1918] STEVENS—MELIOLA PARASITES 243 
Meliola gaillardiana Stev. on Piper aduncum, 7794, Rio Arecibo. On Meliola 
glabroides Stev. on Nectandra patens, 8874, Maricao. On Meliola thouiniae on 
Winterana canella, 8548, 9075, Guayanilla. On Meliola gymnanthicola Stev. 
on Gymnanthes lucida, 8596, Guayanilla. On Meliola toruloidea Stev. on 
Cassia quinquadrangulata, 4015, Aibonito; on Spondias mombin, 749, Maricao. 
The short, plump, 3-septate conidia are often the most numerous types on this 
host. On Meliola paulliniae Stev. on Paullinia pinnata, 576, Vega Baja. On 
Meliola myrsinacearum Stev. on Ardisia guadalupensis, 7576, 7057, Mayaguez, 
3681, 8905, Maricao. The form described as conidia of M. pulveracea perhaps 
belongs here. On Meliola guignardi Gaill. on Turpinia panniculata, 3635, 
Maricao. On Meliola dipholidis Stev. on Dipholis salicifolia, 8549, Guayanilla. 
On Meliola monensis Stev. on Amyris elemifera, 6150, Mona Island. On 
Meliola furcata Lev. on Thrinax ponceana, 8590, 8017, Guayanilla. This last 
number often shows large variation in size of spores, some being very small. 
On Meliola guareae Speg. on Guarea trichilioides, 7464, Mayaguez. I would 
place here also the forms described as conidia of M. palmicola Gaillard, also 
perhaps those of M. patouillardi. 
Species indeterminate.—On Meliola mayaguesiana Stev. on 
Palicourea crocea, 7196, Lajas. Mycelium very scant, conidio- 
phores few and scattered. Conidia not seen. 
In addition to the species mentioned, other species which have 
been recorded on Meliola are H. podosporiopsis Pat. and H. argen- 
tinum Speg., both of which are 4-septate; the first on unknown 
host, the latter on M. argentina and M. uwvariae. 
Species of Helminthosporium which do not agree with any yet 
mentioned have been described as conidial stages of the following: 
M. manosensis, M. martiniana, M. evodiae, M. hyalospora, M. 
quercinopsis. 
Sterile mycelium, probably that of Helminthosporium, has 
been recorded on M. tomentosa, M. lanosa, M. clandestina, 
M. zig-zag. 
The “conidial stages” on M. substenospora, M. quericina, M. 
anomala, M. butleri, M. pulveracea, M. iquitosensis, M. psidit, 
M. monilispora, have been so briefly described that they are not 
recognizable. 
On the following species of Meliola the species of Helmintho- 
Sportum are perhaps distinct from those already mentioned: M. 
wrightit, M. cryptocarpa, M. mitchellae.
