Pseudohalonectria miscanthicola sp. nov. and three interesting fungi from tropics

Pseudohalonectria miscanthicola sp. nov. is reported from senescent culms of Miscanthus floridulus (Gramineae) from Lung Fu Shan, Hong Kong. This fungus differs from other Pseudohalonectria species in having smaller ascospores which are 0-1-septate. It is described, illustrated and compared with other species in the genus. Saccardoella aquatica, first described on submerged wood in Hong Kong and South Africa, is reported here for the first time from dead terrestrial wood at Mount Nicholson, Hong Kong. We also report Massariothea themedae from senescent culms of an unidentified grass from Kudremukh National Park, Karnataka, India. This species is described and illustrated. Important morphological characters of 8 known species of Massariothea are tabulated and a key to all the species is provided. Oxydothis oraniopsis is reported on senescent fronds of Calamus sp. collected from Chorle Ghat, Goa, India. This is the first record of ascomycetous genus Oxydothis from India.
