at each end, dark brown when mature, 17-21 X3.5 mu, typically 
3-septate with the two terminal cells much smaller than the other 
cells. 
On Meliola glabroides Stev. on Nectandra patens, no. 7595 (type), Mayaguez, 
8867, Maricao. 
This species is quite distinct from all others seen in the characteristic 
manner of sheathing its host, also in the shape of the conidia. 
Arthrobotryum penicillium (Speg.), comb. nov.—Podosporium 
penicillium Speg. Fung. Puigg., n. 471. 
On Meliola panici E. on Panicum glutinosum, 5672, 5746, 5560, Monte 
de Oro, 4375, Ponce, 5947, El Gigante, 4801, 8934, Maricao, 4368, El Alto de 
la Bandera, 4389, Utuado; on Lasiacis divaricata, 4298, Manati, 6810, Arecibo; 
on Ichnanthus pallens, 7441, Mayaguez, 5755, Monte de Oro; on Gramineae 
indet., 6796 Arecibo. 
This form was originally described by SPEGAzzINI as the conidial stage of 
Meliola penicillata, and was later regarded by GatLtarp as the conidial stage 
of M. calva. 
ARTHROBOTRYUM CAUDATUM Syd. (figs. 5-7).—A portion of the 
type specimen was sent to me by Sypow, and its agreement with 
the specimens mentioned below is obvious. 
On Meliola pteridicola Stev. on Aneimia adiantifolia, 8015, near Utuado. 
On Meliola paulliniae Stev. on Casearia ramiflora, 512, 7745, Vega Baja, 9306, 
Barcelonata. On Meliola didymopanicis P. Henn. on Dendropanax laurifolium, 
8265, El Alto de la Bandera. On Meliola glabra B. and C. var. psychotriae 
Stev. on Palicourea, 6650, near Utuado, 468, Vega Baja; on Psychotria pubes- 
cens, 8032, near Utuado, 7741, 7732, Vega Baja; on Psychotria bertiana, 8646, 
$566, 8528, El Gigante, 8278, 8673, El Alto de la Bandera; on Palicourea, 
ro7o0b, 316, Mayaguez; on Psychotria sp., 5032, Vega Baja, 5044. 
What appears to be the same fungus was described as the conidial stage 
of M. penicilliformis by Gatttarp (Le Genre Meliola, 57, 1892). The species 
of Meliola itself being largely determined by its “conidial stage,” its validity 
may. well be doubted. 
e specimens following seem to agree with the preceding in all respects 
except that the coremia are usually pale at tip, apparently soft, with the base 
tan or darker, the head merely a somewhat thickened apical region and the 
conidia very pale. It seems that the fungus on Palicourea shows transition 
forms which connect the two types. 
On Meliola hyptidicola Stev. on Hyptis lantanifolia, 8130, Las Marias; 
on Hyptis sp., 5760, Monte de Oro. On Meliola longipoda Gaill. on Anona 
montana, 7561, Mayaguez.’ On Meliola glabroides Stev. on Piper aduncum,
