Dai, Y. C. & Niemelä, T. 2002: Changbai wood-rotting fungi 13. Antrodia sensu lato. — Ann. Bot. Fennici 39: 257–265.
This paper deals with the species of Antrodia (Basidiomycota) in northeastern China. Seventeen species are found in the area, and a key was compiled for the species so far recorded. Statistical variations of spore dimensions are included in the key. A new species, Antrodia leucaena Y.C. Dai & Niemelä, collected on Populus davidiana, is described and illustrated. It is characterized by resupinate to effused-reflexed basidiocarps, and white to cream colour of pore surface, turning brownish when drying. The hyphal structure is dimitic with clamps on generative hyphae, spores are cylindric, and rhomboid or irregular crystal clusters are common in its context and trama. In addition, a non-fertile hymenium has thin-walled hyphidia with apical encrustations. The species seems to be living exclusively on Populus. The closest relatives are A. serialis (Fr.) Donk (having different spores, different set of colours, and growing on conifers), Antrodia macra (Sommerf.) Niemelä (a resupinate species), and A. pulvinascens (Pilát) Niemelä (producing pseudopilei). Five other Antrodia species are briefly discussed.
Dong, W., Dan, Y. & Zhen-yu, L. 2002: Myriophyllum exasperatum (Haloragaceae), a new species from China. — Ann. Bot. Fennici 39: 267–271.
A new species of Myriophyllum from southern China, M. exasperatum D.Wang, D.Yu & Z.Y. Li, is described and illustrated. Features that distinguish the new species are: stems robust, submerged leaves pectinate with 9–13 filiform pinnae; floral bracts mostly spathulate, with 2–4 short teeth on each margin in distal half and obtuse tips; bracteoles simple, broadly lanceolate to ovate, with 4–6 short teeth on each margin and acute tips; flowers uniformly hermaphrodite, sepals orbicular 0.1–0.2 mm long and wide, petals spreading but not recurved-circinate 1.5–1.8 mm long, stamens 8, anthers truncate 1.3–1.4 mm long; and fruits quadrangular, 1.8–1.9 mm long and 1.9–2.0 mm wide, each mericarp laterally flattened with a sharp longitudinally ridge on dorsal surface, finely tuberculate on both ridges and furrows. The new species is most similar to M. tuberculatum from India, Pakistan and Malaysia, to a lesser extent to both M. muricatum from Australia and New Zealand, and M. indicum from Ceylon and south Deccan.
Henssen, A. & Lücking, R. 2002: Morphology, anatomy, and ontogeny in the Asterothyriaceae (Ascomycota: Ostropales), a misunderstood group of lichenized fungi. — Ann. Bot. Fennici 39: 273–299.
Based on morphological, anatomical, and ontogenetical data, the systematics of Asterothyrium, Psorotheciopsis, and Gyalidea (including Solorinella) is revised. The three genera form a natural group for which the name Asterothyriaceae is retained; they share hemiangiocarpous apothecia, true paraphyses, non-amyloid, "annelascaceous" asci, euseptate ascospores, and a chlorococcoid phycobiont. Apothecial ontogeny is characterized by the formation of a covering layer which ruptures during development. Apothecia are sessile (most species of Gyalidea, Psorotheciopsis) or immersed-erumpent with overarching or recurved teeth formed by the covering layer (some species of Gyalidea, Asterothyrium). Flask-shaped, immersed pycnidia (type I) occur in all three genera. Squad-conical pycnidia adnate to the margin of the thallus (type II) were found in Psorotheciopsis and Asterothyrium, while applanate pycnidia immersed in the thallus centre (type III) are restricted to Asterothyrium. All pycnidial types produce conidia of variable size, shape and septation. Several characters shared by Psorotheciopsis and Asterothyrium, i.e. corticate, whitish thalli, pigmented and/or immersed-erumpent apothecia, large and thick-walled ascospores, and frequent formation of pycnidia, are possibly adaptations to their preferred habitat: canopy leaves in the tropical rain forests. The closest relative of the Asterothyriaceae is Gyalideopsis in the Gomphillaceae. It agrees in most aspects with Gyalidea, but differs by its anastomosing paraphysoids and hyphophorous conidiomata. Both families are placed in Ostropales, sharing hemiangiocarpous apothecia, non-amyloid asci, and "annelascaceous" ascus type, with the Stictidaceae, Odontotremataceae, Thelotremataceae, and Graphidaceae.
St. Omer, L. & Barclay, G. 2002: Threatened halophytic communities on sandy coasts of three Caribbean islands. — Ann. Bot. Fennici 39: 301–308.
Three tropical islands — Trinidad, Dominica and St. Lucia — in the British Caribbean were surveyed for location of coastal herbaceous halophytic plant communities native to upper, intertidal sandy beaches. Comparisons of earlier and later drawn topographical maps displayed marked urban expansion indicating the disappearance of native beach vegetation. Hierarchial cluster analysis revealed marked similarities among sites on these islands. Studies of alpha and gamma diversity of the few, viable communities located along back beaches revealed that, like temperate sandy communities, these communities were generally characterized by a small number of perennial halophytic species. At most locations, the community was dominated by only one species — Ipomea pes-caprae — accompanied by a few sub-dominant species. Governments of these islands should consider preserving the few remaining native beach plant communities for future scientific studies.
Potemkin, A. D. 2002: Phylogenetic system and classification of the family Scapaniaceae Mig. emend. Potemkin (Hepaticae). — Ann. Bot. Fennici 39: 309–334.
The phylogenetic system and classification of the family Scapaniaceae Mig. emend. Potemkin as a whole are presented for the first time. The classification of the family is significantly revised. Scapaniaceae is classified with 87 recent and one fossil species in 18 sections and three subgenera of one genus, Scapania (Dumort.) Dumort. emend. Potemkin. Subgenus Scapania has 82 species in 18 sections, subgenus Macrodiplophyllum (H. Buch) Potemkin has three species, and subgenus Macroscapania R.M. Schust. has two species. Earlier distinguished subgenera Plicaticalyx Müll. Frib. and Ascapania Grolle are merged in the sectio Plicaticalyx (Müll. Frib.) Potemkin, comb. & stat. nov., of the subgenus Scapania. The taxonomic composition of many sections is considerably revised, and the species composition of all infrageneric groups is listed in a systematic arrangement. Alteration of the species composition and/or species differentiation (including keys) of the sections Ciliatae Grolle, Gracilidae H. Buch, Nemorosae (Müll. Frib.) H. Buch, Planifoliae (Müll. Frib.) Potemkin, Plicaticalyx, Scapania, and Verrucosae Potemkin of the subgenus Scapania as well as of the subgenera Macrodiplophyllum and Macroscapania are provided. New sections are described for Scapania karl-muelleri Grolle (Grolleoscapania Potemkin, sect. nova) and for S. schljakovii Potemkin and S. himalayica Müll. Frib. (Muelleria Potemkin, sect. nova). A number of new synonyms and index for identification of taxonomic position of mentioned taxa of Scapania are provided.
