Abstract
Cochlonema calosperma is descr. from agar plate cultures that were planted with decaying detritus of Spartina sp. originating from Maryland. It habitually parasitizes an Amoeba, perhaps A. terricola, APLECTOSOMA microsporum, obtained from decaying Salix leaves collected in Md., is dis-tinguished by a quadrilobate or quinquelobate pillowy thallus that develops endoparasitically in a rather small Amoeba sp.; from each lobe it gives rise to an aerial chain of small conidia. Acaulopage lophospora, obtained from detritus of Lonicera leaves originating in n.-e. Md., produced warty zygospores. In cultures planted with grass and with sedge detritus from Md. the testaceous rhizopods Arcella dlscordes and Difflugia constricta were often found occupied by a coarse branching zoopagaceous mycelium unaccompanied by any sexual or asexual reproductive stage. A small Amoeba of the limax type that developed in agar plate cultures planted with straw of Hordeum vulgare from Colorado was frequently parasitized by a rather minute form distinguished by a U-shaped thallus often narrowly connected with a single external conidium. A sp. of Euryancale considerably more robust than E. sacciospora was found developing from a dead nematode in a culture that had been planted with deciduous leaf mold from Wisconsin.This publication has 0 references indexed in Scilit:
