NEW SPECIES AND NEW RECORDS OF GENUS BOLETELLUS FROM CHINA

The diagnosis of the genus Boletellus has been modified by some myco-taxonomists since it was established by Murrill in 1909. Singer has included the species with ornamented spores (ridged, reticulate or punctate fromabove) as well as some with smooth spores. At present, we agree with A. H. Smith's definition of this genus. Eight species are reported in this paper. Their spores are ornamented with longitudinal ridges or striates. Two species are new to science (Boletellus fanjingensis Wen, Bo-letellus fujianensis Wen), and two species as new records to China (Boletellus ba-diovinosus Horak, Boletellus obscurecoccineus (Hohn.) Singer. Boletellus fanjingensis Wen is similar to B. chrysenteroides (Snell) Snell in many respects, but its flesh and tubes are turning blue when bruised, then rufescent. The pileus, basidia and cystidia also differ from those of B. chrysenteroides (Snell) Snell in size and color. Boletellus fujianensis Wen is close to B. emodensis (Berk.) Sing., but is distinguished by its flesh color of the pileus remaining unchanged when bruised and the tubes being adnate. The characteristic of unchanging color is similar to Boletellus obscurecoccineus (Hohn.) Sing., but the size of their spores is quite different. Specimens are deposited in the Mycological Herbarium of Institute of Microbiology, Academia Sinica, Beijing.
