Notes<br />
Morphology<br />
Chaetomastia was introduced by Saccardo (1883) asa<br />
subgenus of Melanomma, and five species were included,<br />
i.e. M. canescens Speg., M. cucurbitarioides Speg.,<br />
M. hirtulum (P. Karst.) Sacc., M. hispidulum Sacc. and<br />
M. pilosellum P. Karst. Berlese (1890) promoteditto<br />
genus rank. Subsequently, Chaetomastia hirtula (P.<br />
Karst.) Berl. was selected as the lectotype species of<br />
the genus (Clements and Shear 1931). Chaetomastia has<br />
been regarded as having unitunicate asci (Eriksson and<br />
Hawksworth 1986, 1998; Eriksson 1999). However its<br />
bitunicate status was confirmed by Holm (1957). Holm<br />
(1957) treated C. hirtula as Melanomma hirtulum (P.
