Caudatispora biapiculata, a new species based on Puerto Rico material, is d
escribed and illustrated and compared with the only other species in the ge
nus, C. palmicola. Caudatispora is characterized within the Lasiosphaeriace
ae by superficial clusters of reddish brown ascomata and hyaline, ellipsoid
ascospores with apiculate ends. C. biapiculata differs from the other spec
ies in ascospores with wall extensions at the apical and basal ends and in
their eventual pale brown coloration and presence of a single septum.
