In two short surveys of lignicolous, fruitbody‐forming ascomycetes in Thailand and southern China, six species were found, of which five were new to science. Two fungi with affinity to the Dothideomycetes, one from Thailand and one from China, are described here in the new genus Aliquandostipite and included in the new family Aliquandostipitaceae. Aliquandostipite khaoyaiensis was found in a tropical rain forest in Thailand and A. sunyatsenii in a small stream in southern China. Both new species are closely related based on morphological and molecular characteristics and with uncertain affinity to other taxa of the Euascomycetes based on phylogenetic analyses of SSU rDNA sequences. The distinguishing features of the new species are the presence of both sessile and stalked ascomata side by side on the substratum and the widest hyphae known from ascomycetes.
