SULCOPYRENULA,A NEW PYRENOCARPOUS LICHEN GENUS (PYRENULACEAE,LICHENIZED ASCOMYCOTA)

Sulcopyrenula H. Harada gen. nov. is described. It differs from other genera ofPyrenulaceae by having longitudinally sulcate spores. The genus is represented by two species: S. canellae-albae (Fée) H. Harada comb. nov. and S. staurospora (Tuck.) H. Harada comb. nov. Both species have been previously reported from N. and S. America, and the latter species is now reported from Asia.     

MYELOCONIS,A NEW GENUS OF PYRENOCARPOUS LICHENS FROM THE TROPICS

MyeloconisP. M. McCarthy & Elix gen. nov. is described from the Neotropics and the eastern Paleotropics. Four new species,M. erumpens, M. fecunda, M. guyanenisandM. parva, are recognized. The genus is characterized by a medulla containing previously unknown yellow or orange pigments and perithecioid ascomata with a dark, dense, almost pseudostromatal wall, a basally anastomosing, but otherwise free, hamathecium, uniformly thin-walled asci and elongate, muriform ascospores. While its affinities are uncertain, the ascomata and their contents suggest a rather close relationship withPorinaMüll. Arg. andClathroporinaMüll. Arg. (Trichotheliaceae).     

A NEW BYSSOID LICHEN GENUS FROM TASMANIA

The genusJarmania, based on the single speciesJ. tristis, is described. The new genus is characterized by a byssoid-leprose thallus, immarginate apothecia, asci of theBacidia-type, strongly anastomosing paraphyses and septate, acicular ascospores. The new species is corticolous and is known only from cool temperate rainforest in Tasmania. 1996 The British Lichen Society

中国鸡皮衣属地衣二新记录种*

中国鸡皮衣属Pertusaria DC.地衣迄今仅见零星报道,尚无专门研究;作者从形态学、解剖学、化学及地理学角度对藏于中国科学院微生物所菌物标本馆 (HMAS-L) 和荷兰CBS的标本室 (ABL) 的该属地衣标本进行了初步研究,发现了两个中国新记录种,现报道如下。 1无屑鸡皮衣 Pertusaria aberrans Müll. Arg., Bull. Herb.

中国地衣新记录属─小腊肠衣属(英文)

在进行《中国地衣志》的编写中,作者从采自我国新疆阿尔泰山哈纳斯湖附近的地衣标本中发现了北极小腊肠衣［Ｂｒｏｄｏａｏｒｏａｒｃｔｉｃａ（Ｋｒｏｇ）Ｇｏｗａｒｄ］（茶渍目,子囊菌门）。小腊肠衣属（ＢｒｏｄｏａＧｏｗａｒｄ）是中国新记录属,因而,也是中国地衣区系中已知的第２３４个属。本文对于该属、种在形态学、结构学、化学及地理分布等方面进行了描述与讨论。对于它和邻近属的区别也做了简要的对比。     

中国疱脐衣属的新种与新资料

本文报道了中国疱脐衣属四个新分类单位,其中包括三个新种:华东疱脐衣(Lasallia sinorientalis Wei),大理疱脐衣(L.daliensis Wei),苍山疱脐衣(L.caeonshanensis Wei)及东亚疱脐衣一新变种:樊净山变种(L.asiae-orientalis var.fanjingensis Wei)。此外,还从东亚疱脐衣的模式标本中首次发现了该种的子囊盘,并作了补充描述。作者认为,根据有关中国地衣区系的现有知识,迄今尚未发现分布于中国的疱脐衣(Lasallia pustulata(L.)Merat)。而华东疱脐衣可能是疱脐衣在亚洲的地理替代种。     

LECANORA PARAMERAE,A NEW LICHEN FROM SPAIN

Lecanora paramerae is described from Central-East Spain. At the only two known localities it grows on Juniperus thurifera trees in the ‘Serranía de Cuenca’ mountains. It is chemically characterized by the presence of 2′- O -methylperlatolic acid in addition to atranorin and psoromic acid. Anatomically, it can be recognized by the presence of large and irregular crystals in the amphithecium, a pulicaris -type epihymenium and broadly ellipsoid ascospores.     

GYALIDEA PRAETERMISSA,A NEW LICHEN FROM SWEDEN

The diminutive speciesGyalidea praetermissais described from Central Sweden. At the only known locality it grows on the sheltered and shaded vertical north side of a large boulder in an open pine forest. The species is mainly characterized by the 4–5-septate spores. 1996 The British Lichen Society     

中国果疣衣属地衣的研究

果疣衣属地衣系子囊菌门Ascomycota,子囊菌纲Ascomycetes,茶渍衣亚纲Lecanoromycetidae,鸡皮衣目Pertusariales,鸡皮衣科Pertusariaceae的成员。由于粉色果疣衣Varicellariarhodocarpa在中国的首次发现,使中国地衣区系中新增添了一个属:果疣衣属Varicellaria。该属迄今已知仅含三种,即粉芽果疣衣V.kemensis,八孢果疣衣V.carneonivea及粉色果疣衣V.rhodocarpa。果疣衣属为壳状地衣,地衣体微薄,膜质;子囊盘茶渍型,单个或数个聚生于瘤状果疣中;类侧丝多分枝并呈网状缠绕;子囊内含单孢或八孢;子囊孢子大型(长度为200~400mm),双胞,无色透明,椭圆形;孢子壁厚达27mm;与鸡皮衣属不同之处在于前者子囊内含双胞孢子,后者子囊内含单胞孢子。由于该属在中国是首次被发现,为了进一步的研究,文中还提供了该属迄今已知的全部三种的分种检索表。粉色果疣衣以其地衣体基本无粉芽和遇Pd呈负反应而区别于粉芽果疣衣,以子囊内含单孢而区别于八孢果疣衣。通过薄板层析法首次从该种髓部检测出茶渍衣酸。其地理成分为北极高山种,主要分布于欧洲的挪威、瑞典、芬兰、阿尔卑斯山脉,喀尔巴阡山脉、苏格兰以及北美洲;在亚洲迄今只见于日本与中国。     

中国砖孢发属地衣研究

简短回顾了砖孢发属地衣研究概况。在已知的8种亚洲砖孢发属地衣中,中国有七种,其中两种为台湾特有。根据150余份标本的形态与化学特征,承认中国大陆砖孢发属地衣5种,指出了个别异名,发现亚洲砖孢发(Okpogon asiaticus)存在两个化学型,提供了中国5种砖孢发地衣分布的新资料。研究结果表明,5种砖孢发地衣集中分布于我国云南、四川和西藏东部。作者认为中国西南地区是砖孢发属地衣在亚洲的一个分布中心。     

THELOPSIS FOVEOLATA,A NEW LICHEN FROM NORTHERN SPAIN

Thelopsis foveolataRenob. & Barreno sp. nov., is described from Northern Spain. It appears to be very rare and easily overlooked, but has a well-defined ecology. It grows on limestone within sciaphilous and humidity-loving communities, such asGyalectetum leucaspidisandPetractinetum hypoleucae. The pycnidia and conidiogenous cells are described and illustrated, this being the first detailed account of these structures in the genusThelopsis. 1996 The British Lichen Society     

PORINA RADICICOLA,A NEW LICHEN FROM WESTERN NORTH AMERICA

Porina radicicolasp. nov. is described from Washington, U.S.A. and British Columbia, Canada.     

BACIDIA CAESIOVIRENS,A NEW LICHEN SPECIES FROM WESTERN EUROPE

Bacidia caesiovirensS. Ekman & Holien sp. nov. is described from Norway, and the British Isles. It occurs on trunks of deciduous trees in coastal forests. This species is usually sterile and is characterized by its conspicuously blue-green, granular thallus, which contains a bluish, N+ purple pigment. It is closely related toB. biatorina(Körb.) Vain., but differs from this species in a number of features apart from thallus pigmentation: the thallus granules are smaller, the amount of hyphal projections from the surface of the thallus granules is larger, and the internal pigmentation of the apothecia is different.Bacidia auerswaldii(Hepp ex Stizenb.) Mig. has a similarly granular thallus but differs fromB. biatorinaandB. caesiovirensin having wide, fusiform spores and smaller thallus granules.Bacidia absistens(Nyl.) Arnold has an internal apothecium pigmentation similar toB. caesiovirens, but differs in having a smooth thallus, and an abundance of minute crystals in the excipulum.     

ANISOMERIDIUM MUSAESPOROIDES,A NEW FOLIICOLOUS LICHEN FROM TROPICAL AMERICA

A fourth foliicolous species ofAnisomeridiumis described.Anisomeridium musaesporoideshas so far only been found in Guyana and Panama. It is characterized by applanate perithecia with a white marginal zone, large spores with a submedian septum and apical ostiole. A key to all known foliicolousAnisomeridiumspecies is provided.     

PETALIFERA HABEI, A NEW SPECIES FROM JAPAN ADDENDUM

Since Petalifera habei was described in the Proceedings, 34,1, 12–18, April 1960, I have received from Dr. K. Babaa short account of the same species in Publ. Seto. mar. biol.Lab. 7, 3, 337–338. December, 1959, under the title "Thegenus Petalifera and a new species, P. ramosa, from Japan".I was unaware that Dr. Baba intended to describe it. As hispaper antedates mine, his name, Petalifera ramosa, must replaceP. Habei.
