Clathrosporium Nawawi & Kuthubutheen is found to be synonymous with Strumella Sacc. (lectotypified by Strumella olivatra (Sacc.) Sacc.), a later illegitimate homonym of Strumella Fr. Consequently, Strumella olivatra is redisposed in Clathrosporium, alongside the type species Clathrosporium intricatum Nawawi & Kuthubutheen. Two new species, Clathrosporium delicatum Hennebert sp.nov. and Clathrosporium compactum Hennebert n.sp., are described and illustrated. These hyphomycetes are aeroaquatic, growing on periodically submerged plant material, leaves, and rotten wood. They produce pigmented, multicellular propagules comprising coiled, branching hyphae that disarticulate into arthroconidia when mature.Key words: aeroaquatic, hyphomycete, Clathrosporium olivatra, Clathrosporium vinosa, Clathrosporium delicatula, Clathrosporium compacta, Strumella, Spirosphaera, taxonomy.
