ABSTRACT
Four new lignicolous species of the family Hysteriaceae (Gloniella gracilis, Graphyllium panduratum, Hysterium asymmetricum and Hysterographium pulchrum) are described from Costa Rica based in their macroscopic and microscopic characters.

Two new ascomycetes, Boerlagiomyces costaricensis (Pleosporales) and Scopinella musciformis (Sordariales sensu lato), from litter samples collected in rainforests of Costa Rica, are described and illustrated. Boerlagiomyces costaricensis has globose, ostiolate ascomata covered by numerous setae-like hairs; cylindrical, fissitunicate asci without apical structures; and large, fusiform, muriform, hyaline to pale brown ascospores. Scopinella musciformis is characterized by ostiolate ascomata with a few compact clusters of hypha-like hairs distributed on the peridial surface and a long neck; ovate to ellipsoidal unitunicate asci; and small quadrangular ascospores with diagonal germ slits.

Bone marrow cultures in semi-solid medium provide an estimate of progenitors in granulopoiesis and also in erythropoiesis. They are available data in leukemias and in bone marrow grafts. The cytogenetic studies of the abnormal clones show numeric and structural-abnormalities depending from the different types of leukemias and from the course of the disease.

The more frequent practise of X-ray examination shows that symphalangism may be involved by other synostosis. Maroteaux described in 1972 "multiplex synostosis disease". Seven personal cases (all female) in two families are described with particular problem of deafness and vertebral fusion. Dominant autosomic inheritance.
