Three new hyphomycetes, Scalecobasidium excentricum, Soloacrospora mic
roverrucosa, and Arachnophora uberisporoides, found on leaf litter in
Cuba, are described and illustrated. The first species is characterize
d by cylindrical to worm-like, 3-5-septate, pale brown, eccentrically
inflated conidia; the second species has fusiform, 0-1-septate, minute
ly verrucose conidia and lacks sterile setae. A. uberisporoides has co
nidia with two dark brown, globose central cells, from which several h
emispherical, 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 Ara
chnophora are keyed out.
