<Emphasis Type="Italic">Fusarium matuoi</Emphasis> sp. nov. and its teleomorph <Emphasis Type="Italic">Cosmospora matuoi</Emphasis> sp. nov.

A group of Fusarium isolates from slime flux similar to F. aquaeductuum produced unique, strongly curved, aseptate, C-shaped conidia. They were found to be identical to F. splendens nom. nud. Dried specimens from which F. splendens was originally isolated were reexamined and characterized as a new species of Cosmospora. Cosmospora matuoi sp. nov. is proposed for the teleomorph, and Fusarium matuoi sp. nov. is proposed for its anamorph.     

A new hyphomycete genus and species with pectinate conidia from a rainforest in Panama—a living fungal fossil?

A species of hyphomycetes, characterized by hyaline cells and asymmetric, pectinate (comblike) conidia, was collected on a dead fern rachis and on old conidiophores of the dematiaceous hyphomycete Dischloridium sp. in a rainforest in Western Panama. The structure of the conidia of the new species was previously known only for species of the fossil genus Ctenosporites. A new genus and species are proposed for the fungus from Panama.

CODONMYCES AND LICHENOSTELLA,TWO NEW GENERA OF LICHENICOLOUS CONIDIAL FUNGI

The new generic names Codonmyces and Lichenostella are introduced for two new species of conidial fungi. Lichenostella hypotrachynae gen. et sp. nov. is a commensal of Hypotrachyna species, and is mainly characterized by forming black sporodochia with setae and, particularly, by its star-like conidia. Codonmyces lecanorae gen. et. sp. nov. occurs on Lecanora valesiaca and differs from the genus Xanthoriicola by its 1-septate conidia and campanulate conidiogenous cells with several conspicuous, flared annellations. Comments on the ecology ofL. valesiaca , and its associated lichens and lichenicolous fungi are also given.     

Minteriella cenotigena anam. gen. & sp. nov. from submerged plant material in Mexico

Minteriella cenotigena gen. & sp. nov., found on decaying bark submerged in a sinkhole from the southern of Mexico, is described and illustrated. The new taxa is distinguished by synnematous conidiomata, with polyblastic, discrete, indeterminate, sympodially proliferating conidiogenous cells, with flat conidiogenous loci and cylindrical, 3- to 4- (to 5) euseptate, hyaline conidia.     

Five additional genera of conidial lichen-forming fungi from Europe

Three remarkable new genera of conidial lichen-forming fungi, with pycnidial or acervular conidiomata are described and illustrated.Hastifera tenuispora gen. et spec. nov. from the South-Tyrol, Italy, is characterized by very long and narrow hyaline conidia produced in pycnidial conidiomata immersed in thalline warts.Lichingoldia gyalectiformis gen. et spec. nov. from rocks subject to inundation by freshwater in Norway has long sigmoidly curved conidia which appear to be adapted to dispersal in water.Woessia fusarioides gen. et spec. nov. from aQuercus stump in the Burgenland, Austria, has a finely granular thallus and disc-like conidiomata producing falcate conidia; this species is also of interest in that it hasChlorella as the photobiont. The recently described hyphomyceteCheiromycina flabelliformis B. Sutton is reported from Austria for the first time, and is also lichenized. Recent collections ofNigropuncta rugulosa D. Hawksw. from Austria and Italy also show that this species is lichenized rather than parasymbiotic. In all five cases the fungal hyphae of the conidiogenous structures are continuous with those in intimate contact with cells of the algal partners and the biological relationship appears to be mutualistic giving rise to stable crustose lichen thalli.     

New species of Dictyochaetopsis and Paraceratocladium from Brazil

Two new conidial fungi, Dictyochaetopsis brasiliensis and Paraceratocladium bacilliformis, both isolated from plant debris collected in Brazil, are described and illustrated. Dictyochaetopsis brasiliensis differs from the previously described species of the genus mainly by small, fusiform conidia with a very thin apical setula, absence of setae, and lateral, discrete conidiogenous cells with usually numerous sympodial proliferations. Paraceratocladium bacilliformis is characterized by small, bacilliform and aseptate conidia.

Spirobolbolaimus bathyalis,gen. nov., sp. nov. (Nematoda,Microlaimidae) from the Mediterranean (Calvi)

Spirobolbolaimus bathyalis gen. nov., sp. nov. is described from the continental slope off Calvi (Mediterranean). The new genus Spirobolbolaimus belongs to the Microlaimidae Micoletzky, 1922 and is closely related to the genus Bolbolaimus Cobb, 1920. It can be differentiated from Bolbolaimus by its multispiral amphideal fovea and by its six rows of postamphideal setae.     

Taxonomy of an anamorphic xylariaceous fungus from a termite nest found together with <Emphasis Type="Italic">Xylaria angulosa</Emphasis>

Two xylariaceous fungi were isolated from a nest of a termite, Odontotermes formosanus, that was incubated in a laboratory after collecting from Iriomote Is., Okinawa Pref., in Japan. One of the two fungi was identified as Xylaria angulosa on the basis of the morphology of branched stroma produced on medium, tiny asci, and ascospores having a germ slit. Another fungus is an anamorphic fungus that produces synnemata up to 50 mm long from which dendritic conidiophores branch out. Unicellular conidia are holoblastically produced on a sympodially proliferating conidiogenous cell. Such morphological characters resemble those of the genus Geniculosporium. However, its distinctive synnema formation and dendritic conidiophores do not assign the fungus to Geniculosporium or other known genera and warrant establishment of a new genus. The phylogenetic tree based on the ITS regions of rDNA shows that the fungus is nested in the cluster of the genus Nemania (Xylariaceae), whose species have mainly Geniculosporium-like anamorphs. We describe here the present anamorphic fungus as Geniculisynnema termiticola gen. et sp. nov., and discuss its phylogenetic and ecological relationships to xylariaceous fungi, especially termiticolous species.     

Taxonomy and Phylogeny of Synchaetomella Lunatospora, a New Genus and Species of Synnematous Fungi from Southeast Asia

The anamorphic fungus Synchaetomella lunatospora gen. et sp. nov. is described from a culture isolated from leaf litter in Singapore. The genus is characterized by the production of synnematous conidiomata with brown stipes, phialidic conidiogenesis with terminal and acropleurogenous conidiogenous cells, and falcate, 1-septate conidia, aggregating in white, mucilaginous heads. Its phylogenetic relationships, inferred from the partial nuclear small ribosomal subunit (18S) sequence, are with the coelomycetous genera Sphaerographium, Chaetomella, and Hainesia. However, the order and family affinities of this group are unclear.     

Myxotrichum albicans,a new slowly-growing species isolated from forest litters in China

Myxotrichum albicans sp. nov. is a slowly-growing fungal species that was isolated from forest litters in northeast of China. The new species is morphologically characterized by its white colonies on CMA, PCA, PDA, and YMA, thallic conidiogenous cells, simple, catenate and hyaline conidia. Phylogenetic analysis based on internal transcribed spacer (ITS) and large subunit (LSU) rDNA sequences also supported the placement of M. albicans as a new species in the genus Myxotrichum. To compare with related species, the optimal pH and temperature for growth were investigated. The differences among Myxotrichum (Oidiodendron) species producing hyaline conidia were discussed.     

Tremella occultifuroidea sp. nov., a new mycoparasite ofDacrymyces

Tremella occultifuroidea, a new parasite of dacrymycetaceous fungi is described. It differs from knownTremella parasites in dacrymycetaceous hosts by thick-walled dikaryotic conidia, terminally and repeatedly originating from conidiogenous cells, thus resembling those ofT. polyporina by Koske,T. obscura by Christiansen andOccultifur internus.

Three new hyphomycetes onPandanus leaves from mauritius

Three new hyphomycetes colonizing dead leaves ofPandanus spp. in Mauritius are described, illustrated, and compared with related species. They areFuscophialis suttonii sp. nov.,Paraceratocladium triseptatum sp. nov., andSporidesmium paradecorosum sp. nov.     

Janetia obovata and Stachybotryna excentrica, two new hyphomycetes from submerged plant material in Spain

Janetia obovata and Stachybotryna excentrica, two new hyphomycetes from submerged litter collected in different Mediterranean localities in Spain, are described and illustrated. Janetia obovata possesses denticulate and dark pigmented conidiogenous cells characteristic of the genus, but is mainly distinctive in producing obovoid and unevenly pigmented conidia. Stachybotryna excentrica is hyaline and produces setae as do all members of the genus, but is distinctive by its small conidia that are cylindrical or ellipsoidal in front view and slightly allantoid in side view with a protuberant eccentric scar, and its long subcylindrical setae. A key to Stachybotryna species is provided.
