Abstract: The 9th fascicle (30 numbers) of the exsiccata 'Lichenicolous Biota' is published. The issue contains ma- terial of 20 non-lichenized fungal taxa (14 teleomorphs of ascomycetes, 4 anamorphic states of ascomycetes, 2 an- amorphic states of basidiomycetes) and 9 lichenized as- comycetes, including paratype material of Dimelaena li- chenicola K.Knudsen et al. (no 223), Miriquidica invadens Hafellner et al. (no 226, 227), and Stigmidium xantho- parmeliarum Hafellner (no 210). Furthermore, collections of the type species of the following genera are distributed: Illosporiopsis (I. christiansenii), Illosporium (I. carneum), Marchandiomyces (M. corallinus), Marchandiobasidium (M. aurantiacum, sub Erythricium aurantiacum), Micro- calicium (M. disseminatum), Nigropuncta (N. rugulosa), Paralecanographa (P. grumulosa), Phaeopyxis (P. punc- tum), Placocarpus (P. schaereri), Rhagadostoma (R. li- chenicola), and Stigmidium (S. schaereri). *Institut für Pflanzenwissenschaften, NAWI Graz, Karl-Franzens-Universität, Holteigasse 6, 8010 Graz, AUSTRIA e-mail: [email protected] Introduction The exsiccata 'Lichenicolous Biota' is continued with fascicle 9, containing 30 numbers. The exsiccata covers all lichenicolous biota, i.e., it is open not only to non- lichenized and lichenized fungi, but also to myxomycetes, bacteria, and even animals, whenever they cause a characteristic symptom on their host (e.g. discoloration or galls). -

ADVAITA, CALEB A. MORSE1,2 AND DOUGLAS LADD3 ABSTRACT. – A total of 154 lichens, four lichenicolous fungi, and one allied fungus were collected by the authors from 2004 to 2015 from Pipestone National Monument (PNM), in Pipestone County, on the Prairie Coteau of southwestern Minnesota. Twelve additional species collected by previous researchers, but not found by the authors, bring the total number of taxa known for PNM to 171. This represents a substantial increase over previous reports for PNM, likely due to increased intensity of field work, and also to the marked expansion of corticolous and anthropogenic substrates since the site was first surveyed in 1899. Reexamination of 116 vouchers deposited in MIN and the PNM herbarium led to the exclusion of 48 species previously reported from the site. Crustose lichens are the most common growth form, comprising 65% of the lichen diversity. Sioux Quartzite provided substrate for 43% of the lichen taxa collected. Saxicolous lichen communities were characterized by sampling four transects on cliff faces and low outcrops. An annotated checklist of the lichens of the site is provided, as well as a list of excluded taxa. We report 24 species (including 22 lichens and two lichenicolous fungi) new for Minnesota: Acarospora boulderensis, A. contigua, A. erythrophora, A. strigata, Agonimia opuntiella, Arthonia clemens, A. muscigena, Aspicilia americana, Bacidina delicata, Buellia tyrolensis, Caloplaca flavocitrina, C. lobulata, C. -

Abstract: A set of morphoanatomical characters and the amy- loid reaction of the ascomatal centrum indicates that Microthelia umbilicariae Linds. belongs to Endococcus (Verrucariales). En- dococcus freyi Hafellner, detected on Umbilicaria cylindrica (type locality in Austria), is described as new to science. The new combinations Endococcus umbilicariae (Linds.)

Over the time, 277 species and infraspecific taxa have been assigned to Microthelia, now a rejected generic name against the conserved genus Anisomeridium (Müll.Arg.) M.Choisy. In the second half of the 19th century also several lichenicolous fungi have either been described in Microthelia, namely by the British mycologist William Lauder Lindsay (1829–1880), or have been transferred to Microthelia by combination. -

Endocarpon thalli are squamulose to subfruticose, whereas Willeya and Staurothele include only crustose species. Endocarpon pulvinatum, an arctic-alpine species newly reported for Iceland, is one of the few Endocarpon with a subfruticose thallus formed by long and narrow erected squamules. Molecular phylogenetic analyses of four loci (ITS, nrLSU, mtSSU, and mcm7) newly obtained from E. pulvinatum specimens from Iceland, Finland and North America does not confirm its current classification within the mostly squamulose genus Endocar- pon, but instead supports its placement within the crustose genus Staurothele. The new combination Staurothele pulvinata is therefore proposed here. It includes also E. tortuosum, which was confirmed as a synonym of E. -
New Species and New Records of American Lichenicolous Fungi
DHerzogiaIEDERICH 16: New(2003): species 41–90 and new records of American lichenicolous fungi 41 New species and new records of American lichenicolous fungi Paul DIEDERICH Abstract: DIEDERICH, P. 2003. New species and new records of American lichenicolous fungi. – Herzogia 16: 41–90. A total of 153 species of lichenicolous fungi are reported from America. Five species are described as new: Abrothallus pezizicola (on Cladonia peziziformis, USA), Lichenodiplis dendrographae (on Dendrographa, USA), Muellerella lecanactidis (on Lecanactis, USA), Stigmidium pseudopeltideae (on Peltigera, Europe and USA) and Tremella lethariae (on Letharia vulpina, Canada and USA). Six new combinations are proposed: Carbonea aggregantula (= Lecidea aggregantula), Lichenodiplis fallaciosa (= Laeviomyces fallaciosus), L. lecanoricola (= Laeviomyces lecanoricola), L. opegraphae (= Laeviomyces opegraphae), L. pertusariicola (= Spilomium pertusariicola, Laeviomyces pertusariicola) and Phacopsis fusca (= Phacopsis oxyspora var. fusca). The genus Laeviomyces is considered to be a synonym of Lichenodiplis, and a key to all known species of Lichenodiplis and Minutoexcipula is given. The genus Xenonectriella is regarded as monotypic, and all species except the type are provisionally kept in Pronectria. A study of the apothecial pigments does not support the distinction of Nesolechia and Phacopsis. The following 29 species are new for America: Abrothallus suecicus, Arthonia farinacea, Arthophacopsis parmeliarum, Carbonea supersparsa, Coniambigua phaeographidis, Diplolaeviopsis -
