Laboulbeniales (Ascomycetes) from Latvia ANDRÉ DE KESEL and INGUNA KRASTINA DE KESEL National Botanic Garden of Belgium, Domein van Bouchout B 1860 Meise, adk@br.fgov.be D e K e s e l A., K r a s t i n a D e K e s e l I.: Laboulbeniales (Ascomycetes) from Latvia. Acta Mycol. 41 (1): 55 64, 2006. This contribution presents new and historical data on the Laboulbeniales of Latvian Coleoptera. An annotated checklist of 26 taxa is given, 13 are new for Latvia. Only six taxa (accepted names) from Briedis’ historical list were found again and six more need to be confirmed as Briedis’ material was lost. A neotype is indicated here for the extremely rare Laboulbenia elaphricola Siemaszko et Siemaszko. Its morphology is discussed and compared with Laboulbenia elaphri Spegazzini and Laboulbenia vulgaris Peyr. Key words: Laboulbeniales, Latvia, Coleoptera, Laboulbenia elaphricola INTRODUCTION Laboulbeniales (Ascomycetes) are strictly parasitic on Arthropoda, mainly in- sects. Although widespread, information concerning their distribution in Europe is unequal and, as yet, a reflection of the distribution of laboulbeniologists in Europe (We i r , R o s s i 1995). The most exhaustive studies were carried out in Spain and Poland, followed by France, Finland, Britain, Italy, Belgium, Germany and Hungary. From other European countries, including the Baltic countries, only very few and iso- lated reports or collections are available. Records from Estonia and Lithuania have been published in S i e m a s z k o and S i e m a s z k o (1928, 1932), H u l d é n (1985) and M a r k o v s k a j a (2000) respectively. In Latvia 16 species of Laboulbeniales have been recorded in the literature (B r i e d i s 1932; H u l d é n 1985). All species were found on ground beetles (Coleoptera, Carabidae) and all, but one Misgomyces, belong to Laboulbenia. A thorough study of Briedis’ material and notes was not pos- sible as it could not be located; we consider it lost. This paper reports on newly collected material and literature records of Laboulbeniales found on Latvian Coleoptera (Carabidae and Staphylinidae). ACTA MYCOLOGICA Vol. 41 (1): 55-64 2006 Dedicated to Professor Alina Skirgiełło on the occasion of her ninety fifth birthday 56 A. De Kesel and I. Krastina De Kesel MATERIALS AND METHODS Carabidae and Staphylinidae (Coleoptera) were captured by hand or by means of pitfall traps. Sampling sites are situated in Latvia and mainly include river associ- ated forests, riverine marshes and banks along the river Gauja and Abuls (Valmiera raijons). Samples were also taken in the plant debris zones along the shorelines of the Baltic Sea, near Jurmala (Majori) and Pabazi (Balta Kapa). Hosts were killed and stored in 70 or 90% denaturated ethanol. Screening hosts for infections and pre- paring of thalli was done using a stereomicroscope at high magnification (25-50x). The thalli were mounted and stained in permanent slides using a medium based on Arabic gum with cotton blue and a trace of glycerine (D e K e s e l 1998). Field data (locality, GPS-coordinates, date and habitat), host data (taxon, gender and infec- tion site) and parasite data (taxon, number of specimens and development) were recorded. Slide(s) from the Laboulbeniales and the corresponding hosts were given the same number (i.e. DKK-number); all material and notes are deposited at BR (Herbarium National Botanic Garden of Belgium). When specific identity of a host was doubtful only the generic name of the host was used, followed by sp. The generic taxonomy of Staphylinidae follows L o h s e (1964) and L o h s e et al. (1974), for Cara- bidae L i n d r o t h (1974) or F r e u d e (1976). Nomenclature and identification of all Laboulbeniales found in Latvia is largely based on ‘The Laboulbeniales of Poland’ by T. M a j e w s k i (1994). We consider it a key reference work for the study of the Laboulbeniales from the Baltics. To avoid redundancy we refrained from giving exhaustive species descriptions and comments, unless complementary to the information given in M a j e w s k i (l.c.) or elsewhere. RESULTS Annotated and preliminary checklist of the Laboulbeniales from Latvia In the following checklist we placed species in bold when they correspond with verified records, i.e. species found by us in 2004-2005 and with reference material in Herbarium BR.

Laboulbenia elaphricola Siemaszko et Siemaszko * • On Elaphrus riparius (L.) (Coleoptera, Carabidae). DKK38(a,b): Valmiera, Gauja, tributary Misa, 04.06.2005, N57°31.08’ – E025°26.52’, under litter, along rivulet bank in forested zone; DKK61, DKK62, DKK66: ibidem s.l., 03.06.2005, N57°32”0.5” – E025°26’49.2”, along rivulet banks; DKK42: Brenguli, river Abuls, 31.05.2005, N57°32’56.2” – E025°32’24.3”, along rivulet bank in forested area. Thalli are found all over the hosts’ integuments, but most thalli occur on the elytra and the pronotum. Laboulbenia elaphricola was described by S i e m a s z k o and S i e m a s z k o in 1928 (Pol. Pismo Entomol. 6, pg. 200, T.VII, Fig. 2). It was found in Eastern Poland, Pu- lawy, on Elaphrus riparius L. The original description is very short and the drawing of the type represents a damaged and incomplete outer appendage. The type material was unfortunately lost during WWII (M a j e w s k i 1994). Since its description only B à n h e g y i (1950) reported L. elaphricola, but stated later that his material belongs to L. elaphri (B à n h e g y i 1964). L. elaphricola seems to be a very rare species, be- cause very intensive screening of suitable habitats in Eastern Poland, Bialowieza (M a j e w s k i 2003) did not supply new material. Today it is a species with an uncer- tain status. In the absence of information on its full morphology and eventual posi- Laboulbeniales (Ascomycetes) from Latvia 59 tion related variations, B à n h e g y i (1964) and M a j e w s k i (1994) suggested that it could just be a growth form of the more common Laboulbenia elaphri Spegazzini. The numerous specimens we could collect on Elaphrus riparius from Latvia cor- respond with L. elaphricola. Our material confirms that this species is not a growth form of L. elaphri as its typical short and stout thalli occur invariably on different parts of the hosts’ integument. L. elaphricola is indeed a small and dark species and no forms, even closely resembling L. elaphri, were seen on the studied hosts. We consider S i e m a s z k o and S i e m a s z k o ’ s L. elaphricola a good species. It is very distinct from L. elaphri and actually close to L. vulgaris, as already stated by S i e - m a s z k o and S i e m a s z k o (1928). The following diagnosis and figure 1 should help to separate it from L. vulgaris. - All thalli of L. elaphricola are small and stout, invariably of their origin on the host. They are never longer than 220μm (foot-ostiolum). - Already in an early stage of development L. elaphricola shows a deep pigmenta- tion of the receptaculum. Except for the poorly and uniformly pigmented cell I, cell II and septum I-II, all adult specimens have a deeply pigmented to blackish thallus. In L. vulgaris the septum I-II is often darker, a feature that lacks in L. elaphricola. - The perithecium is more free in L. elaphricola than in L. vulgaris, i.e. the inser- tion cell and cell V always being slightly below the middle of the perithecium in L. elaphricola. - Cell II of L. elaphricola almost immediately widens upwards, forming a strik- ingly long septum with cell VI and a short septum with cell III. Cell VI is much broader than high. In most cases the septum II-VI is at least twice the length of septum II-III. - The upper receptacle, i.e. the complex of cells III, IV and V, is delimited or demarcated from the rest of the thallus by a very deeply pigmented line, even in very young thalli. This darkened line starts at the anterior side of the insertion cell (close to the perithecium). It continues downwards along the adaxial septa of cell V, cell IV and cell III, makes a curves along the basal septum of the latter, to finally end at the posterior (dorsal) side of the receptacle. - The outer appendage is not branched and relatively long. In many cases, but not always, the three basal cells of the outer appendage tend to be slightly inflated. Specimens with a branched outer appendage occur very rarely and only as a re- sult of damage and subsequent atypical regeneration of the appendage. The inner appendage is branched once or twice and never exceeding the ostiolum. - The insertion cell is constricted, sometimes strongly. The name bearing type material of L. elaphricola is lost and since its description L. elaphricola was not found again in Poland or elsewhere (Majewski pers. comm.). In this context we indicate our collection DKK62 (kept at BR) from Latvia as neo- type for Laboulbenia elaphricola Siemaszko et Siemaszko. This material was obtained from the elytra of Elaphrus riparius L., caught on 03.VI.2005 along the forested banks of a tributary of the river Gauja in Valmiera (Latvia, N57°31.08’ – E025°26.52’).

Laboulbenia polyphaga Thaxt., i.e. var. calathicola probably to be considered a record of L. calathi CONCLUSIONS - Twenty six species are reported for Latvia, 13 are new for the studied territory. - Six species reported by B r i e d i s (1932) were confirmed. - The presence of six more species, reported by B r i e d i s (1932) and H u l d é n (1985), needs to be confirmed with new material as Briedis’ original material from Latvia is untraceable. - Laboulbenia elaphricola Siemaszko et Siemaszko is reported for Latvia. This taxon is extremely rare and not reported, with certainty, since its discovery. It has an uncertain status because of a very short original diagnosis. The name bearing type was unfortunately lost and L. elaphricola is currently considered a growth form of L. elaphri. The Latvian material, however, provides enough evidence that L. elaphricola is a good species. 64 A. De Kesel and I. Krastina De Kesel REFERENCES B á n h e g y i J. 1950.

Gatunki Laboulbeniales (Ascomycetes) z terenu Łotwy S t r e s z c z e n i e W artykule przedstawiono zarówno nowe jak i historyczne dane o gatunkach Laboulbe niales występujących na łotewskich Coleoptera, przede wszystkim na Carabidae i Staphyli nidae. Odnotowano 26 gatunków, z których 13 jest nowych dla Łotwy. Pierwsza lista gatun ków Laboulbeniales z Łotwy została opublikowana w roku 1932 przez Briedisa w Acta Horti Botanici Universitatis Latviensis. Kolekcja Briedisa najprawdopodobniej zaginęła. Sześć po twierdzonych taksonów z listy Briedisa zostało na nowo odnalezionych, a dalsze sześć należy odszukać. Krytyczna lista 26 gatunków zawiera również uwagi taksonomiczne dotyczące m. in. Laboulbenia elaphricola Siemaszko et Siemaszko. 2014-01-01T11:43:29+0100 Polish Botanical Society
