chionographa，并澄清该名称实际上适用于一种地衣真菌，其模式标本是 M. campylidiophorum、Ochrolechia 和 Opegrapha 的混合物。该名称被证明适用于 Opegrapha 种，并按此进行了标本分型。Opegrapha blakii 被视为 O. chionographa 的异名。
