SUMMARY
1. | Diagnostic characteristics are provided for two new species, Myxotrichum thaxteri and M. conjugatum. | ||||
2. | The morphological development of these two species is discussed and illustrated. The formation of ascogenous hyphae and croziers precedes the production of asci. | ||||
3. | A comparison is made of the gametangial types represented in Myxotrichum uncinatum, M. thaxteri, M. emmonsii, and M. conjugatum. The value of gametangial morphology in taxonomy is discussed. |
