Strigula porinoides Canals, Boqueras &
G6mez-Bolea (in press)
According to C. Roux (in lin.) , our s pecimens
correspond to a new species which is goiog to be
described from Catalonia by CANALs & al. (in press).
The new species is characterized by the following
combìnation of characters : protrudiog perithecia
with a dimidiate involucrellum ; hyaline excipulum;
fusiform, halonate, submuriform or weakly muriform
spores with 7-10 (12) transversal and 1-4 longitudi-
nal septa, measuring 24-34 x 6-8 (9) J.1ffi; macro-
pycnidia with dark brown apical part ; macroconidia
with (5) 7 transversal and, rarely, l or 2 loogitudinal
septa, measuring 19-26 (35)x 4.5-6.5 (8.5)pm.
Strlgula endolithea Bricaud & Roux ad int. (Roux
& BRICAUD, 1991), resembles S. p orinoides in the
macroconidia with (5) 7 transversal septa, but
clearly differs in the following characters (Roux, in
litt.) : macroconidia muc b narrower [(3.5-4-4 5
(5) pm), without longitudinal septa ; macropyc nidia
almost entirely hyaline ; perithecia unknown.
On shaded surfaces of calcareous rocks at 400m
(TSB). New to ltaly.
