Aliquandostipitaceae, a new family for two new tropical ascomycetes with unusually wide hyphae and dimorphic ascomata

In two short surveys of lignicolous, fruitbody-forming ascomycetes in Thail and and southern China, six species were found, of which five were new to s cience. Two fungi with affinity to the Dothideomycetes, one from Thailand a nd one from China, are described here in the new genus Aliquandostipite and included in the new family Aliquandostipitoceae. Aliquandostipite khaoyaie nsis 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 base d on morphological and molecular characteristics and with uncertain affinit y to other taxa of the Euascomycetes based on phylogenetic analyses of SSU rDNA sequences. The distinguishing features of the new species are the pres ence of both sessile and stalked ascomata side by side on the substratum an d the widest hyphae known from ascomycetes.
