A new species, Exserticlava aquatica, collected on submerged decaying twigs in Pará State in the Brazilian Amazon, is described and illustrated. The microfungus is characterized by monoblastic ...conidiogenesis with repeated percurrent conidiophore extensions and conidiogenous
cells with a slightly swollen apex that does not protrude beyond the ruptured outer wall.
Distophragmia gen. nov. is established to accommodate Endophragmiella rigidiuscula based on the type of conidial septa. Descriptions and illustrations are provided.
A new genus and species Anisogenispora insignissima is described and illustrated. The fungus, found on decaying fruit of an unidentified dicotyledonous plant, is distinguished by blastic production ...of globose to broadly pyriform, 1-2-septate, bicolored conidia and a
Thielaviopsis-like synanamorph with lenticular, doliiform, cylindrical, or vermiform, unicellular or multiseptate, black conidia produced by thallic-arthric disarticulation. All conidiogenous events originate on the same conidiophores.
Alcornia is proposed as a new monotypic genus differentiated from Parapericonia by its tretic conidiogenous cells and rhexolytic conidial secession; a new combination Alcornia sessilispora is also ...proposed, based on P. sessilispora. Distoceratosporella
digitiformis is proposed as a new genus and species distinguished from Ceratosporella by its distoseptate conidia. These taxa are described and illustrated. Additionally, the new combinations Distoceratosporella amazonica, D. hernandezii, and D. longiramosa
are proposed, all with Ceratosporella basionyms.
Digicatenosporium polyramosum gen. & sp. nov., collected on the decaying bark of an unidentified dicotyledonous plant in Bahia, Brazil, is described and illustrated. This species is unique in its ...distinct unbranched conidiophores, monoblastic integrated determinate conidiogenous
cells, and highly digitate branched blastocatenate reddish to yellowish brown or brown conidia.
In the course of studies about conidial fungi that grow on plant debris in the semi-arid region of Brazil, four species of Paliphora were found on unidentified dicotyledonous plants. Paliphora ...intermedia and P. porosa are recorded for the first time for South America and the neotropics respectively. Paliphora inflata and P. multiseptata are proposed as new species. A key and synoptic table of characters of the five known species of Paliphora are provided.

A new helicosporous fungus, Helicosporium vesiculiferum, is described based on morphological characters. It was found on a decaying twig of an unidentified dicotyledonous plant from the semi-arid ...region, Northeast of Brazil. The new species is illustrated with light micrographs
and scanning electron microscopy. Helicosporium vesiculiferum is characterized by the presence of vesicles on apex of the conidiophores. Seven helicosporous species are briefly described, of which H. virescens and H. aureum are new records from Brazil, H. panacheum
and H. gracile are reported for the first time in South America, and H. nizamabadense is new for the American continent. A key to all Helicosporium species is included.
Two new species found on dead bark and fruit in Brazilian semi-arid region are described and illustrated. Endophragmiella tuberculata sp. nov. is characterized by obovoid, 1-septate, verrucose ...conidia, and can be distinguished from similar Endophragmiella species by the
distal cells of its conidia with conspicuous tubercules. Spegazzinia flabellata sp. nov. has two types of conidia: a-globose to subglobose, simple, strong spinulose and b-co-planate, with four quadrangular cells, finely spinulose; it can be separated from earlier
described Spegazzinia species by a-type conidia with conspicuous spines. Dictyoarthrinium sacchari is reported for the first time from Brazil. Furthermore, E. collapsa and E. dimorphospora are new records for Neotropica and South America respectively.
