Three new conidial fungi (hyphomycetes) from Cuba

Three new hyphomycetes, Scalecobasidium excentricum, Soloacrospora microverrucosa, and Arachnophora uberisporoides, found on leaf litter in Cuba, are described and illustrated. The first species is characterized by cylindrical to worm-like, 3-5-septate, pale brown, eccentrically inflated conidia; the second species has fusiform, 0-1-septate, minutely verrucose conidia and lacks sterile setae. A. uberisporoides has conidia with two dark brown, globose central cells, from which several hemispherical, obtuse, subhyaline, unbranched, one-celled arms arise. A new combination, Arachnophora polyradiata, is proposed for Cacahualia polyradiata Mercado & Castaneda and the six species recognized in Arachnophora are keyed out.
