Ramophialophora humicola and Fibulochlamys chilensis, two new microfungi from soil.
In a study on soil microfungi from different countries two new hyphomycetes were found. The first one, Ramophialophora humicola, isolated from a soil sample collected in Ronda (Spain), is characterized by producing profusely branched conidiophores ending in sterile, sometimes swollen apices, and subhyaline, dacryoid conidia borne from both integrated and discrete phialides with conspicuous collaretes. ITS sequence data reveal its relationships with members of the Sordariales and its genetic differences with other fungi morphologically close, such as Cladorrhinum spp. The second species, Fibulochlamys chilensis, isolated from a soil sample collected in LaJunta (Chile), is characterized by micronematous, clamped, mostly branched conidiophores producing thallic, one-celled, thick-walled conidia that exhibit strongly wrinkled surfaces in age. The analysis of partial sequences of the ITS region and 28S rRNA gene reveal that this fungus is close to members of the gilled Agaricales.
